MultiLeader and Table were ignoring most of the styling and content
fields that the parser populated. Bring both up to file-driven render:
MultiLeader
- line_color: leader stroke / arrow colour with ByBlock/ByLayer fallback
- line_type_handle: dashed leader via line_types lookup by handle
- line_weight (ml.line_weight): per-leader pixel width override
- arrowhead_handle: arrow shape resolved through the dim arrow emitter
(Closed Filled / Open / Dot / Origin / Box / Datum / Tick / None)
- extend_leader_to_text: continue the leader past the landing to the
text insertion point
- text_angle_type: Horizontal forces 0, Optimized clamps to a readable
half-plane, ParallelToLastLeaderLine keeps the stored direction
- text_direction_negative: adds π to the rotation
- text_alignment: drives the horizontal anchor when more specific than
the context's text_attachment_point
- text_attachment_direction + text_top_attachment + text_bottom_attachment:
Vertical mode uses the top / bottom attachment values chosen from the
first root's direction.y sign
- has_block_contents + block_content_handle + block_content_location +
block_rotation + block_scale + block_content_color: synthesise an
Insert and explode it through the standard tessellator so block-
content MultiLeaders render their referenced block
- style_handle, arrowhead_handle, line_type_handle, text_style_handle,
block_content_handle, property_override_flags, text_align_in_ipe,
block_scale, block_rotation, extend_leader_to_text,
text_direction_negative, text_top_attachment, text_bottom_attachment
surfaced in the Properties panel
Table
- Per-cell borders: drop the always-grid pass, walk the cells and
emit each border honouring its `invisible` flag with dedup so shared
edges aren't doubled
- table_style_handle, block_record_handle, data_version, value_flags,
override_flag / override_border_* flags, break_options /
break_flow_direction / break_spacing, normal surfaced in the
Properties panel

Entity converters were casting WCS coordinates to f32 before the renderer
subtracted world_offset, which destroyed sub-unit precision on drawings
sitting at large coordinates (typical UTM-style CAD files). The multileader
case made it visible — glyphs warped under rotation — but every entity
that emits TruckObject::Lines/SegmentedLines/key_vertices/fill_tris was
affected.
Type changes (in src/scene/acad_to_truck.rs):
- TruckObject::Lines / SegmentedLines: Vec<[f32; 3]> → Vec<[f64; 3]>
- TruckEntity::key_vertices / fill_tris: f32 → f64
All ~17 producer files updated to keep WCS coordinates in f64 right up to
the TruckEntity boundary. The consumer in scene/tessellate.rs now performs
`(x - ox) as f32` (f64 subtract, then cast) for points, key_vertices, and
fill_tris — preserving precision near the camera origin even when the
drawing sits at million-unit coordinates.
catmull_rom_pts (multileader spline) is now f64; the scene path widens its
offset-relative f32 ctrl points to f64 around the call and narrows back at
the output.
Notes:
- Table layout still uses glam::Vec3 (f32) internally; widened to f64 only
at the TruckEntity boundary for type compatibility. Separate cleanup to
switch its internal math to f64 is tracked.
- snap_pts and tangent_geoms remain f32 — they are UI feedback (snap
candidates, tangent hints) and the precision is sufficient there.
Multileader text was emitted as a single literal stroke pass with no MText
code handling, no rotation, no attachment, no line breaks, no per-piece
color and bad f32 precision under world_offset. Two separate render paths
both had the same bug, and one was masking the fix in the other.
This rewrite, applied to both paths:
- Strips MText format codes (`{\fArial Black|b0|i0|c162|p34;...}`) so the
rendered text is the actual content, not the markup.
- Honors text_rotation (preferring text_direction so transforms survive),
text_attachment_point (Left/Center/Right horizontal anchor), and
text_left_attachment for vertical alignment via a shared
v_offset_for_attachment helper.
- Splits on \P/\n/\N and word-wraps to text_width.
- Applies line_spacing_factor with the same 5/3 × height convention as
MText.
- Resolves the text style via text_style_handle (fallback STANDARD).
- Applies ml.scale_factor everywhere (arrow size, dogleg length, text
height, text width). anno_scale is now only applied when
enable_annotation_scale is set.
- Splits the scene-level output into separate WireModels so leader,
text, frame and background fill each carry their own colour
(ctx.text_color, ml.text_frame, ctx.background_fill_color).
- Mirrors text_direction, base_direction and root.direction in
apply_transform so a mirrored multileader's text follows the geometry
instead of staying at its original rotation.
- Computes the text origin and frame corners in offset-relative f32
space — drawings sit at large absolute coordinates and casting to f32
before subtracting world_offset was wrecking the rotated sub-glyph
precision.
PolyfaceMesh and PolygonMesh were wireframe-only. They now render with
the same flat-color solid fill as Face3D entities.
- Add fill_tris: Vec<[f32;3]> to TruckEntity and WireModel
- PolyfaceMesh: fan-triangulate each face into fill_tris
- PolygonMesh: triangulate each grid quad into fill_tris
- tessellate.rs Lines branch: apply world_offset to fill_tris
- Face3DGpu::from_wires: collect fill_tris from all wires in addition
to Face3D key_vertices quads
- upload_face3d: pass all_wires so fill_tris are batched into one draw call
- Scale popup dropdown replaces cycle behavior; paper-space viewport scale
editable when a viewport is active/selected
- CANNOSCALE persisted via DXF $USERR1 (read on open, write on save)
- PSLTSCALE: linetype dash lengths scaled by viewport anno_scale so dashes
appear uniform physical size in paper space
- MultiLeader: arrow size, dogleg length, and text height scale with
anno_scale; leader line paths (world coords) stay fixed
- Leader: arrow size and hookline length scale with anno_scale; also
corrects world_offset subtraction that was previously deferred to the
TruckObject::Lines path

When path_type == Spline, the leader line is now tessellated as a
Catmull-Rom spline through the bend points (8 segments per span)
instead of connecting them with straight segments. Straight/Invisible
path types are unchanged. Key vertices and tangent geoms still use the
raw control points for snap and tangent snapping.
