- DIMZIN now drives architectural feet/inch zero-suppression (modes 0-3)
inside format_architectural, threaded through format_with_unit (primary
and alternate units).
- DIMJUST 3 and 4 (over first / second extension) now rotate the text 90°
to read along the extension line, not just shift its position.
- DIMTAD 2 (outside) and 3 (JIS) resolve to the away-from-object side,
which equals "above" for 2-D linear dims; clarified in a comment.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
Two style settings were accepted by the editor but ignored by the
renderer:
- DIMTAD=4 (Below) placed text above the dimension line like DIMTAD=1;
the text is now offset to the opposite side.
- DIMTFILL=1 (drawing background) drew no fill; it now masks the geometry
behind the text with the background colour (DIMTFILL=2 already used
DIMTFILLCLR).
Verified the other enum settings render: DIMLUNIT/DIMFRAC unit formats,
DIMAUNIT/DIMADEC/DIMAZIN angular formats, DIMJUST positions,
DIMATFIT/DIMTMOVE fit, DIMTOLJ tolerance alignment, and the alternate-unit
/ zero-suppression families.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
The dimension style editor exposed every enum setting (DIMTAD, DIMJUST,
DIMLUNIT, DIMTMOVE, DIMATFIT, DIMTFILL, DIMFRAC, DIMAUNIT, DIMAZIN,
DIMALTU, DIMTOLJ, DIMARCSYM, and the zero-suppression family) as a raw
integer text box, forcing the user to type codes like "1". Replace them
with named pick_list dropdowns via an enum_field helper that maps the
stored code to a label and back. Numeric fields (sizes, colours,
decimals) and obsolete flags (DIMUNIT/DIMFIT) keep their text inputs.

When the dimension line is too short for the arrowheads, they are now
placed outside the extension lines (tip on the line, body outward) with a
short stub to sit on, instead of overlapping inside. DIMSOXD suppresses
those outer stubs. Ticks are unaffected (they always fit).
DIMATFIT's exact mode ordering and DIMUPT remain for a later pass.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
Centred dimension text that doesn't fit between the extension lines now
slides outside (text-outside placement), unless DIMTIX forces it to stay
inside. DIMTOFL is already satisfied for linear/aligned dims (their dim
line is always drawn between the extension points).
The remaining style flags are documented in place:
- DIMATFIT arrow-outside modes and DIMUPT need an arrow autofit pass.
- DIMTXTDIRECTION (RTL) needs single-line text direction support.
- DIMARCSYM / DIMJOGANG apply only to arc-length / jogged-radius dims,
which aren't shipped as entity variants.
- DIMUNIT is obsolete (superseded by DIMLUNIT).

Dimension text position ignored the style: the renderer returned the
saved text_middle_point whenever it was non-zero, which it always is for
app-created dims, so DIMTAD ("text over the dimension line" / ISO) and
friends had no effect — text could only be moved by grips.
Use the new acadrust text_user_positioned flag: when the text wasn't
user-placed, compute the position from the style (DIMTAD/DIMTVP/DIMJUST)
anchored on the dimension line (definition_point); when it was (grip drag
or properties edit, both now set the flag), keep the saved point.
Imported drawings keep their fidelity via the flag round-tripping through
DXF/DWG.
Also fixes linear/aligned text anchoring at the measured midpoint instead
of the actual dimension line.

Follow-up to the text/dimension fix: MultiLeader and Table were created
at their default style too. Their styles live in the objects dictionary,
so commit_entity_handle now resolves header.current_mleader_style_name /
current_table_style_name to the matching style object's handle and
assigns it, unless the command already set one or no such style exists.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
New annotation entities were created at the entity "Standard" default
instead of the document's current style, so making a style current had
no effect on creation.
- Text / MText: seed the new entity (and the MText editor preview) from
header.current_text_style_name.
- Dimension: commit_entity_handle fills the new dimension's style_name
from header.current_dimstyle_name, covering every dimension command
centrally.
Applied only when the entity is still at its default so an explicitly
styled entity is preserved. MLeader and Table styles need their style
tables modelled first and are left for follow-up.

A command step that takes both a point and option keywords (PLINE,
MLINE) returns true from wants_text_input to receive the keywords, but
CommandSubmit then routed the text only to on_text_input and, on a None
(unhandled) result, re-prompted instead of falling through. So with
dynamic input off, typed coordinates and a bare Enter were swallowed —
points couldn't be added by keyboard and the command couldn't be ended.
Fall through to the existing Enter / coordinate handling when
on_text_input doesn't consume the text. Coordinates (including @ and #
prefixes) and Enter now work in these steps with DYN both on and off;
commands that fully handle their text step still return Some and are
unaffected.

The Start (welcome) tab has no drawing, so commands like LINE dispatched

STRETCH edited geometry directly via document.get_entity_mut, which the

Making a layer current via the layer manager (LayerSetCurrent) or
LAYMCUR updated only the per-tab active_layer, not the document
header's current_layer_name/handle. The no-selection ribbon refresh
reads the header layer, so after the change an Esc (deselect ->
refresh_properties) snapped the active-layer dropdown back to the
stale header value ("0") even though new entities still used the
correct active layer. Mirror the change into the header in both paths,
matching the ribbon dropdown's own set-current path.

The last corner of a closed polyline joins its first (0) and last (n-1)
segments at vertex 0, but the corner fillet/chamfer used corner_idx
high%n (= n-1) and treated seg low as the "before" segment, so the
shared vertex and the before/after order were both wrong — producing a
fillet/chamfer at the wrong place. Detect the wrap pair and map
before_seg=n-1, after_seg=0, corner_idx=0. Applies to FILLET and
CHAMFER.

TrimCommand::on_entity_replaced never matched LwPolyline, so a trimmed
(closed or open) polyline kept a NULL handle in the command's entity
snapshot. A second pick on the same polyline then found nothing, so it
could not be trimmed more than once without restarting the command.
ExtendCommand already handled this case.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
Starting FILLET/CHAMFER from the ribbon left the command-line field
unfocused, so its Enter arrived as CommandFinalize and discarded a
typed option keyword ("R"/"D"), cancelling the command. Several
related dynamic-input issues surfaced from the same flow:
- CommandFinalize now forwards a non-empty command-line buffer through
CommandSubmit, so a typed keyword is handled the same whether the
command was started from the ribbon or the command line.
- sync_dyn_fields shows no coordinate box during an object-pick step
(needs_entity_pick / needs_structure_point_pick) — there is no point
to enter there, so typed keywords reach the command line cleanly.
- apply_cmd_result rebuilds the dynamic-input fields on NeedPoint, so a
step change (object pick -> radius entry) shows the matching box
immediately and typed digits land in it instead of the command line.
- Object-pick steps now draw a prompt-only hint pill at the cursor
(no input box).
- FILLET/CHAMFER remember the first pick across a mid-selection radius
or distance entry, resuming the second pick instead of restarting
selection.

Both the MSI and the portable build were missing Applications\OpenCADStudio.exe\
DefaultIcon, causing a blank generic icon in the "Open with" context-menu list
and the "Choose another app" picker.
- packaging/windows/main.wxs: add Applications\OpenCADStudio.exe\DefaultIcon
(+ FriendlyAppName, shell\open\command, SupportedTypes) to the
DefaultPrograms component for MSI installs (HKLM).
- src/io/file_association.rs: add DefaultIcon to the Applications\
OpenCADStudio.exe block written at runtime for portable builds (HKCU).
https://claude.ai/code/session_01DFVSKgViFaxEjZD2KsTdtt
The .desktop file used a named icon (Icon=io.github.HakanSeven12.OpenCadStudio)
but the icon file was never written to the XDG icon theme directory, so file
managers and the "Open with" picker fell back to a generic blank document icon.
install_icon() now writes assets/logo.svg (embedded at compile time) to
~/.local/share/icons/hicolor/scalable/apps/{APP_ID}.svg alongside the
.desktop file, and runs gtk-update-icon-cache so the change is picked up
immediately. The write is skipped when the on-disk file is already identical.

For MSI installs the installer already writes HKLM Capabilities +
RegisteredApplications, so the "Set as default" dialog works. For
portable .exe builds those registry keys are never created, so the
IApplicationAssociationRegistrationUI dialog silently does nothing.
register_handler() now also writes:
- HKCU\Software\Classes\Applications\OpenCADStudio.exe (Open-with list)
- HKCU\Software\Classes\OpenCADStudio.DWG / .DXF (ProgIDs + icon + open cmd)
- HKCU\Software\Classes\.dwg|.dxf\OpenWithProgids
- HKCU\Software\Open CAD Studio\Capabilities (AssociationToasts shown)
- HKCU\Software\RegisteredApplications (Windows Default Programs)
This makes the "Yes, set as default" button work correctly for portable
builds on all supported Windows versions.
https://claude.ai/code/session_01DFVSKgViFaxEjZD2KsTdtt
Installed builds already register a handler (MSI ProgIDs, the Linux
.desktop MimeType, the macOS Info.plist), but the portable .exe and the
AppImage register nothing, so they never appear in the OS "Open with"
list. Add a best-effort, idempotent runtime registration that runs
silently on a detached thread at startup:
* Windows — writes HKCU\Software\Classes\Applications\OpenCADStudio.exe
(open command + FriendlyAppName + SupportedTypes .dwg/.dxf), which is
what lists the exe in "Open with → Choose another app".
* Linux — writes a user-level .desktop pointing at the running binary
($APPIMAGE when set) and refreshes the desktop database. Skipped when
a system package already provides the desktop entry, so we never
shadow a distro install.
* macOS — no-op; .app bundles auto-register with LaunchServices.
Unlike the default-app prompt this changes no defaults and shows no UI;
it only makes the binary discoverable as a handler.
https://claude.ai/code/session_01DFVSKgViFaxEjZD2KsTdtt
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.

Switching to a paper layout used to hijack the ribbon with a contextual
"Layout" tab. Replace that with a reusable right-edge vertical toolbar:
a single centred column of icon buttons floated over the canvas, built
from a flat ToolDef list and dispatching through the existing
RibbonToolClick path (ui::side_toolbar). Paper space now shows Viewport /
Page Setup / Export PDF there and leaves the ribbon on the user's tab;
the contextual layout tab and its three auto-switch hooks are removed.
The toolbar is generic infrastructure for future context action sets.

The Annotate style dropdowns (text / dimension / multileader / table) and
the layer dropdown were hard-coded to "Standard" / "0" and never synced
from the opened document, so they showed placeholder values even with no
file open and stale values after closing one.
- Start the ribbon's style and layer lists empty instead of with a
placeholder entry.
- Sync the style dropdowns from the document on file open and on tab
new/switch/close (the layer sync already ran there).
- Guard sync_ribbon_layers / sync_ribbon_styles / sync_ribbon_from_selection
for the Start (welcome) tab so all three dropdowns stay empty there.
- When a style family is absent (e.g. no table/multileader styles), fall
back to empty rather than a non-existent "Standard".

Box selection is a two-click window (corner, corner): the first empty
click armed the box AND cleared the selection, and the box completion
cleared again before applying its hits — so a second box dropped
everything the first one picked. Stop clearing on the arming click and
make the completion accumulate like individual picks (#47): a plain box
or lasso adds, Shift+box/lasso removes the enclosed entities, an empty
box/lasso (or Esc) clears.

build_geos only turned Line/Arc/Circle/Ray/XLine/Ellipse/Spline into
cutting-edge geometry, so a polyline contributed no boundary and a line
could not be trimmed (or extended) against it — even though trimming the
polyline itself against lines already worked. Explode each polyline
(LwPolyline / Polyline / Polyline2D / Polyline3D) into its Line + Arc
segments and add them as boundaries, tagged with the polyline's handle so
the click-target self-exclusion still holds. Factored the per-entity Geo
build into geo_from_entity and exposed explode_polyline_segments.

The trim/extend hover preview (on_hover_entity) gets the cursor in
offset-relative space but compares it against WCS document entities and
returns WCS preview wires. On a drawing with a non-zero world_offset the
preview highlighted the wrong segment and the wires were shifted off the
geometry by the offset. Pass the world-offset-corrected click to
on_hover_entity and shift its returned wires back to the offset-relative
frame the renderer uses. Point-creation previews keep the local cursor.

The pick point handed to commands is in offset-relative (local) space,
matching the camera and point-creation commands. Entity-pick, tangent
and structure-pick handlers (TRIM / EXTEND / FILLET / OFFSET, …) instead
compare the click against WCS document entities, so on a drawing with a
non-zero world_offset (UTM-scale coordinates) the click landed ~1e6
units off the geometry — TRIM cut the wrong side or reported the click
as off the segment. Add world_offset back to the pick (model space only)
before passing it to those handlers, matching what the grip path already
does. Point-creation commands keep the local point unchanged.

ZOOM EXTENTS routes through fit_all, which built its bounds from the
wire set and returned early when there were none. A drawing of only 3D
solids has no wires, so ZOOM EXTENTS did nothing. Collect the
layout's mesh AABBs alongside the wires, keep going when only meshes
exist, and fold them into the fitted bounds.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
ZOOM EXTENTS / auto-fit derived the drawing bounds from wire AABBs and
tessellated key-vertices only. 3D solids (Solid3D/Region/Body) render as
meshes with an empty wire path, so they contributed nothing and a
drawing containing only solids zoomed to nothing. Fold each mesh's
offset-relative XY AABB into the extents on both the wire-cache and
tessellate-fallback paths.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
Solid3D / Region / Body have no truck wire conversion, so the wire path
fell through to the generic fallback, which returns a 1-unit placeholder
segment at the origin — a stray little line next to every 3D solid. Give
these types their own fallback that emits only the entity's pre-computed
edge wires (empty for binary SAB) plus an insertion snap, never the
placeholder.

ACIS keeps a solid's geometry in body-local space and records the world
placement in a `transform` record (3×3 affine + translation + scale).
The tessellator ignored it, so solids rendered at their local origin
instead of where the drawing puts them. Apply the body transform to the
mesh vertices (and rotate the normals) after tessellation.

A block reference with a visibility parameter now shows a triangular
lookup grip at the parameter point. Clicking it opens a dropdown of the
named states (current one marked); picking a state toggles which of the
anonymous block's members are visible and rebuilds, so the reference
shows the chosen profile instead of being frozen on the saved state.
The state list is data-driven (owned strings from the file) and applying
it mutates other entities (the anonymous block's members), so it stays
separate from the static GripMenuAction grip-menu: a dedicated
VisibilityPopup and an app-level apply path. The anonymous block is a
parallel-ordered clone of its definition, so a member visible in the
definition's state maps to the same index in the inserted block; the
chosen visibility flags round-trip through the DWG writer.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
A dynamic block with a visibility-state parameter stores the geometry
for every state in one anonymous block and marks all but the active
state's entities invisible. The block-cache builder tessellated every
sub-entity regardless, so a visibility block rendered all variants
stacked on top of each other instead of the one selected profile.
Skip invisible sub-entities in both the render pass and the precision-
offset centroid pass.

The GPU in_polygon ray-cast walks sequential boundary pairs and never
wraps last→first, so it needs an explicit closing vertex. The polygon
fill branch already appends one, but the rectangular branch returned a
bare 4-corner quad — the v3→v0 (left) edge went untested and the solid
mask bled past the boundary. Newly created wipeouts take this branch,
so the fill rendered wider than the clicked box while the border/grips
(drawn as wires) stayed correct. Repeat corner 0 to close the loop.

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.

Two follow-ups from the boundary-arc convention audit:
- ELLIPSE is a WCS entity in DXF (codes 10/11 are world coordinates,
unlike ARC/CIRCLE). The renderer ran center and major_axis through the
arbitrary-axis OCS, which misplaced any ellipse whose normal isn't Z-up
— e.g. the (0,0,-1) result of a mirrored-block explode. Read them as
WCS; pairs with acadrust 569bd4d, which stores WCS on its explode
paths. Z-up ellipses are unaffected (the conversion was an identity).
- The MIRROR command's hand-rolled hatch closure swapped boundary-arc
angles itself — only valid for ccw arcs and ignorant of the stored
mirrored-angle / wrap-encoded-sweep conventions. It now builds a
reflection Transform (new reflection_about_xy_line helper) and
delegates to acadrust's transform_hatch, the single source of truth
for those conventions. Covered by a Line→Arc→Line continuity + sweep
regression test.
Note: full effect of the ellipse change lands once the acadrust pin is
bumped to 569bd4d; until then only the (previously broken) non-Z-up
corner differs.

The MIRROR command's LwPolyline / Polyline2D closures reflected the
vertices but left the bulges untouched, so every curved segment of a
mirrored polyline bowed to the wrong side. A reflection reverses the
side a bulge arc bows to — negate it alongside the vertex reflection
(same convention acadrust applies on its reflecting-transform paths).
Co-Authored-By: Claude Opus 4.8 <[email protected]>
Hatches inside mirrored INSERTs (x_scale = -1, e.g. the *U blocks in
xref_Plan-Sade) drew some boundary arcs swept the wrong way, covering
huge complementary regions — in the pattern clip before EXPLODE, and in
both pattern and boundary wires after (the exploded entity bakes the
broken angles).
Root cause was in acadrust's transform_hatch, not the renderer: DXF
stores CW (ccw=false) boundary-arc angles MIRRORED (verified against
AutoCAD output by endpoint continuity — mirrored interpretation gives
Δ=0.0 against adjacent edges), and the transform stored geometric angles
after flipping the direction flag. The legacy (TAU-θ) sampling flip in
arc_signed_span is exactly right for file data and stays; its comment now
records the verification so the convention isn't "fixed" away again.

Grip markers drew visibly offset from the entity on large-coordinate
(UTM-scale) drawings: every Grippable impl cast the f64 entity coordinates
to f32 BEFORE the world-offset subtraction, and at 1e7 magnitude an f32
holds ~0.9 drawing units of rounding error. The wires subtract the offset
in f64 first (precision-preserving), so the grips landed up to ~1 unit
away from the geometry they belong to.
GripDef.world is now DVec3: producers fill it straight from the f64
entity data, refresh_selected_grips subtracts the world offset in f64,
and only the small offset-local result is cast to f32 for screen-space
projection (grips_to_screen / find_hit_grip) and drag state.

hit_test_wires got a cache keyed on geometry_epoch alone (462d9b4), but
the underlying wire set IS view-culled (wires_for_block culls to
view_world_aabb). After zoom-in + edit, the cache pinned the set culled
to that close-up view; zooming back out, blocks that had been off-screen
were missing from the pick set, so hover/selection stopped working on
them until the next geometry change.
Revert to the camera-keyed entity_wires_arc for picking — it re-culls
when the view changes. The actual 0.5.1 hover regression fix (hatch
rebuild/re-upload on rollover) stays.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
Selected hatches carry a tint (#71), so 0.5.1 keyed both the hatch model
cache and the static GPU buffer re-upload on `selection_generation`. But
that counter also bumps on hover, so moving the cursor over a new entity
rebuilt EVERY hatch model and re-uploaded the hatch + face3d buffers each
time — the large-file hover stutter introduced between 0.5.0 and 0.5.1.
The hatch tint depends only on the *selected set*, never on hover. Key
both on an order-independent signature of `selected` instead, so a
rollover keeps the caches warm; an actual select/deselect still rebuilds.
Also cache the picking wire set on `geometry_epoch` alone (separate from
the camera-keyed render cache) so a pan/zoom no longer re-tessellates the
whole un-culled model on the next mouse move.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
Two per-hover O(N) costs on big drawings, both keyed off the cursor:
- The selection/hover xray overlay rebuilt by scanning ALL wires and
string-parsing each `name` into a handle on every hover change. Index
handle → wire slots once per wire upload instead, so the overlay gathers
only the highlighted entity's wires (O(highlighted)).
- click_hit (runs on every mouse move) projected every vertex of every
wire to screen. In the flat top-down ortho view it now pre-rejects a
wire by its world-space AABB (four corners projected, so a Z-rotated
plan view is still correct) and only projects points for wires actually
near the cursor. Tilted/orbit views fall back to the full test, so no
pick is ever missed; covered by a unit test.

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).

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]>
Bump acadrust to pick up the new $CTABLESTYLE / $CMLEADERSTYLE header
variables, then on load seed the ribbon's active table style and the
tab's active multileader style from the document header so the ✓ marks
the style the file actually declares (DXF). Set Current writes the header
field as the round-trip source of truth, and the style-manager staging
snapshot now covers it. sync_ribbon_styles honours the active table style
instead of always falling back to the first one.
DWG still leaves these at "Standard" until acadrust parses them from the
binary header.
