Add a searchable block palette with previews, file import, collision-safe nested definitions, and dependency/table-record import. Keep palette thumbnails current across drawing switches and block-definition edits.
When writing a hatched region with holes to DXF/DWG, every NaN-separated ring was created with BoundaryPath::external(), so consumers treated inner loops as outer islands instead of holes. Only the first (outer) ring should carry the external / outermost flags; hole rings are left unflagged. A picked big-minus-small hatch now persists with the small rectangle as a real hole.
Adds a regression test asserting only the first boundary path is flagged external.
The HATCH/GRADIENT/BOUNDARY "pick inside" mode returned the first outline containing the click point, so the result depended on draw order and any nested boundary was ignored. For a small rectangle inside a big one, clicking inside the small shape would hatch the whole big rectangle (or the small one, depending on which was drawn first), and clicking in the gap between them always hatched the full big rectangle with no hole.
Resolve the click against every enclosing outline and choose the smallest-area one as the fill. Any other outline fully contained by that ring but not containing the click point becomes a hole. The boundary is emitted as NaN-separated rings, which the GPU and CPU rasteriser already fill via even-odd, so pattern, solid, and gradient hatches all render the correct region (the small shape, or the big-minus-small ring) regardless of draw order. DXF export now writes one boundary path per ring so nested hatches persist with real holes.
The UCS Icon, Properties, File Tabs, and Layout Tabs buttons were highlighted unconditionally because their ids fell through to an active_tool equality check in is_active_tool, which activate_tool sets on every click and never clears. Each id is now mapped to its corresponding visibility flag (show_ucs_icon, show_properties, show_file_tabs, show_layout_tabs), and those flags are kept in sync from their toggle handlers so the highlight reflects live state. The per-toggle booleans previously threaded through the render path are consolidated into a single ToggleState struct read from one place, so introducing a further toggle no longer requires changing every render-function signature and call site.
show_viewcube was excluded from render_signature, so toggling a static (cached) view produced an identical signature — the frame was skipped and the last GPU cube pixels stayed as stale cache. Add vp.show_viewcube to render_signature so the toggle invalidates the cache and re-renders, clearing the cube. The 2D overlay is iced UI and re-laid-out correctly, which is why only it hid.
NAVVCUBE is a command toggle, so it never set active_tool and is_active_tool never matched it. Add a show_viewcube flag to the ribbon (mirroring wireframe/ortho_mode) and special-case "NAVVCUBE" in is_active_tool to return the live show_viewcube state; ToggleViewCube now calls ribbon.set_viewcube.
Change CadModule::ribbon_groups() from -> Vec<RibbonGroup> to -> &[RibbonGroup],
backed by a per-module OnceLock cache. The ribbon group tree is static data
(&'static str, Copy enums) that was being fully reconstructed — Vecs, String
clones, enum discriminants — on every call, including all three per-frame
call sites (view(), dropdown_overlay(), style_combo_overlay()).
- 7 built-in modules + 2 plugin templates cache via function-local OnceLock.
Safe because each is a unit struct with exactly one instance per process
(plugins run in isolated child processes; see PluginProcess::spawn()).
- SharedCadModule avoids the static pattern entirely, storing groups in an
instance field (owned.rs).
- IPC runner converts &RibbonGroup -> OwnedRibbonGroup directly via new
From<&T> impls, avoiding an intermediate clone.
- render_small/render_large and the two make_tool_row closures now borrow
(&RibbonItem, &[ToolDef]) instead of taking ownership, so the view loop
doesn't need to clone items to satisfy the old by-value signatures.
- Various match-ergonomics deref fixes (*id, *default, *icon, etc.) from
the &RibbonItem pattern change.
printpdf's default = ["html"] pulled in azul-layout, rust-fontconfig,
kuchiki, xmlparser and their transitive trees (~40+ crates including
two with cdylib targets) — none of which are used by the project's
PDF export (only basic primitives like Mm, Line, Polygon, Rgb).
Also fixes a MinGW linker error (export ordinal too large: 100035)
triggered when ld.bfd tries to build a DLL for printpdf with >65535
exported symbols.
Consolidates 21 occurrences of identical Color literals scattered across widgets.rs and mod.rs into 9 named constants (COMBO_BG, COMBO_HOVER_BG, COMBO_OPEN_BG, COMBO_BORDER, COMBO_ACTIVE_BORDER, COMBO_ARROW, SWATCH_BORDER, TIP_BG, HIST_INACTIVE_BG). -85 net lines, zero behaviour change.
Section labels (Draw, Modify, Annotation, …) were left-aligned with a small padding. Set align_x(Center) on the parent column so the label container — still sized to its text width — is centred within the column, which itself remains sized by the tool buttons above. Sections keep their natural content-based width, no wasted space.
Colour-split MTEXT produces one outline wire per inline \C/\c override. At <5px zoom each outline independently emitted the full OBB greek rectangle — N overlapping boxes with last-colour-wins. Track last_lod_obb and skip duplicate substitutes.
Also corrects the fill-only LOD bypass: suppress fill-only wires at <5px instead of sending them unconditionally through emit_wire. The outline sibling's baseline or greek box suffices at sub-pixel zoom.
dimension.rs (x2), multileader.rs (x3), table.rs (x1) emit fill_tris
without a corresponding fill_tris_low. These will trip the debug_assert_eq!
added in the preceding commit when the entity appears inside a block
definition. Each site is marked with a FIXME referencing block_cache.rs:1397
and the correct fix pattern (split_ds on each vertex).
Three related bugs in tessellate_sub_local and expand_defn:
1. Wire folding lost per-segment colour. Multi-wire tessellator output
was concatenated (NaN-separated) into a single LocalWire using the
first wire's colour. Inline \C/\c MTEXT colour overrides inside block
definitions rendered in the entity colour instead of the override colour.
Fix: tessellate_sub_local returns Vec<LocalWire>; each wire from the
tessellator becomes its own LocalWire with its own colour.
2. fill_tris_low was never forwarded. The double-single precision path
was silently degraded on cached wires. Fix: fill_tris_low forwarded
from WireModel through to LocalWire and BatchEntry. debug_assert_eq!
added at emit site to catch future invariant violations.
3. Fill-only wires hit the text LOD ladder. MTEXT outline/fill pairs
produce separate LocalWires; the fill-only wire was routed through
emit_text_baseline/emit_greeked_text which ignore fill_tris (invisible
double-draw). Fix: is_fill_only field on LocalWire bypasses the LOD
ladder. Also fixes StyleKey::fill_only being hardcoded false at both
emit_wire call sites (latent batch misclassification).
resolve_font previously returned &str, passing raw stems like "arial" verbatim to Face::resolve. System font lookup requires the canonical family name ("Arial"), so inline \f/\F overrides from block-nested MTEXT were silently unresolvable and fell through to no geometry.
Change resolve_font to return Cow<'a, str>:
- no override -> Borrowed(base), zero allocation
- LFF built-in -> Borrowed(font), zero allocation
- system font resolved -> Owned(canonical), one allocation
- unresolvable -> Borrowed(base), falls back to style font
All 4 call sites updated to &font_name (&Cow<str> derefs to &str).
Adds two unit tests covering the fallback and TTF-stem-to-family-name paths. Adds integration test verifying block-nested MTEXT produces geometry and correctly separates outline/fill wires.
Text elements previously rendered as hollow wireframe outlines and sometimes
fell back to the wrong system font due to case-sensitive exact matching. Also,
the viewport background grid drew on top of solid entities.
Case-insensitive and partial-name fallback matching (e.g., mapping "arialn"
to "Arial Narrow") is now added to `sysfont::canonical_family_name`, ensuring
text resolves to the correct installed system font.
TrueType font contours are now triangulated into solid fills (`fill_tris`)
using `lyon_tessellation` in `ttf_glyph.rs`. To prevent the GPU from misclassifying
this 2D text as a 3D mesh (which broke flat shading), text tessellation splits
the output into separate outline and fill `WireModel`s.
The background grid is extracted from `SelectionCanvas` into `GridCanvas` and
moved beneath the 3D viewport to ensure proper layering. Finally, `DepthBiasState`
is enabled on all face/fill pipelines to apply a polygon offset, perfectly
resolving Z-fighting between coplanar wireframe lines and solid faces.
- Propagates commit status out of inline editors so commands know whether a real change occurred.
- Fixes TEXTEDIT's Undo step rolling back unrelated document actions when the user presses OK on empty/cleared existing MText.
- Custom recursive resolver ensures Leader entities trace back to their editable Text/MText annotations.
- Bypasses overly strict baseline field checks so TEXTEDIT can natively target and launch the inline editor on Leaders.
- Adds TEXTEDIT command to seamlessly edit annotation objects in-place.
- Matches industry-standard CAD tools' prompt behavior and "Current settings" banner logic.
- Implements the TEXTEDITMODE system variable (0/1) for Multiple vs Single editing modes.
- Enhances command lifecycle with CmdResult::SuspendForTextEdit and post_editor_closed hooks, allowing commands to cleanly pause and resume after external UI editors close.
