The rollover hit-test now sweeps wires, hatches, block-internal hatches
and shaded solid bodies, which is O(N) per cursor frame and was freezing
the crosshair on large drawings. Each idle move now clears the live
highlight and arms a dwell timer; HoverDwellTick runs the pick once the
cursor has been still for HOVER_DWELL_MS (120 ms), using the active
tile's bounds so the deferred pick matches the entity actually under
the cursor in tiled viewports.

A buggy external plugin that panicked anywhere — during load (version,
register, manifest), during ribbon build / dispatch, or inside an
interactive command (prompt, on_point, on_enter, on_object_pick) — took
the host down with it (#134). Run every cdylib entry point under
catch_unwind so the host stays up: the plugin's call is treated as
inert (load fails, dispatch returns "didn't handle it", interactive
hooks resolve to Cancel) and a "Plugin <hook> panicked: …" line lands
in the command line on the next tick. (#145)
Scope is Rust panics across the cdylib boundary, not genuine UB —
real isolation (segfault-proof) still requires out-of-process plugins.

The previous DIMTAD fix made every non-below value use the text-up side,
which broke DIMTAD=2 (Outside) — that should sit on the side farthest from
the measured points. Pass the DIMTAD value through instead of a below flag:
above (1) / JIS (3) / centred (0) use the text-up side, below (4) the
opposite, and outside (2) the away-from-object side. Tests cover above-up
and outside-away. (#144)
Co-Authored-By: Claude Opus 4.8 <[email protected]>
Dimension text vertical placement chose the perpendicular side away from the
measured points, so "Above" (DIMTAD 1) flipped to below whenever the
dimension line sat on the opposite side of the geometry. Place it on the side
the text top points to instead — the perpendicular of the dimension line
normalised to read left-to-right — independent of the object. (#144)

The point-in-polygon test in both hatch shaders walked edges
(v0,v1)…(vn-2,vn-1) but never the closing edge vn-1→v0, so an unclosed
boundary miscounted crossings and the fill bled outside the shape. SOLID
entities hit this — their four corners are not repeated — making color-wheel
fills spike past their bounds. Close each sub-loop (at NaN separators and at
the end); already-closed loops get a degenerate closing edge that crosses
nothing, so they're unaffected. (#140)

Ctrl+V was globally bound to the entity paste command, so it never pasted
into an open text editor, and even when routed there iced's clipboard read
is a no-op on the web. Route Ctrl+V to the focused editor and, on the web,
read the system clipboard via the browser's async Clipboard API (the
keypress is a user gesture, so the read is permitted):
- MText editor: insert at the caret (web + native).
- TEXT field: append on the web; native lets the text_input paste itself.
- No editor open: falls through to the entity paste command as before.

The web build has no system-font access, so CAD text in non-Latin scripts
(Cyrillic, Greek, CJK, …) rendered as nothing — build_fallback was a hard
None on wasm (#141). Instead, ship per-script Noto subsets under web/fonts
(one alphabet per file, SIL OFL 1.1) and fetch them lazily over HTTP the
first time a drawing uses that script, then outline glyphs with ttf-parser.
- web_font: Script enum + script_of (char → script font), a per-script
store with lazy fetch, and a pending queue drained by the app loop.
- CJK is split by language (chinese/japanese/korean). Han ideographs share
code points but differ by language, so the shared block is routed by the
document's $DWGCODEPAGE (932→JP, 949→KR, GB/936→CN); kana is always
Japanese, Hangul always Korean. Re-tessellates when the language changes.
- build_fallback (wasm) outlines from the fetched subset; clear_fallback_cache
lets glyphs that missed while a font was in flight reappear on load.
- PollWebFonts subscription (web only) + WebFontLoaded message drive fetches.
- Trunk copy-dir serves web/fonts; nothing is bundled into the native binary
(desktop keeps using system fonts).

The object-snap menu drew each mode's marker as a Unicode geometric glyph
(◻ △ ◯ …). The web build bundles only Fira Sans, which lacks them, so they
rendered as tofu boxes (#138). Add an SVG per snap mode under

tinted-SVG path the rest of the chrome uses — font-independent on every

The clap CLI work made boot() read crate::cli, but cli is cfg'd out on
wasm (the web build takes no args), so the wasm target failed to compile.
boot() is only used by the native iced::daemon run(); the web build boots
via boot_web(). Gate boot() with cfg(not(wasm32)) to match.

Replace the ad-hoc `--serve` arg sniff with a clap-parsed CLI:
- positional <file> to open at startup (also the OS file-association path)
- --new, --read-only, --backend, --safe-mode/--no-gpu
- --serve/--port (headless JSON automation, unchanged behaviour)
- --export IN OUT (headless format convert via the automation load/save infra)
- --script FILE (run command lines at startup)
- --log/RUST_LOG, plus --version/--help for free
GUI-only options pass to app::boot through a OnceLock config; read-only
gates the save paths. The web build skips parsing (no args).

A close signal can arrive while the app is backgrounded, leaving the
in-window unsaved-changes prompt unseen behind other windows. Funnel the
prompt opener through gain_focus + a Critical user-attention request so
the window raises (Windows/macOS/X11) or at least flags for attention
(Wayland via xdg_activation). Every unsaved-dialog caller shares this path.

The OCS arbitrary-axis algorithm crossed the normal with Wx=(1,0,0) in the
else branch, which collapses to zero for an X-aligned normal (e.g.
N=(-1,0,0)): the OCS axes became zero and every point mapped to the
origin. The resulting coincident points fed a NaN truck arc whose
parameter_division never converged, hanging the load on "Parsing
entities". Cross with Wz=(0,0,1) per the DXF spec. (#142)

ACIS stores no outer-vs-hole loop flag, so plane_face derives the outer
boundary as the largest-area loop and winds holes opposite. Document why
this is robust: try_attach_plane takes its plane normal from the first
(outer) wire, making the choice self-consistent without relying on the
analytic face normal. No behaviour change.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
A planar ACIS face lists its loops outer-first only by convention; a
pierced wall lists its window holes before the wall edge. plane_face
trusted loops[0] as the outer boundary and oriented every other loop
relative to it, so on a face with two or more holes one real hole wound
the same way as the true outer and truck's winding-number trim filled it
in. Select the outer boundary as the largest-area loop (it encloses the
rest) and wind all others opposite. (#123)

Ribbon layer dropdown rows were a single button, so a click on the
visible/freeze/lock icon fell through to the make-active handler instead
of toggling that state. Split the row: each icon is its own toggle
button, only the swatch+label selects the active layer. Toggle handlers
now resync the ribbon so the icon updates while the dropdown stays open.
Layer Manager columns are now sortable: clicking a header sorts by that
column, clicking again flips direction (SVG arrow indicator). Sort is
reapplied on every panel sync so it survives edits, preserves the
selection by name, and keeps the ribbon dropdown order in step.
Fixes#133

Block-internal entities ignored their own layer state: 2D subs were
only filtered by the invisible flag in the block-defn cache, and 3D
solids render through a separate mesh path that applied no layer filter
at all. Both now skip subs on off/frozen layers, matching top-level
entities. Caches rebuild on every toggle, so visibility updates live.
Fixes#133

Build pierced planar faces (a wall with a window opening) as truck faces
with inner hole boundaries: collect every face loop (outer + holes), wind
each hole opposite the outer so try_attach_plane cuts it, and let truck
triangulate. Drop the back-face cull on the solid-mesh pipelines so faces
show regardless of the import's winding (the shader already lights
two-sided). Relies on the acadrust SatLoop next_loop fix that makes hole
loops reachable. (#123)

Solids (meshes) now tint on rollover and selection: hover washes orange,
selection washes blue, with selection winning when both apply. Meshes
re-upload their tint when the highlight set changes, and the rollover pick
now also hits shaded solid bodies and hatches (mirroring the click-select
order: wire → hatch → block hatch → solid).
Wires get the same scheme: the selection xray overlay recolours selected
entities blue and the hovered entity orange (previously both blue). Drops
the now-unused highlight_handles union helper and its cache.

3D solid meshes inside block definitions were drawn once at block-local
coordinates without the INSERT transform, so a block authored in mm and
placed into a metre drawing at a 0.001 INSERT scale rendered ~1000x too
large. Split solid meshes into top-level (layout-owned, offset and drawn
flat) and block-definition (kept block-local) sets, and emit a transformed
instance of each block-def mesh per model-space INSERT, accumulating nested
transforms. Layout blocks are identified from the Layout objects'
block_record handles, since BlockRecord::is_layout() also flags ordinary
blocks in some files. (#123)

When drawing with Ortho (or Polar) on, a point that snapped to an object
(e.g. an Endpoint) was still pulled onto the ortho axis, so you couldn't
close a shape exactly on an existing vertex. Skip the ortho/polar
constraint while an object snap is locked, in both the preview and commit
paths. Grid snap is positional rather than an object snap, so it still
combines with ortho/polar. (#132)

Design note for a future migration: motivation, blockers (single-shader
rendering, VPORT rect vs split-tree fidelity, per-pane overlays), a phased

Thin vertical separators between every control in the top-left chip
(split / split / render-mode / grid / snap) for clearer grouping.

Move grid and grid-snap toggles off the status bar (and its customization
menu) into the top-left viewport chip, now a single container holding the
horizontal/vertical split buttons, render-mode picker, and grid/snap
toggles, sized to the render-mode picker. Add grid + magnet (snap) icons.
Render the grid per model tile from each tile's own grid_on, in its own
bounds and camera, instead of a single grid in the active tile. This stops
the grid flickering on/off as the cursor crosses panes or leaves the
viewport, and lets each pane show its own grid independently.

Make grid-snap a per-drawing view setting like grid visibility: drop it
from the persisted OSNAP set (settings.txt) and round-trip it through each
viewport's VPort SNAPMODE instead.
Grid display and grid-snap are now stored per model tile (like render
mode), written to and read from each tile's *Active VPort entry. The live
toggles mirror the active tile, and grid/snap are adopted from the active
viewport whenever it changes — on file load, tab switch, model-tile
activation, and new drawing — so they follow the active viewport rather
than a global preference.

Grid on/off now round-trips through the drawing's *Active VPort, so it is a
per-file view setting like every other CAD app treats it. Drop show_grid
from UserSettings (and its settings.txt key) and instead adopt the opened
file's saved grid_on on load. A legacy "grid=" line in an old settings file
is harmlessly ignored.

Mirror the in-app grid and grid-snap toggles (plus the adaptive grid
spacing) onto the *Active VPort entries so a saved DWG/DXF reflects what
the user actually has on, instead of always writing VPort defaults. The
flags are stamped when the toggles change and again before a save, and
carried across the camera-sync VPort rebuild so they survive an orbit/pan.
Only grid_on, snap_on and grid_spacing have an OCS counterpart; the other
VPort view fields (view twist, clip planes, lens length, etc.) have no
in-app source and stay at their faithful defaults.

acadrust's DWG VPORT writer hardcoded grid_on=true, so every file OCS saved
showed a phantom grid in other CAD apps (BricsCAD, DWG TrueView) that was
invisible and unselectable in OCS. The writer now emits the VPort struct's
real grid_on (default false for OCS, which never forced it on), so the
stray grid no longer appears. (#121)

Neutralise vendor references in comments to plain behavioural descriptions
(object acquisition / object snap). Remove the PICK_HIGHLIGHT and
PICK_HIGHLIGHT_DIM wire colours: their only consumer was the stripped

The dim-line break test used text_half + DIMGAP as its vertical
threshold, but DIMTAD 1/4 places the text exactly text_half + DIMGAP off
the line. The two terms cancel at the same DIMSCALE-scaled value, leaving
the comparison on the knife's edge — so a gap flickered into the line
depending on the DIMGAP/DIMSCALE combination. Drop DIMGAP from the
vertical threshold so above/below text stays strictly clear and the line
stays whole; centred text (DIMTAD 0) still breaks for the DIMTFILL
background. The horizontal half-width keeps DIMGAP so a real break clears
the text. (#94)

The polyline was only committed to the document on finish, so its partial
geometry produced no snap points — you could not snap to vertices already
placed. Publish it as a real LwPolyline at the second vertex and replace
its geometry in place as later vertices land, so it lives in the document
(and the snapper) throughout the draw.
New CmdResult::CommitLiveEntity / UpdateLiveEntity{finish} plus a
set_live_handle() hook let a command own an entity mid-run. The create
pushes a single undo snapshot; in-place updates push none, so the whole
object reverts as one unit. Updates preserve the entity's handle and
layer (a fresh built entity carries a NULL handle that would desync it
from the document map key and drop it from rendering). (#119)

The DYN angle box was placed at full cursor radius along the mid-angle
direction. With a near-zero sweep that direction collapses onto the
cursor ray, planting the box on top of the cursor / snap point and
hiding it. Pull the box back along the ray and offset it to the side
opposite the distance box so the snap point stays visible. (#124)

Object snaps were chosen purely by nearest screen distance, so the
"continuous" snaps that sit on the geometry (Nearest, Perpendicular)
were almost always closer than a discrete Endpoint/Midpoint/Center and
silently suppressed every other enabled snap. Selection is now
priority-then-distance: a higher-priority snap inside the aperture wins,
distance only breaks ties within a priority. (#118)
The aperture gate is `!(d2 < radius2)` rather than `d2 >= radius2` so a
NaN distance from degenerate geometry is rejected instead of passing the
gate and being chosen on rank alone (which fed a NaN point to the fill
tessellator and panicked).
Perpendicular now drops its foot from the command's drawing origin
(`Snapper::from_point`, set before each snap) instead of the cursor, so
the new segment is genuinely perpendicular to the target line rather than
just the nearest point on it.

Turn the ribbon Clipboard "Paste" button into a dropdown:
- Paste — existing pick-a-point paste.
- Paste to Original Coordinates — drops the clipboard at its source
coordinates with no prompt.
- Paste as Block — wraps the clipboard contents in a new block definition
and starts an interactive insert (prompts for the drop point, with the
geometry rubber-banding under the cursor).
Also fixes two bugs the new commands exposed:
- entities_centroid summed the NaN separator points wire models carry,
so the paste base point came out NaN; non-finite points are now
skipped. A NaN base previously froze block tessellation outright.
- PASTEORIG added clipboard entities with their original handles
(duplicates on same-document paste); it now goes through
add_entity_clone and merges referenced records like the other pastes.

`document.add_entity` only assigns the top-level handle, leaving inline
sub-entities that carry their own — INSERT attributes and 3D-polyline
vertices — with the source's handles. Copying such an entity therefore
produced duplicate handles in the document, which corrupts the saved DWG
so other CAD apps (QCAD, DWG TrueView) refuse to open it.
Add `Scene::add_entity_clone` / `reset_clone_subhandles`, which allocate
fresh handles for the entity and every inline sub-entity, and route all
duplication paths through it: COPY/ARRAY/MIRROR-copy (via copy_entities)
and clipboard paste. (#129)

Copy/paste between drawings dropped the entities' layer (and linetype /
text + dim style): the clipboard held only the entities, which reference
those records by name, so pasting into a drawing without a matching
record left the entity dangling on a non-existent layer. (#129)
Snapshot the referenced table records from the source drawing at copy
time (ClipboardDeps::capture) and, on paste, recreate any the target
drawing lacks with a fresh handle (merge_clipboard_deps). A record that
already exists by name in the target is left untouched — the target's
own definition wins; only missing ones are imported from the source.
Same-document pastes are unaffected (every record already exists).

Modals blocked the mouse but not the keyboard: keystrokes from the global
key subscription leaked past an open dialog into the command line and
fired as commands once it closed. Guard `update()` so that while a modal
is open, Escape closes it and every other keystroke-derived message
(command-line input/edit, F-key toggles, edit shortcuts, undo/redo) is
swallowed. A modal's own text fields keep working — they emit their own
messages, which are not in the blocked set. (#126)

The web save path discarded the chosen format version (`let _ = version`)

Dynamic-input value boxes, the prompt pill and the UCS axis labels are
