Images, OLE frames, wipeouts, underlays, paper-space viewports and
drawing-view borders were selectable only on their outline. Each now
carries an interior pick surface (pick_tris over its rectangle, or the
triangulated clip polygon for a clipped underlay), ranked below edge
and fill hits so content drawn inside still wins the click. The
layout's own sheet ("overall") viewport is excluded — identified by
the Layout object's viewport link, since DWG files carry viewport
id = 0 and some center the sheet viewport off-origin — or it would
swallow every click over the real viewports beneath it. Drawing-view
borders draw nothing normally; they emit an invisible pick-only wire
whose rect outline appears while selected.

Section marks and drawing-view borders are now real acadrust entity
types instead of Unknown-with-extras, so the renderer dispatches on the
variant directly, the arrow-direction resolver reads the active viewport
off the ViewBorder entity, and selection / properties show "Section
Symbol" and "View Border" instead of "Unknown". View borders are
non-plotting and tessellate to nothing; both count toward the lossy
Save-As warning since they round-trip via their raw records.
Bumps acadrust for the entity promotion.

An INSERT attribute left with an empty value drew a "[]" placeholder: the
SingleLine tessellation fell back to `[value]` whenever every line was
empty, but that branch only fires once the value is already empty, so it
always produced bare brackets (and never carried the tag it was meant to
preview). On a heavily scaled block instance the unscaled brackets ballooned
across the sheet.
Render nothing for an empty value instead, matching AutoCAD, where a blank
attribute shows no text. An attribute definition previews its tag as a
non-empty value, so it never reached this branch and is unaffected.

A wide polyline with per-vertex varying widths rendered at its widest edge
(uniform-width ones were already exact). Draw the true taper instead.
`WireModel.taper_widths` carries a per-point full band width. The wire
instance (native slim + web fat) gains per-endpoint `world_hw_a/b`, and both
wire shaders interpolate `mix(hw_a, hw_b, which_end)` so each segment's band
narrows/widens linearly — depth-tested, and the linetype dash still applies.
Alignment (widths must match the tessellated points) is solved by building
both together: a new `TruckObject::TaperedLines(points, widths)`, filled by
`common::tapered_band_points` (straight = endpoints, arc = 16 samples with the
width lerped along it). to_truck routes a varying-width polyline here —
LwPolyline before the PLINEGEN split, Polyline2D at its return — while a
uniform-width one keeps the constant-band Contour path unchanged. `world_width`
stays the widest edge as the PDF-stroke + zoom-floor fallback.
Blocks fall back to the constant-widest band (`LocalWire` carries no
taper_widths).

Extends the wide-polyline shader band to the two cases the first pass left on
the hatch pipeline.
Polyline2D:
- A flat wide Polyline2D now draws its band from the centre-line wire
(`world_width`), same as LwPolyline (`polyline_band_width` handles both).
- A thickened wide Polyline2D extrudes a solid 3-D tube. `thick_wide_band`'s
body moves to a shared `common::thick_band_tube(origin, fills, thickness,
normal, to_wcs)`; LwPolyline delegates to it and Polyline2D calls it from
its thickness path. Tube edges read black for both kinds.
- The model-space wide-band hatch loop is deleted (both kinds now wire/tube).
Blocks:
- Block-internal wide polylines draw the shader band too. `LocalWire` carries
`world_width`; `emit_wire` scales it by the insert transform (average of the
X/Y axis image lengths) so the band tracks a scaled insert, and the scaled
width joins the batch `style_key`. `push_block_wide_fills` (the block hatch
band) is removed.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
A wide polyline's flat band was drawn by the hatch pipeline: a solid fill
with only draw-order depth. It ignored the entity linetype (the width
"crushed" the dash pattern) and showed through 3-D geometry in a tilted view.
Draw the band from the polyline's own centre-line wire instead. A new
`WireModel.world_width` (drawing units) makes the wire vertex shader expand
the quad by `world_half_width / world_per_pixel` (clamped to a hairline), so
the band is sized in world units and tracks zoom. Because it is now a wire:
- the GPU dash shader dashes the band by arc-length — the linetype applies;
- it is depth-tested at the polyline elevation — no draw-order see-through;
- no CPU band triangles or per-dash geometry are generated.
`world_half_width` rides in `WireConst` (native, replacing a pad) and the web
`WireInstance` (loc 14); both wire shaders branch on it. The tessellator sets
`world_width` from the LwPolyline width on the Contour / SegmentedLines arms,
and the model-space fill loop no longer emits a hatch band for any LwPolyline.
Pick still uses the band polygon (`pick_tris`).
Blocks keep the hatch band: `LocalWire` carries no `world_width` (finalize
zeroes it), so a scaled insert still scales its band correctly.

Entering a thickness (DXF 39 extrusion) on a wide polyline now works end
to end:
- The properties Thickness field is a General-group common prop, so it is
routed to apply_common_prop (set_entity_thickness) instead of the
geometry setter, which ignored it — the value was silently dropped and
reverted to 0.
- A wide polyline extrudes its whole band into a 3-D tube (outer + inner
walls with top and bottom caps), not just its centreline.
- The tube is real 3-D geometry, not a flat draw-order hatch: it renders
solid in every view mode with true depth, so nothing shows through the
walls. The flat 2-D band fill is skipped for a thickened polyline.
- A fill whose triangles span depth keeps its real depth (no draw-order
bias), so the extrusion's own edge wires stay in front of the surface
and remain visible instead of only the silhouette.
- The corner and cap edge lines read black, framing the coloured tube.

Rectangular paper viewports now go through the same GPU stencil clip as
non-rectangular ones: viewport_clip_boundary_ndc returns the four rect
corners (a full-target mask) instead of nothing, so the render path has
no rect/non-rect special case — every content viewport carries a clip
boundary and draws with stencil reference 0xFF.
With a single clip path, the old per-wire / -image / -wipeout scissor
mechanism is fully dead and removed: compute_*_scissors, the
*_pixel_scissors buffers, the project_scissor helper, the per-pass
set_scissor_rect blocks, the vp_scissor field threaded through
WireModel / ImageModel / HatchModel and their GPU mirrors (WireGpu /
ImageGpu / WipeoutGpu / HatchWebGpu), from_run's scissor parameter, the
scissor grouping in build_wire_buffers, and the is_arena_eligible gate.
Net -245 lines across 54 files.
Rectangular viewports still clip exactly via their own render rectangle;
the stencil mask is a redundant full-target no-op there, kept only so
the clip code path stays uniform. XCLIP keeps its CPU wire clip.

Re-evaluate AcDbField-driven MTEXT — date/login/document-property fields, table
formulas and object properties — against the current system instead of showing

OCS supplies only the environment (system clock, OS login, env vars) through a
FieldContext implementation, and hooks the resolved text into MTEXT rendering,
falling back to the cached value for anything it can't evaluate.

Lights, camera views and the geographic-location marker had no on-screen
representation. Add display glyphs for all three:
- Lights render through a new EntityType::Light: a cone/flashlight for spot
lights, a wire sphere for point lights, a sun for distant lights, sized in
screen space (fixed-world fallback).
- Camera views (perspective VIEW records) and the GEODATA "daisy" marker are
synthesized into the model-space resident wire set from the document, since
they are not entities.

The paragraph-start caret slot used the raw entity height, so a blank
line's caret stood entity-tall — many times the visible text when `\H…x;`
runs shrink it (5× on budweiser2018.dwg handle 50019). Size it to the
line's own text height instead (an empty line inherits the previous line's
height, the same rule `per_line_h` already uses for spacing).

Complete the editor/layout support for two MTEXT inline codes that were
parsed but not rendered:
- `\f…|i1;` set the font italic flag but layout only fed oblique from
`\Q`, so imported italic showed upright. Map font.italic to the same
15° slant the editor's Italic button uses (explicit `\Q` still wins),
and make that button recognise + clear the flag so imported italic can
be toggled off.
- `\~` (non-breaking space) was a normal Space atom, so lines could wrap
at it. Fold it into the word — it still renders as a space but no longer
breaks.

An empty `\P` paragraph carries no glyph to size it, so the per-line
advance fell back to the full entity height. In a small-text block (a
`\H0.2x` column) that blew a single blank line up to several times the
height of the text around it, shoving everything below it far down the
page. Size a glyph-less line by the last non-empty line's height instead.

Two defects in tabbed fields inside a multi-column MText:
- Stop positions are relative to the paragraph's own left edge, but the
tab logic compared them against the column-absolute `cursor_x`. In a
second column `cursor_x` already carries the column offset, so no stop
ever matched and the field shot off to the default 4-em grid, way past
the page. Measure against the column's `box_left` instead.
- A field after a center/right/decimal tab aligns on the stop, reaching
only part of its width to the right, but word-wrap flushed it left and
wrapped it off the line by its full width — dropping a wide decimal
number onto a fresh, un-tabbed line. Don't wrap the field that follows
an aligning tab.
Picks up acadrust b16137f (decimal stop position parse).

A `\t` reaching a center, right, or decimal (`D`) tab stop now aligns the
field that follows it — the run of words up to the next space/tab — instead
of just advancing the pen:
- decimal: the field's first `.` lands on the stop (a column of numbers
aligns on the decimal point; a field with no `.` aligns its end),
- right: the field's end lands on the stop,
- center: its middle.
The stop wins even when the field is wider than the room before it, so the
dot/edge stays put and the field overruns to the left, keeping the column
aligned. Left stops and the default 4-em grid are unchanged. Picks up
acadrust 162f194, which carries the tab-stop kinds.

`qj`/`qd` were stubbed to left. Now the layout fills the line to the
content width:
- Distribute (`qd`, and headings that reset with `q*` → justify) shares
the slack across every glyph gap — word gaps widen and letters spread
via tracking (LFF stroke fonts; TTF with zero letter-spacing spread
their word gaps only). Every line, including the paragraph's last.
- Justify spreads only the word gaps and leaves the last line ragged.
Bumps acadrust to 504281a, which parses `\pqd` as Distributed and
`\pq*` as Justified so these alignments reach the layout at all.

Several MTEXT layout fixes, all in the run-aware layout engine:
- Honour paragraph spacing (`\p…b#/a#`) and per-paragraph line spacing
(`\psm#/pse#`), which the parser already produced but layout ignored.
They are sticky per-field, so a `\pxb0.25;` set once applies to every
later paragraph — stacked paragraphs now read apart instead of running
together.
- Underline / overline / strike now continue across the blanks between
words: a decorated Space atom emits its own rule, matching the exact
advance lff gives the space so it meets its neighbours' rules.
- Anchor the first line by its own cap height rather than the entity
height, so a small heading (`\H0.2x;First column`) no longer opens a
full blank line above it; the column's first paragraph still opens its
own `\p…b#;` space-before as the top margin, so the heading sits where
the entity data places it.

A raster image reference now resolves through one memoised path shared by
the loader and the unresolved-reference placeholder:
- http/https URLs are fetched natively (rustls, 8s timeout, 32MB cap); a
local file is read as before. The web build never fetches. The cache is
cleared when a new document opens.
- Online, the fetched image displays; offline or on a broken/missing
reference, the frame + saved path text still shows. One resolver keeps the
two in agreement without fetching twice.
The raster is also clipped to its boundary: the image draws as the
triangulated clip polygon (ear-clipped) with per-vertex UVs instead of a
full quad, so pixels appear only inside the clip. Clip-boundary Y is raster
space (top-down), so it is flipped to the image's Y-up space in both the
outline and the clip triangulation so they align.

An IMAGE whose file can't be opened (a URL, or a missing/renamed file) now
draws its clip/frame outline plus the saved path as centred text in the
image colour — AutoCAD's broken-reference placeholder — instead of an empty
frame. OCS never fetches remote paths. Bumps acadrust so the entity's path
is populated from its ImageDefinition.

A SOLID's filled quad and a dimension/MultiLeader text background are flat 2-D
overlays that should draw in wireframe and shaded alike, but face3d_gpu
classified fills by `!fill_tris_low.is_empty()` — and a 2-D fill at UTM scale
carries a double-single low residual for precision just like a real 3-D mesh
face. So the arrowhead fill and the "5;8" cyan text background were routed to
the 3-D buffer and only appeared in shaded mode, vanishing back to nothing on
return to wireframe.
WireModel now carries an explicit `fill_is_3d`: true only for a real surface
(PolyfaceMesh / PolygonMesh face, set in the tessellator), false for every flat
overlay fill. face3d_gpu classifies on the flag, so 2-D fills stay in the
always-visible buffer while keeping their low residual (and UTM precision).
Verified on budweiser: the `_BoxFilled` arrow SOLID and the dim '5;8' MTEXT
background both tessellate with fill_is_3d = false.

A 2D SOLID's `to_truck` emitted only its 4 perimeter edges; its fill came from
a solid-fill HatchModel the scene injects for top-level SOLIDs. That injection
never runs for a SOLID nested in a block, so a filled arrowhead like the
`_BoxFilled` dimension arrow rendered as a hollow box outline.
`to_truck` now also emits the two fill triangles (visual quad p0→p1→p3→p2, the
second degenerate for a triangle SOLID). Block expansion carries fill_tris, so
the arrowhead — and any SOLID inside a block — renders filled; the dimension /
MultiLeader / mesh 2-D fill pass already routes these to the flat fill batch.
Top-level SOLIDs also keep their HatchModel fill; the duplicate is invisible for
the opaque solids these are.
Verified on budweiser dim 3728: the `_BoxFilled` arrow SOLID now tessellates to
fill_tris (2 triangles) instead of an empty fill.

An OLE2FRAME drew only a rectangle-with-X placeholder. AutoCAD shows the OLE
object's cached presentation image, which the DWG stores as a BMP embedded in
the OLE data blob (a BITMAPFILEHEADER "BM" + DIB).
`ImageModel::from_ole2frame` scans the blob for a self-consistent embedded BMP
(validating the DIB-header size, so a metafile/other-format OLE cleanly falls
back), decodes it with the `image` crate, and builds the textured quad at the
frame rectangle with a per-corner double-single split so it stays precise at UTM
scale. The scene's image collection now feeds OLE2FRAME entities through it
alongside RasterImage. The placeholder's diagonal X is dropped — only the frame
border is drawn now, so it no longer crosses over the bitmap.
Verified on budweiser handle 3088: the 32×32 embedded bitmap decodes to RGBA
with the expected colours (yellow upper-left, blue centre, red lower-right),
upright and positioned at the frame corners.

A fit-point SPLINE (no control vertices) was drawn with Catmull-Rom through its
fit points, which ignores the stored begin/end tangents and uses local slopes.
An open curve then peeled away from the true shape at its ends — budweiser's
handle 2735 lost the tangent-driven overhang at its top end.
A fit spline is the C² cubic that passes through every fit point clamped to the
stored end tangents. Replace Catmull-Rom (kept only for closed splines, whose
wrap the clamped solve doesn't model) with `fit_spline_polyline`: chord-length
parameterisation (honouring knot_parameterization), a tridiagonal Thomas solve
for the knot slopes with clamped-tangent or natural end rows, and Hermite
evaluation. Verified on 2735: the curve passes through all five fit points and
its ends follow begin_tangent/end_tangent (dir·tan = 0.997).
Also fixes grip-selection: grips()/apply_grip() only ever looked at
control_points, so a fit spline (0 CV) showed no grips and couldn't be
grip-selected or edited. Both now fall back to fit_points when there are no
control points — dragging a grip moves the fit point and the curve re-fits on
the next tessellation, keeping the end tangents. The mirror path already
transformed fit_points; move/rotate/scale run through acadrust.

A cylinder's wireframe showed only its two rim circles, so from the side it
read as two disconnected ellipses rather than a cylinder. AutoCAD draws
ISOLINES — a fixed set of longitudinal lines on each curved face — so the
surface reads from any angle.
`collect_isolines` walks the cone-surface faces (cylinder and cone), recovers
each face's height and angular extent with the same logic `tess_cone_face`
uses, and emits `header.isolines` (default 4) longitudinal segments from the
bottom rim to the top rim. They are appended to the feature-edge line list, so
they ride the existing body transform, double-single split, and top-level /
per-INSTANCE re-split for free.
Being part of `edge_verts`, they inherit the edge pass's gating: drawn in the
wireframe modes and in shaded-with-edges, hidden in plain shaded — matching
where AutoCAD shows isolines. `isolines` is threaded from the header through
the tessellation entry points alongside `facet_res`.

Two layout fixes on the same MTEXT (budweiser2018.dwg handle 2609 / 8782).
Fraction size: `\H0.7x;\S1/2;\H1.429x;` is how a 70 %-scaled fraction is
spelled, so the 0.7 already *is* the fraction's size — the earlier constants
shrank each half again on top of it and buried the stack inside one line.
A half is now near the run height and the stack stands about twice that: the
numerator rises past the cap and the denominator sits on the baseline, the way
a fraction is meant to grow past its line rather than be squeezed into it.
Alignment persistence: a `\p...;` block stays in force until the next `\p`, so
a paragraph opened by a bare `\P` / `\N` inherits it. The parser records only
the literal codes, so the second line of a centred or right column
(`\pxqc;col2\P≡`) fell back to the left edge while its heading stayed aligned.
Layout now carries a paragraph's whole property block forward to any paragraph
that sets none of its own — measured, the column symbols land on the same
centre / right edge as their headings.
Kept in the layout adapter rather than the parser: acadrust faithfully records
which paragraphs carry an explicit `\p`, so persistence is a rendering
interpretation, and the literal record stays available to an editor.

Two things an MTEXT can ask for that the layout ignored, both found on the
same drawing (budweiser2018.dwg handles 8782 and 2609).
Columns: `column_data` was read but only ever reached the properties panel,
so a three-column MTEXT ran as one stacked block. Each line now carries the
column it belongs to, the row counter restarts per column, and wrapping
measures against the column rather than the block — measuring against the
block would let a line run across the gutter and over its neighbour.
Paragraph alignment already worked, which is what made the bug read as
"columns are there but misplaced": `\pxqr;` pushed col3 to the right edge
either way.
Only explicit `\N` breaks move to the next column. A column that fills up
does not spill into the next on its own — `heights` / `auto_height` are not
read, so a column runs as long as its content.
Stacking: `\S1/2;` was flattened to the literal "1/2", which is why the
line then overflowed its 7.26-wide box and dropped `°C ª` onto a second
row. The halves now share one horizontal slot, drawn at a shrunk height
with the numerator lifted, so the slot is as wide as the wider half. `^`
stacks without a rule; `#` stays inline `num/den`, which is what a slanted
fraction reads as and needs no second baseline.
The fraction rule rides a run-less stroke group: a group carrying a
`GlyphRun` renders as SDF quads with its strokes suppressed, a run-less one
keeps them, and the rule is plain geometry rather than a glyph.

A wide polyline draws a solid band, but hit-testing only ever saw the
centreline 8 px out, so a donut could only be selected by clicking the
phantom circle inside the disc it paints. `self.hatches` — the map the
hatch pick channel walks — is filled from HATCH and SOLID alone, so the
band `wide_fills` produces was drawn (via `synced_hatch_models`) and never
picked.
The band rides in on `pick_tris`, the same channel a thickness wall uses:
`wide_fills` already computes it, so it costs one tessellation and inherits
the block transform. It ear clips rather than fans — an arc band is an
annular sector, concave on its inner edge — reusing `triangulate_planar`.
Wiring `pick_tris` through `Lines` alone was not enough: a plain wide
polyline leaves `to_truck` as `Contour`, and a PLINEGEN=0 one as
`SegmentedLines`. Both now carry it.
This needs the wire's cullable box to cover the band, and it did not.
`bounding_box()` boxes a polyline's stored vertices, knowing nothing of the
width painted around them: a donut's two vertices sit on one horizontal
line, so the box had zero height and rejected every click on the disc
before any triangle was tested. Every site that stamps the entity box onto
a wire now goes through `set_wire_aabb`, which widens it over `pick_tris`
(a no-op for the entities that have none, which is nearly all), and the
block cache chains `pick_tris` into its own box for the same reason.
That box was already too small for the centreline itself — an arc leaves
the vertex box — so a donut was unselectable at its top and bottom at
enough zoom. Widening fixes that too.
Verified end-to-end: tessellate a width-0.5 donut on a 0.05 centreline
radius, then `click_hit` five points 20 px clear of the centreline — all
land, and a click outside the disc still misses.

DXF codes 43 / 40 / 41 store a polyline band's full width, and
`polyline_segment_fill` offsets ±hw about the centreline, so the stored
value has to be halved. Both `wide_fills` passed it in whole and drew
every wide polyline at double width.
The codebase was writing the spec value and reading it as something else:
`make_donut` stores `outer_r - inner_r`, a full width, which `wide_fills`
then treated as a half-width. So OCS mis-drew even its own donuts.
Seen on budweiser2018.dwg handle 2579, a donut of width 2.2 on a 1.1
centreline radius: it should fill out to radius 2.2 and instead reached
3.3 — a disc 1.5× its real size, overflowing the square it sits in.
Affects every wide polyline, so TRACE and PEDIT-widened runs come back to
true size too. The writers already stored full width and are left alone,
as is the property panel, which shows the file's own value.

Selection tested a flat 8 px radius around each wire's centreline and
nothing else, so two things the user can see were not pickable.
A wire renders as a band `line_weight_px` wide, so pick now widens to that
rendered half-width via `pick_tolerance_px`, mirroring the wire shader's
`select(0.5, half_width, lwdisplay_enable)`. Behaviour is unchanged for
every standard weight (the widest, 2.11 mm, renders 7.97 px half-width —
just under the 8 px threshold); this keeps the two sides from drifting
apart if the display boost in `lineweight_to_px` ever changes.
Entities extruded by a DXF thickness draw their wall as four edges with
nothing in between, so the interior was a hole the cursor fell through.
WireModel gains `pick_tris`: triangles hit-testing treats as solid and the
renderer never uploads. Kept apart from `fill_tris` because that channel
reaches the GPU, and a wall that rendered shaded would change how every
thickness drawing looks. Ranked below `fill_tris` — those are drawn, these
are not, so where they overlap the drawn face is what the user means.
Walls are dropped when a wire is projected into a floating viewport:
`points` are reprojected and clipped into paper coords there, so cloned
model-space triangles would hit-test at a model-scale offset. Extruded
entities stay selectable by their edges, which do get projected.
The wall loop runs on every hover that misses everything else, so it
rejects on the wire's AABB first — an extruded circle is ~128 triangles
and a drawing full of thickness would otherwise project every wall on
each mouse move.

MLINE dashed elements were fully CPU-expanded (apply_along) — one wire per
dash — to keep the parallel lines in phase. Move pure-dash elements onto the
GPU dash shader and end-align every element to the multiline's centre-line so
they share one interior phase.
- wire_distances now accumulates arc-length from the double-single (high+low)
points, so the dash phase stays precise at UTM coordinates. f32-high-only
deltas quantised ~0.1 there and drifted the parallel lines apart — the
original reason MLINE dashes were CPU-side.
- New WireModel.dash_align_end carries a shared begin/end dash length. The
shader uses it as align_end for every parallel element (the interior phase
depends on align_end, not the wire's own length) while align_total stays the
element's own length, so each still ends on a dash at its own endpoint.
- MLINE tessellation derives that length once from the centre-line, routes
pure dash/space/dot elements to the GPU pattern and text-bearing elements to
apply_along.
- apply_along gained an "A"-type mode (shared reference length): a solid
begin/end dash and a phased interior, so its dashes — and embedded text —
line up with the GPU-dashed sibling elements instead of tiling from start.
Pure-dash MLINEs now cost one WireModel + pattern per element instead of N
segments; single (non-MLINE) entities keep the from-start tiling unchanged.

DET pipe walls now carry the stroke pattern (dash_from_start), which
tiles from each wall's own start vertex and skips the A-type end
alignment that was force-lighting a solid dash under the end symbol.
Two rendering fixes on top:
- Dedup the host polyline's vertices before offsetting the walls. Some
DGN pipe polylines carry trailing duplicate end vertices; a zero-length
segment gave offset_xy a degenerate normal, leaving that vertex
un-offset and folding the wall down to the centre line. The two walls'
fold segments met at the centre and drew a spurious line linking them.
- Re-key the symbol (end circle / half-ellipse) wires to the host handle
so the whole pipe picks and selects as one entity instead of the
symbols acting as separate phantom entities.

Multilines were drawn with a fixed ±scale/2 two-line guess in the entity
colour, ignoring the MLINESTYLE entirely, so a drawing's custom style (per-
element offsets, colours and linetypes) was lost — a red/yellow multiline
rendered as a white box.
- mline.rs: resolve the MLINESTYLE (by style_handle, then name) and build one
parallel line per element from its offset x scale + justification shift.
- tessellate.rs: special-case MLINE (like Leader) to emit one WireModel per
element in the element's own colour, CPU-dashing every element through
apply_along so the parallel lines stay in phase.
- linetypes.rs: render a drawing's OWN complex linetypes (embedded text/shape),
document definition first and the bundled .lin catalog only as a fallback, so
a file-defined text linetype like PLYN shows its text.
- Run the dash/glyph layout in a local frame (f64 origin subtracted, re-split to
double-single after) so spacing stays precise at UTM coordinates, and pass
tracking = 1.0 so embedded text keeps its letter spacing.
Cargo.lock pins acadrust to the MLINE->MLINESTYLE handle-link reader fix.

A symbol font's glyphs straddle the cap box by design — the diameter sign's
stroke overhangs it top and bottom — so anchoring a top-aligned line by the
nominal cap height alone hung it above where the drawing puts it, by the size
of the overhang.
Measure how far the first line's glyphs reach above the baseline and anchor by
that when it exceeds the cap. The fold is one-directional, so ordinary letters
(which stop at the cap) keep their exact previous offset.
The test pins the benchmark's own case: without this, the glyph draws from
0.7372 instead of the insertion point — matching the offset measured against
the file's own LINE endpoints for handle 1087.

A tolerance drew one row of ASCII soup — "RUN | ANGtol(M) | ..." — about
a tenth of its proper size. Six defects, each independent.
Rows were split on the two-character string "^J". A DWG stores a raw
newline, and the text-DXF reader rewrites the on-disk ^J to one before we
see it, so that split never fired on either mainstream path and every row
collapsed into the first. It now normalises all four spellings the break
arrives in — including the \P our own DXF writer emits, which made
open-DWG → save-DXF → reopen asymmetric.
Symbols were replaced with ASCII labels from a table that was itself
wrong: it read r as circular runout, n as angularity, p as position. The
font's own encoding says concentricity, diameter, projected tolerance
zone, and the benchmark's pre-exploded reference agrees. That table was
an inversion of acadrust's, which is self-contradictory — it binds n to
two different meanings. Do not re-derive from it.
The frame is a proportion of the character height: a compartment spans
-h..+h about its row's centreline, so it is 2h tall and the margin falls
out of that. It was built as height + 2*DIMGAP instead, which is a
different entity's geometry — DIMGAP sizes the dimension line's break and
the rectangle around a basic dimension, where it genuinely applies twice
per axis. Even fed a self-consistent style that can only ever produce
1.5h, so it was wrong in kind rather than mis-fed.
Height came from the entity's own field, which a DWG never sets — the
reader carries only the style's handle, leaving a small non-zero default
that a "> 0" test happily used. It now resolves the style by handle first
and name second: a DWG records the handle and defaults the name, a DXF
the reverse, so matching on the name alone would have picked the wrong
style for every DWG-read tolerance. An entity may also override single
style variables on itself, and this one halves its character height that
way; ignoring that drew the frame several times too large.
Rows stacked upward, every row inherited the widest row's columns, and
one full-width border boxed them all — none of which showed while the
parse only ever produced a single row. The insertion point sits on the
first row's centreline; anchoring the frame's bottom-left there offset it
by its own height, and by an amount that changed with the row count.
Cell text ran together because the glyph run asked for no letter spacing
while the width measurement assumed the font's own, so the characters
crowded inside correctly-sized boxes. Compartments are also measured by
what they draw now: the pen advance stops one letter-space past the last
glyph, and counting that made every one of them too wide.
Symbols come from a bundled stroke font, restored from this repository's
own history: it shipped QCAD's gdt.cxf until the text engine moved from
CXF to LFF, which removed every .cxf and left nothing in their place —
the ASCII labels date from exactly there. Converted to LFF, keyed by the
letter its \Fgdt;X escape carries, and registered under that name like
any other font, so a switch to it resolves through the ordinary lookup:
an MTEXT carrying the escape, or a text style named gdt.shx, reaches it
too, with no code of their own. The geometry is public domain by explicit
waiver; provenance is in the file's header.

A 3ft object measuring 35.9999" (float noise) printed "2'-11 1"" because the
architectural and fractional formatters split feet/inches/fraction *before*
rounding. A fraction that rounded up to a full unit (16/16 -> 1/1) reduced to a
bare "1" and leaked out with no carry into the inches or feet.
Round on the fraction grid first using integer ticks, then decompose, so carries
propagate: 35.99" now reads 3'-0" instead of 2'-11 1". Adds regression tests.

The "Dim line color" row on Leader and Dimension entities was
read-only: an earlier attempt wired it to Leader.override_color, which
acadrust never serialises, so the pick was lost on save. Store it
instead as a standard ACAD_DSTYLE per-object dimension-style override
(DXF code 176, an ACI index) through the existing dim_override codec,
so it round-trips through both DWG and DXF like the other dim
overrides. RGB picks collapse to the nearest ACI, matching the rest of
the dim-colour stack (dimension styles are index-only through the file
layer). The renderer prefers the override over the style's DIMCLRD.
The write branch is guarded to leaders and dimensions so a mixed
selection cannot stamp the override onto other entity types.
Bumps acadrust to c9fe982, which carries parsed XDATA onto dimensions
on DXF read (it was dropping common.extended_data), so the dimension
override persists on DXF save as well as DWG.

The Columns row becomes a No columns / Static / Dynamic picker, with
editable column count / width / gutter rows that are live only when
columns are on. Switching a plain MText to columns seeds a consistent
count / width / gutter (dynamic defaults to auto-height) so the stored
layout isn't half-defined; the rows then refine it.

A legacy leader's Lines & Arrows / Text / Fit rows are now editable
per-object overrides of its dimension style, stored in the standard
ACAD_DSTYLE XDATA record (new src/entities/dim_override.rs codec). Arrow
block, arrow size, dim-line lineweight, text offset, vertical text
position and overall scale each prefer an override over the style; the
renderer honours arrow size / block / overall scale and the dim-line
lineweight, so an edited leader redraws at its new arrow and weight.
XDATA edits go through a new dispatch::set_entity_xdata, which registers
the application in the APPID table (the DWG writer drops records for an
unregistered app) and drops that app's stale verbatim EED block (which
otherwise wins over the structured record on a DWG save), so edits and
clears round-trip. The hyperlink editor moves onto this path too.
Dim-line colour stays read-only: it would live in the leader's
override_color, which the file layer doesn't serialise, so making it
editable would silently lose the pick on save. Picking "Closed filled"
writes an explicit null-handle arrow override rather than clearing, so
it sticks even when the style's arrow differs; an unparseable numeric
entry is ignored instead of wiping the stored override.
Note: the DXF entity writer only emits XDATA for hatches, so these
overrides (and hyperlinks) currently persist on DWG save but not DXF —
an acadrust-side gap to close separately.

Render: annotative-ness is resolved centrally in scene::annotative::is_annotative
(per-object context dictionary, legacy XDATA, or annotative style) so the bake and
the properties panel agree. Text, dimensions, tables and blocks now display at the
current annotation scale in model space. An annotative block scales as one uniform
unit about its insertion point — its internal geometry and attributes are carried by
that scale instead of being scaled individually, fixing the block-attribute size
regression. Tables scale their column/row/margin geometry.
Properties: the handle- and flag-backed rows are now editable pickers — MLEADER
multileader style / text style / arrowhead / leader linetype, General Material, and
Plot style (named plot-style mode only; the color-dependent mode stays read-only,
which is correct). A picked name is resolved back to its handle in the update loop,
where the document is in scope. Annotative Yes/No and the annotation-scale row are
shown per object.

Match the entity Properties panels to the standard CAD layout and
web-verified behaviour:
- Text: combined Justify (horizontal x vertical) dropdown; Position and
Text-alignment rows become editable/grayed by justification; drop the
Annotative-scale row.
- MText: combined Justify; editable Direction, Line space distance
(back-solves the factor) and Line space style; Defined width/height
gated on column mode.
- MLeader: regrouped to match the palette - drop the Leader Structure
group (fold landing rows into Leaders), gate Text vs Block on content
type, full 9-value attachment label set, resolve handle-backed rows
(style, text style, arrowhead, linetype) to names.
- Leader: Lines & Arrows / Text / Fit are resolved from the dimension
style (arrowhead, arrow size, dim-line lineweight/colour, text gap,
vertical text pos, overall scale); Current Vertex navigator; combined
Type; Geometry group after General; no 3D-Visualisation group.
- General: rename "LT Scale" to "Linetype scale"; show ByLayer
transparency by name. Add shared num_prop helper for conditionally
editable numeric rows.

Render MultiLeader labels from the stored context fields instead of
re-deriving them:
- Draw each leader line with the line's own path type (code 170) rather
than the MultiLeader's overall/style type. A spline-style leader can
carry straight lines; splining a straight two-point run through
Catmull-Rom bowed it, so the leader looked wavy with a dirty elbow.
- Drop the stray landing segment that ran from the dogleg end up to the
text's top-left insertion, leaving just the horizontal dogleg.
- Anchor the horizontal-leader text so its bottom line sits at the
connection point (the box then spans connection.y → text_location.y,
matching the writer's content_base_point + landing_gap geometry).

Completes the f64 migration on the CPU data path: the only f32 left now
is the GPU/render/screen layer, which is architecturally required (wgpu
vertex buffers and iced are f32; f64 vertices would double memory).
- EntityTransform::Rotate.angle_rad and Scale.factor are now f64 (the
transform was already applied in f64 around the DVec3 center, so this
only preserves the typed angle/factor). apply_standard_transform and
apply_standard_scale take f64.
- CmdResult::ExtrudeEntity.height and AlignSelected.{angle_rad,scale}
are f64; the EXTRUDE height parses as f64.
- defaults.rs (last-used construction values: circle radius/diameter,
rotate angle, scale factor, offset/fillet/chamfer distance, array
spacing/counts/angle) moved from Cell<f32> to Cell<f64>. Array counts
round-trip through u32 (exact below 2^53).
- Consumers in circle/array/fillet/offset/rotate/scale/align/solid3d and
dimension.rs rotate_point/scale_point follow. `as f32` is kept only
where a value feeds a WireModel rubber-band/ghost (the preview path is
screen-space f32).

Rewrite the in-app MTEXT editor to run on acadrust's structured
MTextDocument model end-to-end: load via parse_mtext, edit a flat Cell
model, serialize via to_mtext_string. Retires the hand-rolled format-code
string handling, the parallel visible_spans parser, the composed_value
prefix, and the Edit-raw-code tab.
Selection and copy:
- double-click selects the word, triple-click selects all (click-counting)
- Ctrl+A selects all text
- Ctrl+C copies the selected text to the clipboard
Formatting:
- per-selection Bold/Italic/Underline/Overline/Strike/Case/Alignment
- Bold renders as a visibly thicker SDF pen, keyed (family, char, bold)
through the whole text pipeline; the resolved style font name is stamped
so the \f...|b1; code survives serialization
- per-selection font and color changes
- editor color dropdown reuses the Properties panel color selector
Global toolbar defaults (font/color/oblique/width/tracking) fold onto the
document as real span properties instead of a leading code prefix; a
trailing empty paragraph is preserved so Enter at the end keeps its line.

Two defects in the in-app MTEXT editor, both surfaced once the preview
text became visible:
1. Invisible preview text. After the SDF text migration, tessellate emits
glyphs as SDF quads on `text_verts` and leaves the polyline `points`
empty, but the editor preview draws on a 2D canvas that can't run the
SDF shader — so only the selection box showed. Add a `force_text_strokes`
parameter to tessellate: when set, TEXT/MTEXT run-groups also emit their
glyph outline strokes as points. The preview passes true (real stroke
font, aligned with glyph_boxes); every other caller passes false and
keeps SDF-only text.
2. Enter did not start a new line. mtext_type inserted a literal newline,
but the MTEXT layout only breaks on the `\P` code (a raw 0x0A is a break
only to the caret logic). Normalise every literal newline — from Enter or
a multi-line paste — to `\P`, so the line breaks and the saved value
stays standard.

Gradient Type (One/Two color), Color 1 and Color 2 editable via a generic field-keyed colour picker path. Background colour editable and stored as HATCHBACKGROUNDCOLOR extended data (group 1071 true colour), rendered in OCS as a solid backdrop drawn behind the pattern. Hide Origin X/Y for gradients (pattern-only concept) and drop the redundant gradient rows from the pattern branch.

Merge duplicate Type into pattern_type; Type/Associative/Island detection as dropdown/toggle; Angle/Scale/Spacing/Origin X-Y editable; Color via picker. Reorder Pattern group, drop redundant Color/Transparency/Layer override and the Misc section. Wire the pattern origin (per-line base_point) into the render (x0/y0 relative to world_origin) so it affects dashed/offset patterns; add a circle origin grip at the hatch centroid (new GripShape::Circle).

Single Geometry section: Start/Center/End points, Major/Minor radius (editable; minor derives ratio), Radius ratio, Start/End angle editable. Major/Minor axis vectors, parameters, Length and Normal kept read-only at the end.
