A 35-unit arc sweeping 6.5e-7 rad has arc length 2.3e-5 — past the
arc-length floor — yet start/mid/end bow off the chord by only ~2e-12.
truck's 3-point circle_arc fit then returns a near-infinite radius and
parameter_division subdivides without bound, hanging the load. Gate on
the sagitta (r·(1−cos(sweep/2))), the true measure of the fit's
conditioning, so long thin arcs survive and sub-precision ones drop.

sample_layout_03/04.dwg would not open: a periodic 9-control-point spline
with every control point pinned at the origin (zero extent) reaches truck's
parameter_division, which never converges on a zero-length curve and hangs
the first-frame tessellation. The spline passed every existing guard
(finite points, no knots, degree 3). Reject splines whose control-point
extent is sub-precision (< 1e-6 on all axes).
Verified: all five sample_layout DWGs now load + tessellate (03/04 went
from a hang to ~356 ms; 01/02/05 unchanged, no valid spline dropped).

DWG stores the current text/dim/multiline style as a header handle; the
writer keeps a valid stored handle and otherwise falls back to Standard,
so a Set Current change (which only updates the name) was lost on DWG
save. Treat the current-style names as the source of truth and re-resolve
the header handles from them at save time, alongside the table/multileader
variable-dictionary sync. Now every current-style choice round-trips
through DWG, not just DXF.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
On save, mirror the current table/multileader style from the header into
the variable dictionary (CTABLESTYLE / CMLEADERSTYLE DICTIONARYVAR
entries) so a Set Current choice round-trips through DWG, which stores
them there rather than in the header. Done once in save_as_version (the
shared clone point), so every save path and both formats stay in sync.
No-op when the document has no variable dictionary (fresh files).
Verified: mutate the entry, write+read a real DWG, value survives.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
DWG has no header field for the current table / multileader style — they
live in the variable dictionary as DICTIONARYVAR entries keyed CTABLESTYLE
/ CMLEADERSTYLE. Resolve them on load via the document's dictionaries and
set the header names, so the green ✓ marks the right style for DWG files
as well (DXF already worked via the header vars). A missing entry leaves
the value untouched, so there is no risk to the binary header parse.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
- The current-style marker is now a green ✓ in its own fixed-width column
so names stay aligned; rendered as a separate coloured glyph rather than
baked into the label string.
- Resolve the current text / dimension / multiline style from the handle
the DWG header stores into the name the app reads (fix_current_style_names
on load). DXF already provides these as names ($TEXTSTYLE / $DIMSTYLE /
$CMLSTYLE); DWG only stores handles, so the marker previously always fell
back to "Standard". Only overrides when the handle resolves.
Note: table and multileader current styles are not surfaced by the file
reader (no header name/handle exposed), so those markers still default to
the app's active selection until acadrust exposes them.

Large survey drawings (105k entities, multi-million unit extents) could
exhaust all RAM + swap on one core during load and get OOM-killed before
display. Two parser-garbage entities slipped past the corrupt-entity
purge and blew up truck's parameter_division tessellation:
- Near-zero-sweep arcs: the zero-sweep guard only caught sweep < 1e-9,
but a tiny non-zero sweep (e.g. 1.6e-6 rad) still places start/mid/end
within truck's coincidence tolerance and recurses unboundedly. Gate on
arc length (radius x sweep) instead so large-radius small-sweep arcs
(still visible curves) survive while sub-precision arcs drop.
- Desync splines with 100k control points and an invalid knot vector had
no guard at all. Add a Spline arm rejecting the 100k desync signature,
non-finite control points, degree < 1, and bad knot vectors.
Also cap complex-linetype dash expansion (complex_lt::apply_along) at
1e6 pattern repeats, falling back to a solid stroke — a latent OOM of
the same class on map-scale entities carrying a finely-scaled pattern.
Adds regression tests for the arc-length and spline guards.

New layers were added to the table with a NULL handle, and the first
patch used the non-advancing `next_handle()` getter, so two new layers
(or a layer and the next allocated object) shared one handle. The DWG
format is handle-based, so the collision dropped the layer on save;
DXF is name-based and survived, which is why a rename appeared to fix
it.
Allocate a unique advancing handle via `allocate_handle()` in LAYER NEW
(panel + command line) and on rename when the source handle is invalid.
Rename now also clones the whole record so colour/linetype/lineweight
are kept, not just the flags.
Adds DWG/DXF round-trip tests covering one and multiple new layers.

The purge scan tests every entity with is_entity_corrupt, whose
per-vertex finite/extent checks on large polylines dominate. Detection
is pure and read-only, so gather entity refs in one pass and test across
cores with rayon; removal stays serial (remove_entity needs &mut doc).
Cuts the "purge" span in the open-time breakdown on polyline-heavy files.

Phase 5.2. Time each open phase — parse, purge, derived-cache build on
the loader thread, plus xref resolve on the UI thread — and emit a
breakdown line on open completion:
parse 1240ms · purge 80ms · caches 340ms · xref 60ms · total 1820ms
Makes open-time regressions (and the wins from 1.1 / 2.4) visible at a

Phase 4.1. Handle / u64 keys dominate the hot maps (block_defn,
hatch / image / mesh caches, draw-depth map, viewport wire caches);
the default SipHash is wasted work on integer keys. Alias the std
types to rustc_hash::FxHashMap / FxHashSet crate-wide so every map and
set — including the cross-module draw-depth map shared between scene
and the GPU pipelines — uses the faster hasher consistently.
Mechanical: no behavioural change. Constructors moved from ::new() to
::default() (Fx variants carry no RandomState). Build + 13 tests green.

Phase 1.1: resolve_xrefs now purges corrupt entities inline as it
merges each xref and returns the dropped count, removing the second
full-document purge_corrupt_entities walk in the FileOpened handler.
Every xref-bearing open saves one O(N) entities() pass.
Phase 2.4: split compute_world_offset into offset_prep / offset_centroid
/ world_offset_from_centers; centroid accumulation now rides the existing
cache-handle walk in build_derived_caches. Two O(N) entity walks collapse
into one, with identical MSPACE-membership filtering preserved.

The truck B-rep pipeline is Z-up (solids extrude/raise along Z, profile
wires convert pass-through), but two spots still assumed a Y-up world:
- REVOLVE swapped the axis/origin to (x, z, y), so the revolve axis sat
in the XZ plane while the profile sat in XY → wrong solid. Use the
axis/origin straight through.
- OBJ import kept Y-up coordinates as-is on the (now Z-up) viewport, so
imported meshes lay on their side. Rotate +90° about X on import
(positions + normals): (x, y, z) → (x, -z, y).
EXTRUDE (sweep along +Z) and the box/cylinder primitives were already
Z-up and unchanged.

Both the on-screen paper canvas and the PDF / print pipeline only knew how
to draw the boundary outline of pattern hatches (ANSI31, ANSI37, dotted
brick, etc.) — the actual hatch lines were a GPU-only feature, so any
paper-space view or PDF export showed a hollow polygon where there should
be ruled fill.
Add a CPU rasteriser as `HatchModel::pattern_segments()`:
- builds an edge list from the boundary, splitting at NaN sentinels and
closing each sub-path so even-odd inside tests handle islands / holes;
- for every PAT family computes the world-space step vector
(`(dx,dy)` rotated into the family's frame, scaled by `model.scale`)
and the inclusive k-range bounded by the boundary AABB plus a 4096-
line safety cap;
- intersects each line with every boundary edge, sorts the hit
parameters, walks them in pairs (even-odd) and emits one segment per
in/out interval. Dash patterns are walked along each clipped span with
phase preserved via `t mod period`, matching the GPU shader's
absolute-t dash evaluation;
- pattern origin (`family.x0 / y0`) is rotated by `angle_offset` and
scaled the same way as `hatch_batched.wgsl`, so PAT patterns with
non-zero origins (brick / offset herringbone) line up with the GPU
render.
`paper_canvas::draw_hatch` and `pdf_export::emit_hatch` now route
pattern hatches through this rasteriser; solid / gradient hatches keep
their existing fast paths. The previous outline-only behaviour was a
visible regression on every layout containing a ruled fill.
Co-Authored-By: Claude Opus 4.7 <[email protected]>
The PDF / print pipeline only walked `WireModel.points` (lines), so every
hatched region disappeared the moment a sheet left H7CAD. Route the same
`paper_canvas_hatches()` / `paper_canvas_wipeouts()` lists that the
on-screen canvas consumes into `pdf_export::export_pdf` and
`print_to_printer::print_wires`, and emit each one as an
`Op::DrawPolygon` with the EvenOdd winding rule so multi-ring boundaries
(islands / holes) render correctly:
- Solid → fill the boundary polygon in the hatch colour.
- Pattern → stroke the outline (PAT line families stay procedural;
follow-up work will rasterise them into segments).
- Gradient → fill with the averaged colour, mirroring paper_canvas.
Wipeouts emit first, then hatches, then wires — same z-order as the
on-screen canvas, so wires draw on top of the fills they belong to.

Adds vertex-coordinate, thickness, and dimension-validity checks to
`is_entity_corrupt`. Sample files with degenerate Arcs (radius ~5e-14
and zero sweep) or 100k-vertex LwPolylines at coords ~1e244 used to
pass the previous check, then crash inside truck's parameter_division
with a 3 GB allocation.

Property-panel coordinate display and block-insert scaling were both
hard-coded, ignoring the document's stored unit configuration.
- LUNITS / LUPREC: edit_prop() now formats values through a thread-local
UnitContext seeded by refresh_properties(). Decimal / Scientific /
Engineering / Architectural / Fractional all render correctly without
threading the document handle through every entity properties builder.
- AUNITS / AUPREC: format_angle() helper available (decimal degrees, DMS,
grad, rad). Callers that already format angular values via radians can
switch over without touching the helper signatures.
- INSUNITS + MEASUREMENT: xref's source INSUNITS is carried onto the
host BlockRecord.units during merge. commit_entity() then scales new
INSERTs so 1 source-unit maps to the host's INSUNITS length. When
either side is unitless (0) MEASUREMENT acts as the fallback
(0=Imperial / inches, 1=Metric / mm), matching AutoCAD's rule.

* io/xref.rs — replaced the 7-line "BlockRecord::is_loaded turned out to
be unreliable" rationale with a one-liner. The reverted experiment
lives in git history (e88a946, 0996b75).
* refedit::RefEditSession.insert_handle — set at construction but never
read; the "kept for future REFCLOSE DISCARD" TODO can come back via
git history when that feature lands.
* scene::mod — dropped the placeholder MeshModel re-export; nothing
outside `mesh_model` consumes the bare name and MeshLodSet is the
pipeline-facing type now.

* helpers::wcs_to_ucs — UCS inverse transform with zero call sites.
* scene::Scene::compute_and_set_world_offset — never called; the load

* tessellate::tessellate_mesh — never called; mesh tessellation goes
through `solid3d_tess`, not the truck Shell/Solid path.
* truck_tess::tess_to_mesh_model — orphaned with tessellate_mesh's
removal.
* MeshModel::WHITE / MeshModel::SELECTED — only used by the removed
tessellate_mesh.
* xattach::Step::FilePath variant — never constructed; XATTACH always
enters through `with_path` after the file picker. Replaced the Step

Xref work:
- merge_xref_into_block now copies the xref's layer / linetype / nested
block_record tables into the host under `{xref}|{name}` prefixes and
remaps entity references, so ByLayer/ByBlock resolution lands on the
right entry instead of falling back to WHITE + 1 px.
- expand_insert (and the explode fallback) detect xref BlockRecords by
flag and apply `fade_toward_bg(color, bg, 0.5)` to every emitted final
color (selection bypasses the fade). ExpandCtx propagates `is_xref` +
`bg_color` through nested expansions.
Block precision groundwork:
- BlockDefn gains `local_offset: [f64; 3]` set in build_defn from the
AABB centre of the defn's direct entities. tessellate_sub_local now
passes that offset to tessellate(), so LocalWire.points / fill_tris /
aabb_local / text_obb_local are stored in offset-frame f32 and don't
lose precision for distant content.
- emit_wire / emit_greeked_text / transform_tangent take the defn offset
and re-add it in f64 before composing with accum_xform. defn_aabb_
recursive transforms nested children from their offset frame into the
parent's. transform_offset_aabb_xy replaces transform_aabb_xy.

Empirically the DWG \"loaded\" bit doesn't track AutoCAD's XREF Manager
\"Loaded\"/\"Unloaded\" state reliably:
- File A: manager \"Loaded\", on-disk is_loaded = Some(true)
- File B: manager \"Loaded\", on-disk is_loaded = Some(false)
Same UI state, opposite bit values, so we were incorrectly skipping
xrefs the user wants loaded. Drop the `is_loaded == Some(false)` skip
and auto-resolve every xref again. The OOM problem this was meant to
mitigate is now addressed by the frustum culler, so loading more
xrefs no longer threatens the GPU budget.
The `BlockRecord::is_loaded` field + acadrust patch stay in place so
we can revisit once we identify the actual on-disk representation of
XREF→Unload (likely an XREF dependency record or
ACAD_XREF_PANEL_DATA xrecord).
Co-Authored-By: Claude Opus 4.7 <[email protected]>
When the host DWG marks an xref as Unloaded (via XREF→Unload in
AutoCAD), the user explicitly chose NOT to load that reference. We
were ignoring that and pulling the external file in anyway, which
on large drawings could push GPU memory past the device budget.
Bump the acadrust dep to the branch that exposes
`BlockRecord::is_loaded`, then short-circuit `resolve_xrefs` for
any entry with `is_loaded == Some(false)`. New `XrefStatus::Unloaded`
surfaces this in the command-line log so the user can see which
references were skipped (and can re-load them via the XREF dialog).
Co-Authored-By: Claude Opus 4.7 <[email protected]>
acadrust's DWG reader occasionally desynchronises on certain files
(observed on render.dwg: 1519 of 1763 LwPolylines arrived with non-unit
normals in the 1e200+ range and 100k phantom vertices). Tessellating
those entities allocates gigabytes and produces NaN-laden wires,
freezing the UI.
Add a pre-tessellation guard that scans freshly loaded documents and
drops any entity failing a cheap sanity check: non-unit normal,
non-finite or absurd coordinate, or vertex count above 100k. Count of
dropped entities is threaded through DerivedCaches and surfaced as a
warning in the command line so the user knows the file was patched up
on the way in.
Same file in DXF form parses cleanly (0 corrupt), so this is strictly
a DWG-path workaround until the upstream parser bug is fixed.
The new examples/inspect_polyline.rs is a one-off diagnostic that dumps
LwPolyline/Polyline2D/Polyline3D fields plus a corrupt-entity count;
useful for narrowing down the acadrust bug.

Big DWG/DXF files block the UI for seconds during parse + cache build,
leaving the user wondering whether the app froze. Split the file-open
flow into pick → load and show a modal overlay during the load: file
name, size, phase label (Reading / Parsing / Building caches /
Finalizing), animated indeterminate bar, and Cancel button.
Phase is tracked via a shared AtomicU8 written by the loader thread
and read by the overlay each frame. Cancel hides the overlay and
discards the result; the parser thread runs to completion in the
background since acadrust has no interrupt hook.

Implements a full in-app file browser window for Save As, replacing the
rfd dialog that could not expose the selected filter index on Linux.
The new chooser includes directory navigation, a scrollable file list,
filename input, and a format drop-down (DWG/DXF × 2018/2013/2010/2007/2004/2000/R14).
Co-Authored-By: Claude Sonnet 4.6 <[email protected]>
rfd does not expose the selected filter index, so the old DWG/DXF version
filters had no effect — every file was always saved as AC1032 (R2018).
Replace with a single custom iced Save As window that shows:
- File name text input
- Save-in folder input + Browse button (rfd folder picker)
- Format dropdown: DWG/DXF × 2018/2013/2010/2007/2004/2000/R14
- Save / Cancel buttons
The selected format is passed to save_as_version() which temporarily sets
doc.version before writing, so DwgWriter/DxfWriter emit the correct file
format. Also works in the unsaved-changes Save flow.

Two root causes prevented paper-space viewports from loading correctly:
1. acadrust's ViewportStatusFlags::from_bits() maps bit 0 → is_on, but
the real DXF/DWG spec uses bit 15 (0x8000) for "viewport on". Post-load
fixup in io/mod.rs now corrects this for both DXF and DWG files: when
bit 0 is clear but bit 15 is set, is_on is forced true and locked is
derived from bit 14 (0x4000).
2. Some DXF exporters write id=-1 for all viewport entities instead of the
standard id=1 (sheet) / id≥2 (user) convention. The is_user_viewport_id()
helper now treats any id ≠ 0 and ≠ 1 as a user viewport, covering both
the standard id≥2 and the non-standard id=-1 cases.

Polyline3D tessellation now separates spline-fit curve vertices (flag 8)
from frame control points (flag 16): the curve vertices form the rendered
wire while control points are exposed as key_vertices for snap. Polylines
without spline flags are unchanged.
DXF post-load fixup now also converts AttributeEntity and AttributeDefinition
rotation from degrees to radians (group code 50 bug), matching the existing
LinearDimension fix. Attribute text rendered from DXF files now has correct
orientation.
Co-Authored-By: Claude Sonnet 4.6 <[email protected]>
append_linear_dimension() applied the same perp offset to both d1 and d2,
but only d2 is guaranteed to be at the definition_point level; d1 must be
projected independently onto the dimension line, otherwise non-collinear
first/second points produce a parallelogram instead of a rectangle.
Fix: compute dim_line_pos = def.dot(perp) and project each endpoint
separately so the dimension line is always parallel to axis.
Additionally, the acadrust DXF reader stores LinearDimension.rotation from
group code 50 (degrees) without converting to radians, while DWG and our
own annotation commands store it in radians. Add a post-load fixup in
load_file() that converts the rotation to radians for DXF files so
tessellation can call cos/sin uniformly.
