Giant rasters (500 MB aerial/GIS TIFFs) decoded whole: multiple GB of
RGBA on a wasm heap is tab death, and even desktop silently failed
past the image crate's 512 MiB default allocation cap. Decoding now
probes the header for dimensions first and runs in tiers — full decode
under a per-target budget (512 MB wasm / 4 GB native, enforced through
the decoder's allocation limits so oversize fails fast instead of
ballooning), Lanczos3 downsample to a display cap (4096² wasm /
8192² native) when the decode fits but the buffer is oversized, and a
clear localized refusal naming the dimensions and the limit when it
cannot. The probed source dimensions stay the entity's sizing truth,
so a downsampled buffer never shrinks the on-paper footprint; PDF
export self-corrects (effective DPI derives from placement × stored
pixels). Refusals surface once per image through the pick, open, and
drop/re-resolve paths.
Decode coverage gains webp and gif (pure Rust in image 0.25 — no C,
no lockfile churn), with the attach picker and drop filters matching.
Remote http(s) raster references now fetch on web: CORS-classified
failures name CORS, HTTP errors name the status, bodies over 64 MB and
8 s deadlines are bounded, and fetched bytes join the session source
registry (so ARCHIVE can package them and re-resolution reads cache).
Georgian and Armenian Noto subsets ship (generation blocks included),
so those scripts render instead of skipping; scripts still without
subsets remain silently skipped, unchanged.
(cherry picked from commit ca0d7b96)
Ported onto main (#1717 review): Armenian and Georgian take the script
indices after Lao, which main added meanwhile.
Full verification of the XREF/data/ARCHIVE/worker wave (three
reviewers, one forensic) found no blockers and no crossfire damage;
five majors and several minors are fixed here.
- ARCHIVE now packages XREFs: the bytes registry added by the same
commit is consulted (the in-code 'no xref store exists' comment was
false within the commit), and the drawing is packaged only after
the full save preparation — without it kernel solids shipped
without their ACIS data.
- PendingClose stores the stable tab id instead of a vector index:
the web save now completes asynchronously, and closing a lower tab
during the serialization window shifted indices — closing the WRONG
tab, or panicking on a stale one. All producers and consumers
resolve the id at use.
- The xref bytes registry is capped (6 entries, oldest evicted): every
open, drop, and pick registered full drawing bytes with no bound —
an OOM waiting to happen. Reopened recents register too, so any
entry path can serve as another drawing's xref.
- A re-picked data-link source with the same name but different bytes
no longer silently replaces the first (the browser hands back bare
names, so two same-named files collided and every reference read
the newer pick): the pick is refused and the user is told why.
- The unresolved-xref warning lists file names (what to drop on the
page), not internal block names; the ZIP writer refused the ZIP64
sentinel values (0xFFFF counts, 0xFFFFFFFF sizes/offsets) instead
of emitting archives that send strict readers hunting for a ZIP64
EOCD that is absent; docs note the worker-side saves.
Known follow-ups documented, not fixed here: the serde-skipped
ExtendedEntity/CadDocument raw bytes still drop on worker crossings
(needs codec accessors — upstream), and WBLOCK/SAVEALL/ARCHIVE
still serialize inline (the worker route is a small follow-up).
(cherry picked from commit 6f429f24)
Ported onto main (#1717 review): main already keys PendingClose by tab
id, so those hunks stay as on main; the ZIP64 guard is moot with the zip
crate; the unresolved-xref names split on both path separators, since
Path does not split Windows paths in the browser build.
The last four big web-vs-desktop gaps.
XREFs: XATTACH reads the picked drawing's bytes and registers them
name-keyed (the image/PDF-underlay pattern), pre-parses on the web
worker, and the commit merge produces the same xref block flow as
native. Opened drawings resolve xrefs from the registry (trailing-name
match) before cache build; unresolved references produce ONE warning
listing the names and the fix — drop the referenced files on the page
(drops and picker opens now register their bytes) and reopen or
XRELOAD. XRELOAD works off the registry on unsaved drawings too.
Data Link & Extraction: spreadsheet links read picked xlsx/csv bytes
(calamine from slices / CSV from string) through a session registry,
so preview, refresh, and table-insert work on web; extraction takes
external drawings via a multi-file picker parsed on the worker, and
outputs CSV/TXT/.dxex via download_bytes. The disabled 'Add folder'
button explains why.
ARCHIVE/ETRANSMIT: assembles the drawing plus registered images, PDF
underlays, and session plot tables into a ZIP delivered as
{stem}_transmit.zip; skipped dependencies are reported by name.
Save/autosave off the UI thread: the parse worker gains a serialize
action (protocol v5) — the document is prepared once on the main
thread (clone, styles, dimension bake), then the DWG/DXF writer pass,
the dominant cost, runs on the worker; any worker failure falls back
to inline serialization with the identical shared implementation.
The save path also clears the dirty flag only when the tab didn't
change mid-write, and the runtime-fields sidecar now carries
graphic_data, fixing a pre-existing loss of raw DWG round-trip bytes
on web-opened documents.
(cherry picked from commit 2e100634)
Ported onto main (#1717 review): the new ocs_save crate builds on the
pinned codec; the hand-written ZIP writer is replaced by the zip crate
already in the tree; ARCHIVE packs registered xref bytes too and
serializes document_for_save() like a web Save; the web save prepares
document_for_save() (prepare_document_for_save now takes the copy by
value, so no second clone); the wasm resolve_path consults the xref
registry, so every reference lookup — not just resolve — finds dropped
files; XRELOAD keeps main's undo, unload and stale-baseline handling;
native data extraction streams the source drawings one at a time.
A fresh web-vs-desktop audit found the remaining gaps; this closes the
top ten.
Raster images: IMAGE attach read the picked file via image::open on a
name-only path (dead on wasm), and raster references inside opened
drawings decoded the same way. Picked bytes are now registered in a
name-keyed store (the PDF-underlay pattern), decoding runs from memory,
and dropped .png/.jpg/.bmp/.tif files register by name so unresolved
references in opened drawings re-resolve and render (and export to PDF).
Command gaps fixed with the bytes-at-pick / download_bytes pattern:
- WBLOCK now downloads the extracted block instead of failing on fs.
- SAVEALL saves every dirty tab instead of printing a no-op message.
- SCRIPT picks and reads the .scr file through the browser picker.
- CENTERLTYPEFILE picks the .lin/.dnl file and populates from text.
- Custom .ctb tables picked on web now parse, register for the
session, appear in the plot dialog list, and apply (load_named
previously returned builtin-only on wasm).
- LAYTRANS 'Load standards file' parses the picked drawing on the
existing web worker.
- INSERT 'from file' in the block palette parses picked bytes and
feeds the shared import path.
Text fidelity: TTF-named styles rendered as thin stroke glyphs on web
because the font database was empty. Fetched Noto faces are now
registered into it with a family alias table (Arial, Times New Roman,
Cambria, ... -> Noto Sans/Serif), so those styles render filled, shape,
export to PDF as vector fills, and appear in the style picker.
ViewCube labels request semibold again on web.
docs/native-vs-web.md: the hatch and font rows were stale (both work on
web now), the GPU row claimed WebGPU is used where available (the
backend is pinned to OpenGL), and the parallelism row missed the parse
worker — all corrected.
(cherry picked from commit c643a10e)
Ported onto main (#1717 review): conflicts resolved toward main — the
font-file lookup, PDF searchable text, purge service, block palette and
plot-style copy stay as they are on main; the web pieces (font registry
and aliases, session plot styles, SCRIPT/SAVEALL/CENTERLTYPEFILE picks,
block-from-file on the web) are layered on top.
The web build had no autosave: on_autosave was a no-op and the
subscription was native-only. Both gates are gone; every savetime tick
now serializes each dirty tab (same pre-serialize sync as the web save
path, no thumbnail, serialized serially off the critical paint path)
into a dedicated opencadstudio-autosave OPFS directory, keyed by
drawing name, without touching the dirty flag, downloads, or recents.
On boot the web app scans that directory and offers any snapshot
newer than the last saved copy in a localized Recover Drawing modal
(Restore opens it as "name (recovered).dwg" through the standard
open pipeline; Discard removes it; Escape discards). Saving or
closing a drawing clears its snapshot; the boot scan also garbage-
collects stale entries. run_web now requests navigator.storage.persist
so settings and OPFS data survive browser eviction.
(cherry picked from commit 101d167ebc)
STLOUT/STEPOUT wrote via std::fs and IMPORTOBJ read via std::fs, all
of which fail on wasm32. The export pickers now mirror the PDF path
(pick_*_owned returns a name-only PathBuf; the browser download names
the file) and the write tail swaps fs::write for sys::download_bytes.
OBJ import reads the picked file's bytes directly, like the web open
picker.
Opening by drag-and-drop was dead on the web build: winit never emits
FileDropped there. A wasm-gated io::web_drop module installs DOM
dragover/drop listeners, filters .dwg/.dxf, reads the File bytes
async, and queues them; the existing 50 ms PollWebControl tick drains
the queue into the same open path the picker uses (progress overlay,
recovery, OPFS recent cache).
Also floors the model-space plot sheet: extents smaller than 10 mm
(or the 0x0 paper a fresh unsaved drawing carries) now fall back to
the standard sheet instead of producing a ~3 pt page.
(cherry picked from commit ad60be11ed)
A new drawing carries the visual styles the reference's new drawing has
in its visual style dictionary. -VIEW sEttings Visual style offers them
(2dWireframe as "2D Wireframe") and a saved view starts with the 2D
Wireframe style.

- refresh_associative_sweeps runs on every edit and scanned the xdata of
every entity; it now returns at once when no associative swept surface
exists (its application is not registered) and looks at surfaces only.
- An arc's end angle was raised by TAU in a loop, which never ends on a
huge angle from a damaged file; the sweep is taken with rem_euclid.
- The sweep DELOBJ test expected surface sweeps to delete their sources,
which #1663 changed on purpose: an associative surface keeps them.
- codec c9ffcac (opencadcodec #103) adds an explicit viewport-off bit: the
viewport on state is read with is_on() and set with turn_on()/turn_off()
everywhere, so a viewport the file marks off shows off and can be turned
back on from Properties.

MTEXT draws its stored text instead of re-evaluating fields on every
redraw. Fields update on their evaluation events as the reference does:
open (1), save (2, not autosave), plot (4) and REGEN/REGENALL (16), each
masked with the drawing's FIELDEVAL (variable dictionary, 0-31, with the
reference's prompt and message), and the new UPDATEFIELD command
(selection, attributes of selected block references, "N field(s)
found." / "N field(s) updated."). A Date field (on demand only) keeps
its value until UPDATEFIELD. The FIELDDISPLAY gray box now covers each
field's own glyphs, one box per line it spans, instead of the whole
text. Codec moved to the update_fields / field_spans revision.

The DXF reader keeps marker identities on the block record but never materializes the entities, so block_entity_handle/block_end_handle dangle after every DXF load (reopened baked *D dimension blocks hit this every time). Re-create missing sentinels at load finalize, reusing the file handle when free and minting otherwise. Idempotent and DWG-safe: loads whose markers already resolve are untouched. Pinned by dimlinear_survives_save_reload_with_baked_geometry.
#1585's field_dialog action stored any index it was given, and the dialog
indexes its category, case, size, named-type, formula, precision and plot
scale lists with them, so an out-of-range value panicked while drawing.
They are checked against the list lengths now. The hyperlink browse
button drew a glyph (…) that is tofu without the font, and two of the
new local_header_dates calls were mis-indented.

Bug:
The --serve automation loop (stdin/socket) and the MCP stdio loop read
input with unbounded read_line/lines. A single line over 64 MiB - a
huge paste or a hostile client - grows the buffer until the allocator
aborts, the same class of failure as the HTTP path, on the non-HTTP
transports.
Reproduce:
1. Start --serve on a socket (or the MCP server on stdio).
2. Send one 65 MiB line with no terminating newline anywhere in it.
3. Before: RSS grows to the full line, then "memory allocation failed"
(or a multi-second stall while the line is copied).
4. After: the read fails at the cap and the existing EOF arm closes the
connection/stdio promptly.
Fix:
New shared src/io/line_read.rs module: lines_capped(reader, 64 MiB)
yields Err for an over-cap line, which the serve and MCP loops already
treat as EOF/close. rest.rs was refactored onto the same helpers so the
cap logic lives in one place. A regression test streams a 65 MiB line
at the serve socket and asserts the connection ends without a response.
The loader added every catalog linetype to the drawing with its [shape]
and ["text"] elements stripped, and the renderer reads the drawing's
own definition first — so BATTING, ZIGZAG, PLANT, POINT1/2, DRAINAGE,
FENCELINE, TRACKS, GAS_LINE, HOT_WATER_SUPPLY drew as plain dashes (a
near-solid line), and a saved file carried no shapes either.
- populate_document_from_source now stores each shape / text on the
element it follows, with a shape-file STYLE (empty name, one per file)
and the named text style; values keep their written decimals.
- One table maps shape names to numbers per shape file: the standard
ltypeshp 130–134, the bundled catalog's own beyond them. The renderer
resolves stored numbers through it instead of a hard-coded list that
ignored which file a number belonged to.
- A drawing's copy stripped to exactly the catalog's dashes (as this
loader saved them) gets its shapes and text back on open.
- Opening completes the linetypes before the geometry is prepared, so
the first view already draws them.

opencadcodec a35f43e reads R13/R14 LAYER records as plottable, the root
cause #1507 worked around on load; drop the host-side correction. Its
tests stay and now cover the codec fix end to end. They wrote one temp
file per version and ran in parallel, so each test now gets its own.
Co-Authored-By: Claude Opus 5.5 <[email protected]>
The LAYER record only grew a plot flag in R2000: R13/R14 carry frozen,
off, frozen-in-new-viewport and locked as four separate bits and nothing
else, so the reader has no bit to read and leaves `is_plottable` at the
`false` it starts from. Every layer of such a drawing then read as "don't
plot", the plot pass dropped every wire, and PLOT, the preview and
QUICKPRINT all rendered a blank sheet while the drawing still looked right
on screen — display and plot visibility are separate flags, so nothing
about the drawing itself looked wrong.
Restore what the format means by default — a layer plots unless a file
says otherwise — for the two versions that carry the four-bit record, on
both load entry points (bytes and path). R2000 and later keep the flag the
file stores, so a genuinely unplottable layer (DEFPOINTS) stays unplottable.
Tests: an R14 DWG written and read back keeps every layer plottable, the
path-based entry point does the same for R13, a modern file keeps the flag
it stored, and an R14 drawing tessellating to wires that are all
plot_visible locks the whole chain that used to blank the page.
The codec and kernel repositories and crates are renamed opencadcodec and
opencadkernel. Inside OCS they are depended on under short keys, so code
reads `codec::`, `kernel::` and the new `graph::` (opencadgraph, the node
graph engine). File-format and protocol spellings stay as they were: the
ACIS product id `acadrust`, the ACADRUST_* switches and the plugin
version keys `acadrust_version` / `acadrust_source`.
A button left of MCP on the command line opens a translucent node graph
over the viewport, with a palette of object, input, math, logic, list,
text and geometry nodes added by click or drag. An object node owns
drawing entities and its rows are the Properties panel's own rows for
them: the single-object page is extracted from refresh_properties as
entity_property_sections, values use the control protocol's
property_json, and writes go through set_property_value with a property
target override, so the panel, MCP and the graph share one read/write
path. A list reaching an object row makes one entity per element. Each
graph action is one undo step; the canvas pans and zooms.

- `--export ... --target-version`, and explicit target_format /

- `audit` read op: dangling layers/blocks, duplicate handles, non-finite

- `save_verified`: writes the requested version from the same snapshot a
normal save writes, reopens it, checks the version and the entity

- ZOOM EXTENTS includes SDF text glyphs.
- Live MCP acceptance script and an optional reference-console audit

- The acadrust DXF reader has converted ATTRIB/ATTDEF rotation to radians

an empty name (also from #1391).

supply is now refused, through one resolve_linetype helper.

Opening a drawing that another program or machine holds without read
sharing used to fail with a raw OS error, and the memory-mapped fast
path could kill the process outright: a mapped file that shrinks
mid-parse (a writer saving over it) or a cloud placeholder that cannot
page in raises an in-page exception no Rust code can catch.
Read the DWG through a guarded fast path instead: mmap when possible,
and fall back to one in-memory snapshot read — opened with the most
permissive share mode Windows offers (FILE_SHARE_READ | WRITE |
DELETE) — whenever the map fails or an I/O error surfaces mid-parse.
A snapshot can never fault: a concurrent writer just ends the read
early. Sharing violations (os error 32/33) now answer with a message
that names the file and the remedy, and OneDrive-style placeholder
attributes skip mmap entirely.
Tables copied from other applications into the plot styles folder were
listed but refused on selection, showing as "missing" with the reason
lost on a console: the loader failed hard on a checksum or a text length
that did not add up and on any non-UTF-8 byte — and those files carry
their descriptions in Windows-1252.
- decompress_ctb reads the file as it is: a checksum or length mismatch is
reported and read past (a genuinely cut-off file is still an error), a
zlib stream with a bad trailer is retried as raw deflate, and text that
is not UTF-8 is read as Windows-1252 (pens and colours are numbers and
unaffected; other code pages only show wrong characters in descriptions).
- PlotStyleTable carries load_warnings; every load site reports them on the
command line, so a table that needed tolerance says so.
- load_named explains itself: a .stb name says named tables are not
supported yet, a .ctb missing from the folder says which folder to copy
it into (instead of "Unknown built-in plot style").
- The Plot dialog shows the reason under the Table row (style_error) —
from a selection, from a page setup that names a table, and from the
Load… picker, whose error used to be swallowed.
- A table picked with Load… from outside the plot styles folder is copied
into it (unless a file of that name is already there), so it is listed
from then on and page setups naming it resolve after a restart.
Tests: flipped checksum, text length off by one, a short payload field,
Windows-1252 descriptions, a truncated stream, .stb and missing names.

The plot dialog asks CUPS printers for their sheets and margins; on Windows
the query was a stub, so every printer showed the paper catalogue with
unverified margins. The driver is now asked the way the plot dialog expects:
- windows_media (compiled and tested everywhere): the three parallel
DeviceCapabilities tables (ids, sizes in tenths of a millimetre, 64-WCHAR
names) become one PrinterMedia per distinct size — a rotated or
borderless twin folds onto its sheet, catalogue sheets keep their name,
unknown sizes carry the driver's — with the device's margins on every
entry and the driver's default sheet found by id or by user size.
- print_to_printer (Windows): DeviceCapabilitiesW for the tables, the
default DEVMODE for the default sheet, one portrait printer DC for the
unprintable margins (physical offsets and extents, per device — a
documented approximation). The DEVMODE fetch is shared with the print
path (with_printer_devmode).
- A direct print now asks the driver for the plot's own sheet (by id, or
as a user-defined size), so an A3 plot prints on A3 rather than shrunk
into the driver's default; a driver that refuses the sheet is asked for
the orientation alone.
- The capability cache remembers printers that could not be asked, so a
slow failing query runs once per session, not on every dialog open.
- PRINTERS <name> reports a printer's sheets, margins and default sheet.
Tests: names (NUL trim, full slot, lossy), media folding and dropping,
default by id / user size / none, DC margins, paper id lookup.

On the web build, {"op":"open","path":…} resolves the name against the
browser's recent-files cache, so a file that is not already there cannot be
opened by the control channel. Accept {"op":"open","name":…,
"data_base64":…} instead: the bytes go through the same parse, caching
and recovery path as a file chosen in the browser picker
(io::open_bytes_web, now shared with pick_and_load_web).
Native builds keep path-based open and reject data_base64 with
invalid_request.

load_file, used by headless export, xrefs and block import, finalizes a

Retaining a line's length added a P2PDistance constraint, whose gradient
divides by the current distance. For a zero-length line the solver got a NaN
Jacobian and its SVD fallback never returned, freezing the editor (e.g.
ECONSTRAINT on a line drawn by clicking one point twice). Hold coincident
endpoints together with per-axis differences instead.
Control-point splines read without knots are given a degree their control
points can carry (at most n - 1) and a clamped knot vector when a drawing
loads. Generating knots for fewer points than the degree underflowed during
DWG write: a panic in debug builds, an unbounded allocation in release, and
reachable from autosave. A lone control point with no knots or fit points is
purged as corrupt.

A page setup names its plotter, and AutoCAD looks that name up in its own
configurations: `DWG To PDF.pc3` for PDF output, the spooler name for a
system printer, `None` when nothing is assigned. Drawings saved here used
to carry the dialog's label ("Save to PDF file…"), so AutoCAD reported a
missing device on every layout plotted to PDF from Open CAD Studio.
- New `io::plot_device`: `PlotDevice { None, Pdf, Printer }` with AutoCAD's
spellings, a reader for stored names that keeps any plotter
configuration AutoCAD wrote (an HP `.pc3`, `DWF6 ePlot.pc3` — plotted to
PDF here but preserved for AutoCAD) and upgrades the legacy label.
- Printable areas: the PDF driver's margins per sheet variant (full bleed
edge to edge; standard / expand insets provisional until read off
AutoCAD's plotter configuration), and for CUPS printers the media and
margins the queue reports over IPP (`ipptool` `media-col-database`),
parsed once per printer and cached. Windows enumeration follows with
native GDI printing.
- Page setups now store the device in AutoCAD's spelling and the margins
of the chosen device/sheet, keeping the drawing's own values while
neither changed (AutoCAD's `PAPERUPDATE` behaviour). The paper-space
printable-area rectangle follows.
- Plot dialog: the default entry names the printer it resolves to; a
printer that answered lists its own sheets with a note; the media query
runs in the background and answers for a since-deselected printer are
dropped.
Tests: device names, stored-name resolution, PDF margin table, IPP media
parsing (sizes, margins, borderless folding, default sheet), PWG names,
plus dialog ↔ layout round-trips for PDF, legacy label, preserved plotter
configuration, sheet change → margins, and printer selection.

AutoCAD stores a layout's sheet as the plotter driver's canonical media
name (`ISO_A4_(210.00_x_297.00_MM)`, `ANSI_full_bleed_B_(11.00_x_17.00_Inches)`),
so a drawing saved here has to carry the same spelling for AutoCAD to find
the sheet in its DWG To PDF list, and a name that arrives from AutoCAD must
resolve to its dimensions and go back out untouched.
- New `io::paper_catalog` replaces the eight-entry `paper_sizes`: ISO A/B,
ANSI, ARCH (incl. E1) and JIS series with full-bleed / expand variants,
Letter / Legal / Tabloid, millimetre and inch units, a parser that
reconstructs any well-formed AutoCAD name (custom or driver-specific)
from its embedded dimensions, driver / legacy-config aliases (`A4`,
`Letter`, `Ledger`), and dimension matching that prefers the plain sheet.
- The Plot dialog stores the canonical name and shows the sheet as
`ISO A4 (210 × 297 mm)`; a sheet that only exists in the drawing is
listed first so it stays selectable.
- A sheet the user did not change keeps the drawing's own media name
(`paper_name_for_settings`), so a Windows printer's `A4` is not rewritten
to `ISO_A4_(…)` just by passing through the dialog.
- Drops the unused `PlotFormat` / `PlotOrientation` messages,
`paper_label_from_dims`, and three duplicated `match "A4" | …` tables.
Tests: catalogue spelling, parser round-trip, aliases, dimension matching,
display formatting, plus dialog ↔ layout round-trips for driver-named,
catalogue and unknown sheets.

- IMAGEEMBED: pack raster images into OLE2FRAME entities so a .dwg is
self-contained; 'Embed Image' entry in the XREF attach menu; control/MCP
op embed_image for external tools; dxf_name for OLE2FRAME queries.
- Scene: populate_images_from_document now rebuilds OLE2FRAME and PDF
underlay models too (they used to vanish after any XREF op).
- Printing: add PRINTER_ENUM_NETWORK pass when listing printers; GDI
spooler fallback (hayro raster at 300 DPI + StretchDIBits) for hosts
whose PDF handler registers no print verb; DEVMODE orientation with a
90-degree raster rotation fallback for v4 drivers; fix the fit-scale
precedence bug that printed blank pages.
- PDF export dialogs on Windows use the async file dialog so the native
overwrite confirmation no longer deadlocks the UI thread.
- Plot dialog: persist the chosen printer (saved on selection) and the
picked plot window across sessions; page setups with no device no
longer reset the output device.
- Community fonts: detect unresolvable .shx references on open and offer
a download from the repository's fonts/ folder (contribution guide in
fonts/README.md); custom font source URL setting for intranet font
servers; downloaded fonts resolve from the per-user fonts directory.
Path normalization with stable keys, relative/absolute/none pathtypes, wildcard matching, and reference entries with loaded, stale, missing, and unreferenced states.
Problem
The open guard rejects circles and arcs with a radius below 1e-10. A normal
open fails when a drawing contains one. The user gets the recovery prompt.
AutoCAD and nanoCAD open these drawings.
The check came from ace99541. Its comment says the tessellator cannot sample
a degenerate curve. That was true of truck's parameter_division. Commit
8c7ebdc9 removed truck. Commit 96be8214 made the kernel sample circles and
arcs by sweep angle with a floored segment count. The reason for the check
no longer exists.
Change
- Remove the near-zero radius check for circles and arcs.
- Keep the checks for non-finite values and radii above 1e10.
- Update the guard comments. The purge rejects parser desync. It does not
reject degenerate geometry. Be generous in what you accept and strict in
what you produce.
- Add tests: a zero radius passes the guard, an absurd radius does not.
- Change the automation purge test sample from radius 0 to radius 1e11.
Behavior
- Zero-radius circles and arcs load. They render as dots.
- Tessellation, hit testing, snapping, and hatch boundaries accept a zero
radius.
- The DXF writer does not change.
