Saving from a non-first paper layout still reopened on the first paper
tab: set_saved_active_layout only updated an existing CTAB entry, but
documents authored here never carried one, so CTAB was never written and
the reader fell back to $TILEMODE (which only records model-vs-paper) →
the first paper layout.
set_saved_active_layout now creates the CTAB DICTIONARYVAR under the root
named-object dictionary when it is absent (updating in place otherwise).
The root dictionary is taken from the header handle, or found by scanning
for the dictionary that holds ACAD_LAYOUT when a from-scratch document
has not populated the header handle yet. The writers persist it (they
serialize the document's objects and root-dictionary entries; the
root-dict rebuild in CadDocument::build() is not run on save).
Adds tests/active_space_roundtrip.rs, including a full DXF save→reload
round-trip asserting both $TILEMODE and CTAB survive.

Files saved while a paper layout was active reopened in Model space
because the loader hardcoded the current layout to "Model" and never
consulted the space recorded in the file.
The active space is a standard part of the format and acadrust already
round-trips it: $TILEMODE (header.show_model_space) for model-vs-paper,
and the CTAB current-tab variable for the exact layout name.
- Read: on open, pick the current layout from CTAB (when it names a
layout that exists), else $TILEMODE (Model, or the first paper layout).
- Write: Scene::sync_active_space_to_document() mirrors the active layout
back into the document (show_model_space + CTAB). It runs from
set_current_layout, so every active-layout change — the status-bar tab,
the Layout Manager's Set Current, create / rename / delete, and
undo/redo — keeps the document in sync for the next save.
$TILEMODE is the guaranteed mechanism (read and written for both DXF and
DWG); CTAB refines the exact tab when the variable is present.

Replace the custom in-app file-browser save dialog with the native OS
save dialog for choosing the destination path — folder browsing and
overwrite confirmation now come from the OS. A compact in-app modal
still selects the DWG/DXF format and version (a native dialog cannot
carry the version year) and appears only for Save As. Plain Save on an
unsaved drawing defaults to DWG 2018 with no picker. The file-name field
is shown only on web, where there is no native dialog.
Remove the hand-rolled directory listing, folder navigation, and
overwrite modal.

Generate a small wire-raster thumbnail when saving a DWG and embed it via
acadrust's preview API, so OCS drawings show a thumbnail in file browsers
and other CAD applications. Read the embedded preview back cheaply (file
header + preview bytes only, no full parse) to show a thumbnail per file
in the Start page's Recent Documents panel.
- io/thumbnail.rs: CPU rasterizer (current-layout wires -> BMP DIB) plus
a preview-only reader/decoder (BMP/PNG -> iced handle) for the Start
page.
- Embedded on save via stamp_thumbnail on both save paths.
- recent_thumbs cache filled on config load / recents change (never from
a view); a thumbnail is drawn beside each recent file.
Requires acadrust at 3111694 (preview read/write), already pinned in
Cargo.lock.

Pick a rectangular window in model space with the existing PLOTWINDOW command (now enabled in model space, previously paper-space only) and export it to a PDF at a chosen ISO paper size (A4-A0), orientation and scale (fit or ratio). The window is a hard clip boundary. Adds paper-size presets, a window-to-sheet transform, scale + clip support in the PDF exporter, and Page Setup controls (format/orientation/pick window).
An entity added via a plugin's AddEntity with a common.layer name that no
LAYER command ever created kept its layer in-session, but the DWG writer
resolves an unknown layer name to a NULL handle, so on reopen the entity
collapsed to layer 0.
Add a shared Scene::ensure_layer(name) that registers a missing layer with a
real handle (allocate_handle, per #67) and call it from add_entity and
update_entity. This covers the plugin AddEntity/UpdateEntity IPC and every
internal add path without a new IPC request. Existing/empty/"0" layers are
no-ops, so normal draw commands are unaffected.

A periodic subscription (every SAVETIME minutes — default 10, 0 disables)
writes a <name>.sv$ recovery copy of each dirty, already-saved drawing at its
own DWG version. Non-destructive: it never touches the original file or the
dirty flag, and skips unsaved (path-less) tabs. The SAVETIME command
sets/queries the interval and persists it. Recovery files (.sv$ and .bak) open
through the normal Open dialog — the loader detects DWG vs DXF from the leading
magic bytes, and a "Backup / Autosave" filter lists them.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
- Save: overwriting an existing file first copies it to a sibling <name>.bak
(default on; toggle with the ISAVEBAK command, persisted in settings).
- Open: .bak is a first-class type — the Open dialog lists it and the loader
detects DWG vs DXF from the file's leading magic bytes (the extension hides
the real format).
- File association registers .bak too, every launch (so users who associated
earlier get it automatically): Windows via the registry; Linux via a
high-priority shared-mime-info magic that resolves DWG/DXF content under the
.bak extension, with the generic *.bak glob claimed only once the app is the
default DWG handler — so it never hijacks other apps' backups.

Two in-canvas confirmations on the Save-As path:
- AEC/Civil drop warning: when the drawing carries unsupported AEC/Civil
(application) objects that survive only as verbatim source-version bytes,
saving to a different version or to DXF would silently drop them. The
dialog reports the count and offers "Save in source version" (keep) vs
"Save anyway" (drop). Same-version DWG saves are lossless and skip it.
- Overwrite confirmation: when the chosen filename already exists in the
target folder, "Replace" / "Cancel" before clobbering it.
The two chain (AEC first, then overwrite) via per-flow acknowledgement flags
reset whenever the Save dialog opens or closes. Detection is a new
io::dropped_on_save_count over the document's Unknown (raw-passthrough)
objects/entities.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
Civil3D/AEC objects (and raw MLEADER/Surface records, EED) can only be
written losslessly in their source DWG version. On save, fall back to the
source version when the chosen version is an incompatible encoding family
(acadrust CadDocument::has_version_locked_data), with a command-line
notice, across every save path (Save, Save As, save-before-close/quit)
via a shared dwg_save_version helper. Default the Save-As format dropdown
to the loaded file's version so a round-trip preserves it.
Picks up acadrust DWG-writer conformance fixes (3dbae05) so a Civil3D
R2004 drawing round-trips through OCS and opens in AutoCAD with no errors.

Re-pins acadrust to the dimension DXF round-trip fixes (rotation/text/oblique
degree<->radian units, radial/angular/ordinate group codes, ordinate X/Y bit)

lives in the acadrust DXF reader (keeping it here would double-convert).

Relocate three root-level modules into io/, where they belong by concern:
- update_check.rs -> io/update_check.rs (its own doc-comment notes it
mirrors how crate::io wraps blocking calls in async).
- patterns.rs, linetypes.rs -> io/ (standard resource catalogs parsed
from asset files and populated into the document — IO-shaped work).
Fix the moved files' include_str! paths (one level deeper), add the
mod declarations to io/mod.rs, drop them from lib.rs/main.rs, and
re-point all crate:: references to crate::io::. No behavior change.

A DWG DIMENSION references an anonymous *D<n> block that holds its drawn
geometry; AutoCAD-family readers render that block rather than re-deriving it
from the definition points. OCS re-tessellates dimensions for display and never
materialises the block, so on save a created dimension goes out referencing a
block that doesn't exist and the writer emits a null block handle. Strict
readers (DWG TrueView, QCAD) then drop the dimension or demand a recovery, and
lenient ones (BricsCAD) regenerate it at a different position.
Add bake_dimension_blocks(), called on the cloned document in
io::save_as_version / save_to_bytes, which builds a *D<n> anonymous block from
each block-less dimension's exploded geometry (extension lines + dimension line
+ measurement text) and points its block_name at it. Dimensions that already
own a block (imported, or copied via the *D-cloning copy path) are left
untouched.
Verified end-to-end: before, AutoCAD/Civil 3D 2026 reads 0 dimensions from an
OCS-saved file; after baking it reads all of them.

Issue #170's fix added a "This PC" volumes root above the drive
letters on Windows. Generalize it so the Save As dialog can switch
volumes on every platform:
- parent_folder() now climbs the filesystem root into the volumes
list on all platforms (`/` -> Computer), not just Windows.
- available_drives() is platform-specific: Windows probes A:-Z:,
macOS lists `/` + /Volumes/*, Linux lists `/` + the removable
mounts under /run/media/$USER, /media/$USER and /mnt. Other Unix
and wasm fall back to `/`.
- drives_root_label() shows "This PC" on Windows, "Computer" elsewhere.
- read_dir_entries() lists the volumes at the drives root on every
platform.
Also gitignore the dist/ web build output so the wasm binary is never
committed by accident.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
The custom Save As dialog navigated up the tree solely via
`Path::parent()`, which returns `None` at a drive root (`C:\`).
Navigation therefore dead-ended on the starting volume, so other
drives and USB sticks were unreachable.
Add a synthetic Windows "This PC" drives root above the drive
letters. `parent_folder()` now climbs `…\sub → C:\ → This PC`, and
`read_dir_entries()` lists the available volumes (probed A:–Z: by
stat, no new dependency) when at that root. The dialog's up-button
and path bar route through the same helper and show "This PC".

Gate target-specific code so neither build warns about the other's items:
native-only helpers (view, window icon, file dialogs, file association, plugin
host/guard/registry, self-update) are cfg'd to non-wasm; the wasm-only font
fallback (script_of / cjk_lang / request) is cfg'd to wasm. Drop an unused mut,
allow the few genuinely-conditional dead items (mesh_click_hit, GPU layout
helpers, parity stubs), and gate the embedded PlotSettings-unrelated dead
constants. Both targets now build clean (only the unavoidable nom/quick-xml
future-incompat dependency notice remains).

Remove accidental dead code (unused imports, the superseded paste tool()
helper, a never-read TORIENT handles field, a duplicate let binding, an
unneeded mut) and mark intentional-but-unwired scaffolding with
allow(dead_code): the web-only save_to_bytes, the plugin loadable() probe,
the planned PICK_HIGHLIGHT colours, the DynFieldSpec label, and the layout
ribbon helpers. Native build is now warning-clean apart from the upstream
nom/quick-xml future-incompat notices.

The web save path discarded the chosen format version (`let _ = version`)
and `save_to_bytes` never applied it, so every browser download was
written at the document's default version (AC1032 / DWG 2018) regardless
of the format picked in the Save dialog. (#122)
Thread `version` into `save_to_bytes` and set `doc.version` there, the
byte-buffer counterpart to `save_as_version`. Saving as DWG 2013 now
writes an AC1027 file.

On the web, Save and Save As now open the in-app Save dialog (filename +
format) like the desktop, and the unsaved-changes prompt's Save routes
through it too — instead of an immediate rfd download. Confirm serializes
to bytes and downloads directly via a Blob + hidden `<a download>` click
(a user gesture), so there is no intermediate "click to download" link.
Replaces the rfd-based download_web / WebSaveResult round-trip with a
synchronous sys::download_bytes. Native save is unchanged.
Native + web build; 75 tests pass.

Wire up save for the web build:
- `io::save_to_bytes`: serialize a document to a byte buffer (DXF via
write_to_vec, DWG via write_to_writer over a Cursor).
- `io::download_web`: browser save dialog → write bytes (triggers a
download).
- Save and Save As on wasm both go through a new `web_save` helper:
serialize the active tab and offer a download (no persistent path or
in-app save dialog on the web). Format follows the tab name's
extension, defaulting to DWG. Result reported via `WebSaveResult`.
Native build + 75 tests unchanged.

Wire up file open for the web build:
- `io::pick_and_load_web`: browser file picker → read bytes → parse via
`load_bytes` → build caches, returning the same payload as the native
loader so it feeds the shared `Message::FileOpened` handler.
- `Message::OpenFile` cfg-dispatches: native picks a path then loads on a
worker thread; web picks + parses in one async step. The web branch also
sets `opening` (the handler drops results when no open is in progress).
- Disable the cosmic-text shaping / fallback paths on wasm: the web has no
system fonts, so cosmic-text panics with "no default font found". LFF
stroke fonts (embedded) still render; LFF-missing glyphs are skipped.
Native build + 75 tests unchanged. Hatches still don't draw on the web.

With the wasm bundle building, get it rendering in a browser:
- Enable iced `webgl` so wgpu uses WebGL2 where WebGPU is absent
(e.g. Firefox by default), and `fira-sans` so UI text has an
embedded font (the web has no system fonts) — without it every
label was blank.
- Replace `std::time::Instant` with `iced::time::Instant` (web-safe);
`Instant::now()` panics ("time not implemented") on wasm and crashed
at boot via the command line.
- Skip the batched-hatch pipeline on wasm: its bind group needs
vertex-stage storage buffers, which WebGL2 lacks (validation error
on "New drawing"). Fields become Option; upload/draw guard on them.
Hatches don't draw on the web for now; everything else does.
- Fix the trunk feature flag (`data-cargo-no-default-features`) and
ignore the `dist/` build output.
Native build + 75 tests unchanged.

Add a cross-platform `io::load_bytes(name, bytes)` that parses DWG/DXF
from an in-memory buffer via acadrust's stream readers (Cursor), picking
the format from the name's extension. This is the foundation for opening
files on the web, where the browser delivers bytes rather than a path.
Native keeps the streaming `load_file` (lower memory on large drawings);
both share the post-load fixups. Builds on native and wasm.

wasm32 has no threads, so rayon's global pool would panic at runtime.
Add `crate::par::prelude`: native re-exports `rayon::prelude`, wasm
provides sequential `std`-iterator equivalents (par_iter / into_par_iter
/ flat_map_iter over slices, Vec, HashMap, HashSet). All call sites now
`use crate::par::prelude::*;` instead of rayon directly.
- wire_gpu's rayon `reduce` (2-arg, no std equivalent) is cfg-split to
a sequential flat_map concat on wasm.
- rayon moves to a non-wasm target dependency.
Native still runs in parallel; all 75 tests pass. wasm bin compiles.

First step toward a web build: the library now compiles for
wasm32-unknown-unknown with --no-default-features.
- Add a `solid3d` feature (default on) gating truck-meshalgo /
truck-shapeops / lzma-sys. These pull vtkio → xz2 → lzma-sys (C),
which cannot cross-compile to wasm. Without the feature the 3-D
solid path (tessellation, booleans, ACIS import) becomes no-ops;
2-D CAD is unaffected. Native builds keep the feature by default.
- Move native-only crates (ureq, open) to non-wasm target deps and
add cfg shims: update-check is a no-op on wasm, and a new `sys`
module provides open_url + handle_path (rfd FileHandle → PathBuf;
synthesizes a name-based path on the web).
Native build + all 75 tests unchanged. Browser runtime wiring
(entry point, trunk, real file I/O) is a follow-up.

A RasterImage stores its path on the linked ImageDefinition, usually as the
original author's absolute path (e.g. a Windows/VMware share) that doesn't
exist locally, so the image silently failed to load. On open, resolve each
raster image: use the stored path if it exists, else fall back to the same
file name next to the drawing, and write the resolved path onto the entity.

On the first launch that hasn't answered it yet, the app shows a small
dialog offering to become the default handler for .dwg and .dxf files.
The choice is persisted (default_assoc_prompted) so the prompt never
reappears.
The platform plumbing lives in io/file_association.rs:
* Windows — opens the OS's own per-app default-programs dialog via
IApplicationAssociationRegistrationUI::LaunchAdvancedAssociationUI,
passing the "Open CAD Studio" RegisteredApplications name the MSI
registers. Modern Windows guards the actual default behind a
UserChoice hash, so this is the supported consent path.
* Linux — xdg-mime default against the installed .desktop file, whose
MimeType entries already cover image/vnd.dwg and image/vnd.dxf.
* macOS — LSSetDefaultRoleHandlerForContentType binds the DWG/DXF UTIs
declared in Info.plist to the app bundle id.
The work runs on a dedicated thread (the Windows dialog is modal) with
the result delivered back through a oneshot channel and surfaced in the
command line.

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

Phase 5.2. Time each open phase — parse, purge, derived-cache build on

breakdown line on open completion:
parse 1240ms · purge 80ms · caches 340ms · xref 60ms · total 1820ms

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

cache-handle walk in build_derived_caches. Two O(N) entity walks collapse
into one, with identical MSPACE-membership filtering preserved.

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

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).

rfd does not expose the selected filter index, so the old DWG/DXF version

- 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.

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.

Adds STEPOUT / STPOUT / EXPORTSTEP command that exports all tessellated
Solid3D / Region / Body meshes to an ISO 10303-21 (STEP AP203) file.
Each triangle is encoded as a minimal ADVANCED_FACE with a PLANE surface
and CLOSED_SHELL topology — sufficient for import into all major CAD systems.
A file-save dialog picks the output path; the command line reports success or
errors. Requires at least one tessellated solid in the drawing.
Closes ROADMAP 14.10.
