The text of a radius or diameter constraint sits on its dimension line,
which breaks around it, and no centre mark is drawn while that line is
there. Text that no longer fits inside moves beside the circle at the end
of a short leader that leaves the rim, elbows and hooks under the text,
with the arrowheads keeping the circle. A dynamic dimension now keeps
only its text at a constant screen size; arrowheads and extension lines
keep the style's size in drawing units.

The commands ask for the circle or arc themselves, report the measured
size, take a dimension line location and then the value or name and
value, creating a radius or diameter dimension as the constraint's
dynamic dimension with a radN/diaN parameter, refusing a second radial
constraint on the same object and any non-positive value.

Dynamic dimensions carry DIMEXO/DIMEXE/DIMASZ overrides in text-height
ratios, a two-line angular dimension draws extension lines only beyond
its sides, a selected dynamic angle shows triangle grips at the arc ends
with squares at the arc point and text, and the constraint dimension's
Properties follow the reference: kind titles, General before Constraint,
angular-precision Value and Measurement, drawn text position, reference
row order for Fit, Primary Units and Tolerances, and text/dimension line
alignment rows reading On as the aligned state.

Three-point angular dimensions take their sweep from the two rays and the
arc point (extension lines follow their own rays, straight and reflex
angles draw), dynamic angular dimensions store no text point so DIMTAD
places the text beside an unbroken arc, and dynamic dimensions carry a
DIMGAP override of a quarter text height.

DCANGULAR picks two lines, an arc or three points, takes the dimension
line location to choose the sector and the value or name, and creates the
dynamic two-line or three-point angular dimension driven by an angN
parameter. Reference messages for invalid, repeated and parallel sides,
existing names and invalid names; angle values display within one turn at
the angular precision; the first side (or vertex and first point) stays
when the value changes; the ribbon Dimensional panel follows the reference
order.

Infinite construction lines tessellated to a single unit stub at the base
point, which can never close a face (and overwrote the real wire segments),
so XLINEs were silently ignored by BOUNDARY. Clip unbounded curves to the
finite extents via Liang-Barsky; lines missing the geometry contribute
nothing. Same shared helper fixes RAYs.
Tests:
- xline_splits_rectangle_into_two_faces: 10x10 rect split in two
- ray_splits_rectangle_into_two_faces: upward ray splits in two
- xline_missing_the_geometry_contributes_no_face: distant xline is a no-op

single-slot Arc<[GlyphEntry]> memo on an 11-field key (hover/selection

#1418 added both as direct dependencies although each was already in the

code-page names. Cargo.toml keeps its dependency list.

Symmetric held the connecting direction perpendicular to the axis with
the kernel's angle-based Perpendicular, which locks its turn side at
construction: a point starting far from its mirror image had to swing
the pair through the axis direction, the residual wrapped, and the
solver stalled with the point unmoved. The perpendicularity is now the
projection of the pair onto the axis direction being zero, a polynomial
residual the solver follows from anywhere. Circle centers and ellipse
centers use the same equation. tests/parametric_constraints_solve.rs
symmetric_constraint_mirrors_one_circles_center_across_the_axis_line

- .github/workflows/ci.yml runs `cargo test --workspace --locked` on
pushes to main and on pull requests, with the Linux libraries the
release build installs. No formatter check: the tree is not
rustfmt-clean and stays that way.
- flake.nix, flake.lock and the direnv hook are removed. Nothing used
them, and their pinned dependency hashes were already stale after the
codec and kernel bumps.
- Under cfg(test) the "system" language resolves to en-US. The unit
tests compare English text through one process-wide loader, and every
apply_config of a default config asked for the system language, so a
Turkish locale failed 22 tests and parallel tests raced each other
through a language switch (the thickness-row test found its section
under one language and looked it up under another).
- The arc grip test follows #1352: the start, end and midpoint grips
drive the whole arc.

printpdf 0.9's `PdfSaveOptions::optimize` is a no-op — its `doc.compress()`
call is commented out — so every page's content stream (megabytes of vector
operators for a CAD sheet) was written uncompressed: a 16-sheet drawing set
exported as 280 MB. Serialise through `printpdf::to_lopdf_doc` and run
lopdf's `compress()` before writing; the same export is now 49 MB and
readers see ordinary FlateDecode streams.

Two layout defects that together broke every numbered note in a Chinese
drawing:
- Words were split on whitespace only, so a Chinese sentence — which has no
spaces — was one unbreakable word. When it did not fit after "7.<tab>" the
whole sentence dropped to the next line and still ran past the column.
Ideographic text may break between any two characters except before a
closing mark or after an opening one (the basic kinsoku rule); the atom
splitter now emits those break opportunities.
- `\pxi…,l…,r…,t…;` paragraph indents and tab stops are multiples of the
text height, and the first-line indent is relative to the left indent
(a hanging list is `i-1.5,l1.5`). They were applied as raw drawing units,
i.e. a fraction of a unit, so wrapped lines snapped back to the margin
and the number/tab column collapsed. Scale them by the entity height and
resolve the first line from the left indent.
Adds a layout test: a 40-ideograph paragraph in a 30-unit column wraps into
several lines, none wider than the column.

Point & line and 2Lines take a text baseline or an ellipse axis as the
line; a zero value folds the points onto the first one; 2Lines turns the
second line about its start. The Properties Constraint section edits
Constraint Form (Dynamic on the *ADSK_CONSTRAINTS layer, Annotational on
the current layer), Reference (driven constraint in parentheses whose
parameter follows the measurement) and Description (stored with the
parameter and the native variable). Dynamic dimensions keep a 12 px text
and 8 px arrows at any zoom, drop trailing zeros and show formulas as
`fx: len=d1*2`; the hidden constraints layer stays out of the layer lists.

Glyph quads bake the atlas UV of their tile. `grow_height` rescales every
cached entry's V and bumps the atlas generation, and the tessellation memo
folds that generation in — but the caches that hold finished wires do not:
the resident wire set is keyed by geometry epoch, block definitions by
block epoch, and a full build can grow the atlas part-way through (a CJK
sheet set bakes thousands of tiles on first sight). Text tessellated before
the growth then samples the wrong tiles for as long as those caches live,
which on a big drawing is forever: whole tables of scrambled glyphs, and
the block contents stayed scrambled even after a REGEN.
- `resident_wires_for` rebuilds (dropping the block definition cache) until
the atlas generation is stable across the pass.
- `Scene::update` compares the live generation with the one the scene's
caches were built against and bumps geometry once when it moved, so a
later growth (opening a layout, editing text) re-lays-out everything.

`shx.rs` only accepted the classic `AutoCAD-86 shapes 1.x` container, so
every modern Autodesk font (`txt.shx`, `simplex.shx`, `romans.shx`, … are
`unifont 1.0`) and every Asian big font (`chineset.shx`, `hztxt.shx`,
`bigfont.shx` — `bigfont 1.0`) was rejected and text fell back to the LFF
substitutes and TrueType fallback glyphs. Drawings authored with SHX big
fonts (the norm for Chinese / Japanese / Korean sheets) never showed their
real glyphs.
- Parse all three containers. Unifont glyphs are keyed by Unicode; big-font
glyphs by their double-byte code from a sparse hash table of
(code, length, offset) entries. Big fonts reference subshapes with a
two-byte `7, 0, hi, lo`.
- `bigfont_glyph` encodes a character with encoding_rs (Big5 / GBK /
Shift_JIS / EUC-KR, most likely first for the file name) and takes the
first code the font has.
- `Face::WithBig` pairs a style's big font with its primary face: full-width
characters come from the big font, everything else from the primary —
how a STYLE with a "Big Font" behaves in AutoCAD. `resolve_text_style`
resolves `big_font_file` like the primary (next to the drawing, then the
user fonts folder) and rides it along in the font name.
- The missing-fonts dialog lists unresolvable big fonts too.
Unit tests cover a synthetic big font (Big5 lookup, cap-height scaling, no
aliasing of unknown codes), a synthetic unifont, and the pairing.

DCFORM sets the annotational or dynamic form and continues into the
DIMCONSTRAINT option prompt, whose wording and last-used default match the
reference. -PARAMETERS manages parameters from the command line; a
double-clicked constraint dimension opens its value prompt. Dynamic
dimensions rescale on every camera change and their display overrides stay
out of the saved file. A driving dimension between an entity's own ends no
longer has its length retained, so a new value moves the second point along
the dimension axis; parameter edits hold the first constraint point.
Co-Authored-By: Claude Fable 5.1 <[email protected]>
DCALIGNED opens with `[Object/Point & line/2Lines] <Object>`. Point & line
asks `Specify constraint point or [Line] <Line>:` then `Select line:` (or the
line first and `Select constraint point:`), measures perpendicular to the
line from the constraint point to the line end nearest to it, and stores a
directed distance with the line as direction reference. 2Lines asks
`Select first line:` and `Select second line to make parallel:`, adds a
Parallel constraint solved with the first line pinned, then measures on the
solved geometry between the nearest ends. Unsupported line picks report the
reference's message; the same measurement again reports `The constraint
already exists on the selected objects.` and ends the command; an invalid
expression reports both reference lines and asks again.
The offered default and seeded expression carry twelve significant digits;
a typed value moves the second point (or the other object) while the first
point and its measured line stay, negative values keep their sign in the
parameter and use their magnitude, zero folds the points together, and the
dynamic dimension's origins follow every solve. The lock mark sits after the
text, a selected dynamic dimension shows triangle grips at its points and the
text square, and its Properties show the Constraint section (Name and
Expression editable) plus Text rotation.

Every dynamic dimension gets a DIMSCALE override for 12 px text, refreshed
per zoom band, at creation and after load. A SCALE/ROTATE of an entity whose
own end points a driving dimension measures now pins its second constraint
point so the dimension moves the first end, as the reference does.

When a text style's SHX / stroke font lacks a character, the glyph comes
from a system TrueType font through `ttf_glyph::fallback_glyph`. That
substitute was normalised to the Latin cap height (9 units = text height),
which is right for Latin, Greek or Cyrillic stand-ins but wrong for CJK:
an ideograph fills the whole em square, and 1 em is 1.3–1.5 cap heights in
every common CJK font (DFKai-SB has no OS/2 cap height at all, so it fell
to the 0.7 em guess). Every substituted Chinese character therefore came
out ~40 % taller and wider than the big font (`chineset.shx`, `hztxt.shx`,
…) the drawing was authored with, and whole lines of notes ran past their
frames.
A big font draws an ideograph one text height tall and one text height
wide, so size full-width / ideographic fallback glyphs by their em box
instead. Other scripts keep the cap-height normalisation. Real TrueType
styles (`Face::Ttf`, shaped runs) are unchanged.
Adds a unit test that a fallback `中` advances by about one text height and
its ink fits the text height (skipped on machines without a CJK font).

`viewport_content_wires` projects model-space wires into paper coordinates
for plotting: the points and the linetype stations are multiplied by the
viewport scale, but `world_width` (the band width of a wide polyline) was
copied unchanged. The PDF / print exporter strokes that band at
`world_width` in paper millimetres, so a 15-unit-wide bus bar seen through
a 1:100 viewport came out as a ~21 mm black blob instead of 0.15 mm, and
every single-line diagram sheet plotted as solid black shapes.
Scale `world_width` by the viewport scale alongside the points, and keep
the per-point taper widths in step (or drop them when clipping changed the
vertex count, so they cannot misalign). Negative (fixed pixel) and zero
(lineweight) widths are left untouched.
Adds a regression test that plots a 15-unit-wide polyline through a 1:10
viewport and expects a 1.5-unit band in the projected plot wires.

The dynamic dimension of a dimensional constraint is now linked in the
drawing file (AcDbAssocDependency + AcDbAssocDimDependencyBody on the
constraint node), reread on load, hidden by DCHIDE/DYNCONSTRAINTDISPLAY
and never plotted; it carries a lock mark before its text. New
CONSTRAINTNAMEFORMAT and DYNCONSTRAINTDISPLAY variables and the
DIMCONSTRAINT option front end. A transformed entity whose own end points
a driving dimension measures keeps only the first constraint point, so a
scaled line returns to its dimension value.

DCLINEAR, DCHORIZONTAL, DCVERTICAL and DCALIGNED follow the reference flow:
`Specify first constraint point or [Object] <Object>:`, `Specify second
constraint point:`, `Specify dimension line location:`, then `Dimension
text = …` and `Enter value or name and value <d1=100>:`. Linear reads
horizontal or vertical from the dimension line location the way a linear
dimension does; Object takes a line's, an arc's or a polyline segment's
ends. A miss reports `No valid constraint point found.` / `No object
found.` and asks again; another object type reports `Invalid selection for
Linear. Select a line, polyline segment or arc.`.
Each constraint creates a drawing parameter (`d1`, `d2`, …, or the typed
`name=expression`), drives the constraint through it, and draws a dynamic
dimension in constraint gray whose text follows CONSTRAINTNAMEFORMAT
(`d1=100.0000`); the dimension is associated with the constrained objects
and its text is refreshed after every solve. A typed value other than the
measured one moves the second point while the first stays, and so does a
later parameter edit. Deleting the constraint removes its dimension and,
when nothing else reads it, its parameter.

A fresh reference session shows the "=" bar of every object made equal
through Multiple right away; the earlier hidden state was not the rule.
Co-Authored-By: Claude Fable 5.1 <[email protected]>
A second object of the wrong kind (a circle after a line, a line after a
circle) or a pair that already carries Equal now reports and asks for the
second object again instead of ending the command. The mismatch message
names what the first object asks for — `Select a line segment, polyline
segment, text, MText, major or minor axis of ellipse or elliptical arc.`
after a length object, `Select a circle or arc.` after a radius object —
and the same-pick message carries the reference's double space.
Co-Authored-By: Claude Fable 5.1 <[email protected]>
- An object that carries several Equal relations shows a single "="
badge, as the reference does, instead of one stacked badge per relation.
- A pick made in the Multiple flow leaves its new constraint bar unshown
until the object is selected or bars are shown, matching the reference;
the single flow still shows the bar at once.
- A typed coordinate at the Fix `Select object:` prompt and at the
Horizontal/Vertical `Select an object or [2Points]` prompt picks the
object under that point, like a click, instead of being read as a point.

Follow-up to the block-attribute grips picked from #1386.
- Movability no longer includes the invisible flag: an attribute ATTMODE 2
displays is grippable, so the grip the display-aware list shows can be
dragged. The document-less grips() still skips invisible attributes,
since it cannot consult ATTMODE.
- The grip sits on the displayed attribute, which an annotative insert
scales about its insertion point; Scene::apply_grip now unscales the
dragged target the same way before the attribute stores it, so the grip
no longer jumps to twice the drag at scale 2.
Co-Authored-By: Claude Fable 5.1 <[email protected]>
Selecting a block showed one grip, at its insertion point, so there was
no handle to pick an attribute up by: an attribute could only be moved
by moving the whole block.
Give the INSERT one grip per attribute, taken from the attribute's own
`Grippable` implementation, at ids `1 + index`. A drag on one moves that
attribute alone, through the same `apply_grip` the attribute already has
(which carries `alignment_point` along, so non-left alignments stay put
relative to the text). Grip 0 keeps translating the block and every
attribute with it (#255).
A constant attribute belongs to the block definition and an invisible one
is not drawn, so neither offers a grip; a locked-position attribute
declines on its own.

(cherry picked from commit 7eb966f6a2)
An OTRACK crossing is the meeting of two tracking vectors, but
`OtrackHit` carried only the one a typed distance is measured along, so
the overlay had a single guide to draw. Snapping to the crossing of two
vectors worked and looked like an unexplained point on one line.
Carry the crossed ray out of `otrack_snap` as `OtrackHit::cross`, keep it
on the app beside `otrack_active`, and let the overlay take a list of
guides rather than one. `otrack_active` still drives typed-distance
entry on its own, so distance entry is unchanged.

`sample_entity_xy` walks a polyline's exploded segments and drops the
vertex each segment shares with the previous one. A segment whose curve
plane is upright — any non-horizontal run of a 3D polyline — has no XY
curve, so `entity_curve_xy` declines it and the segment samples to
nothing. With nothing accumulated yet, the seam test compared the two
empty ends as equal and then sliced the empty sample from index 1:
panicked at src/modules/draw/modify/trim.rs:3982:42:
range start index 1 out of range for slice of length 0
On the web build that panic unwinds through winit's event-loop runner
and leaves its state borrowed, which is the "RefCell already borrowed"
follow-on in the same report.
Skip an empty sample instead, which leaves the seam handling to the
segments that do have a plan-view shape.

- resolve_point, set_polyline_vertex and the solver's point_for_marker
treat the marker one past the last vertex of a closed polyline as
vertex 0, the way line_segment already did. Equal (#1366), the axis
pre-alignment (#1365) and the transform pin (#1361) address a picked
segment's end that way, so on the closing segment they either refused
the pick or pinned nothing.
- Page-setup dictionary keys compare case-insensitively: page_setup_save
