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
Parsing + DerivedCaches construction now runs entirely in a dedicated
OS thread inside open_path(). FileOpened handler only assigns the
pre-built caches, keeping the UI thread free during file load.
- Add build_derived_caches(): parallel hatch + mesh tessellation via rayon
- Extend Message::FileOpened / open_path return type with DerivedCaches
- Drop populate_*_from_document() calls from FileOpened handler
- 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

LwPolyline PLINEGEN=0 (DXF default): emit SegmentedLines with NaN

GripApply::Absolute adds world_offset to convert local-space coordinates
back to DXF space for model-space entities. Paper-space entities (viewports,
etc.) use sheet mm coordinates with no world_offset, but the grip drag code
was unconditionally adding scene.world_offset — causing grips to jump by the
full model-space centroid offset (potentially hundreds of km for UTM drawings).
Now world_offset is only applied when current_layout == "Model".
Co-Authored-By: Claude Sonnet 4.6 <[email protected]>
Commands receive click coordinates in local space (DXF coords minus
world_offset) for camera precision. Without correction, entities were
placed world_offset away from the clicked position in existing drawings
that have a non-zero centroid (e.g. UTM-coordinate drawings).
Re-add world_offset via acadrust::Transform::from_translation (f64
precision) in commit_entity before the entity is inserted into the
DXF document. Paper-space entities are exempt as they use sheet coords.

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).
Co-Authored-By: Claude Sonnet 4.6 <[email protected]>
rfd does not expose the selected filter index, so the old DWG/DXF version
filters had no effect — every file was always saved as AC1032 (R2018).
Replace with a single custom iced Save As window that shows:
- 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.

- Grip points in paper space now use the 2-D linear to_px transform

- world_offset is no longer subtracted from paper-space entity grip
positions — paper-space coordinates are already unoffset (same rule
as wire tessellation in wires_for_block)

paper_limits() can return a non-zero origin (e.g. when min_limits has

The acadrust DWG reader never assigns a viewport id (always 0).
Some DXF exporters use id=-1 for all viewports. In both cases the
previous id > 1 check excluded every viewport from content rendering.
Replace is_user_viewport_id(id) with is_content_viewport(vp) that
uses a geometry heuristic for unknown ids (0 / negative):
- id=1 → always sheet viewport (excluded)
- id≥2 → always user viewport (included)
- id=0 or id<0 → sheet if center≈(0,0) AND scale≈1.0, else user
This allows DWG files and non-standard DXF files to display model
content inside their paper-space viewports and be entered via
double-click.
Co-Authored-By: Claude Sonnet 4.6 <[email protected]>
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.

Entity grips() return world-space coordinates (raw DXF values). After
the world_offset change the camera view_proj is in local space, so
projecting world-space grips through it gave wrong screen positions and
hit-test failures.
- refresh_selected_grips: subtract world_offset from every grip.world
so selected_grips are stored in local (camera) space
- Grip drag: cursor/snap positions are already local space; for
GripApply::Absolute add world_offset back before passing to entity
so entity coordinates stay in world space. Translate deltas are
identical in both spaces so no conversion is needed there.

Subtracts the DXF header extents centroid (world_offset) from all coordinates
in f64 BEFORE casting to f32. This eliminates the ~0.5 m ULP error that occurs
at 4,000,000 m UTM coordinates and caused geometry to disappear on zoom-out.
- Scene: adds world_offset field + compute_and_set_world_offset() method
- tessellate.rs: threads world_offset through all f64→f32 conversions
(legacy_geometry, dimension_geometry, solid_wire_fallback, multileader)
- truck_tess.rs: to_local() helper already in place from prior session
- mod.rs: tessellate_entity() and entity_aabb() apply world_offset
- update.rs: compute_and_set_world_offset() called after doc load
- cmd_result.rs / solid3d_cmds.rs: pass correct offset to truck tessellators

Add `aabb: [f32; 4]` field to WireModel (world-space 2-D bounding box).
In tessellate_entity() set each wire's AABB from e.as_entity().bounding_box()
via new entity_aabb() helper; Insert sub-entities each get their own AABB.
Preview/interim wires and any entity returning a zero-extent default box get
UNBOUNDED_AABB so they are never pre-rejected.
Replace the chord-sphere heuristic in Snapper::wire_in_range() with a proper
AABB vs snap-circle overlap test. The new check is four scalar comparisons and
correctly handles closed curves (circles, arcs) which the chord-sphere approach
had to special-case.

Option I: add per-viewport Arc wire cache so paper-space viewport rendering
no longer re-tessellates model content every frame.
Option J: hit_test_wires() returns Arc<Vec<WireModel>> — O(1) pointer copy
in model space instead of a full Vec clone on every mouse move during commands.
paper_canvas_hatches/wipeouts() now route through the epoch caches added in F.
Option K: add world_snap_r + wire_in_range() pre-check to Snapper::snap().
All Endpoint/Midpoint/Nearest/Perpendicular/Intersection loops skip wires
whose chord sphere is outside the snap circle using O(1) scalar comparisons,
eliminating O(entities × vertices) matrix multiply cost when zoomed in.

Add two complementary render caches that make mouse navigation essentially
free regardless of file size:
Option A – Wire tessellation cache: entity_wires_arc() caches the
tessellated Vec<WireModel> keyed by geometry_epoch and returns an Arc,
so navigation frames (no preview wires) incur zero Vec clones and zero
tessellation work. Primitive::wires changed to Arc<Vec<WireModel>>.
Option B – GPU buffer cache: Pipeline stores cached_epoch; prepare()
skips all upload_wires/hatches/images/meshes calls when the epoch is
unchanged, writing only the 192-byte camera uniform instead.
geometry_epoch is a process-wide AtomicU64 incremented by every Scene
mutation (add/erase entity, selection, layer visibility, layout switch,
populate_*, grip, transform, copy, clear, preview wires). Using a global
counter rather than a per-scene counter prevents two tabs that happen to
have the same local bump count from sharing a cached_epoch value, which
was causing the first file's geometry to remain on screen after opening a
second file.

White paper fill was calculated from entity bounding boxes (paper_entity_extents),

acadrust initialises every Layout with 12×9 imperial defaults; override
all non-Model layouts to 297×210mm in new_drawing() so the first paper
tab opens at A4 size, consistent with layouts added later.
Co-Authored-By: Claude Sonnet 4.6 <[email protected]>
- paper_entity_extents() computes the bounding box of actual DXF entities
so the white fill always matches the drawn title-block / frame borders,
regardless of whether Layout min/max_limits match entity positions
- Falls back to paper_limits() (→ A4 297×210) when layout has no entities
- Removed paper_boundary_wire: the white fill now acts as the visual paper
edge so the near-white wire (invisible on white) was redundant
- LayoutCreate sets limits to A4 landscape immediately after add_layout()
to override acadrust's imperial default (12×9)
Co-Authored-By: Claude Sonnet 4.6 <[email protected]>
- paper_limits() falls back to A4 landscape (297×210mm) even when no
Layout object exists in the document
- paper_bg_color default changed to white [1,1,1,1] (paper surface color)
- PaperCanvas::draw() fills canvas with dark desk color first, then draws
the paper area rectangle in paper_bg_color so the sheet is clearly
visible against the desk background
- view.rs container background uses the fixed desk color instead of
paper_bg_color so it no longer conflicts with the paper-surface color
- BACKGROUND RESET for paper space now resets to white instead of dark gray
- Removed unused PaperSheet variant, paper_sheet() constructor,
build_paper_sheet_primitive() and associated match arms (dead code
after 2D canvas replacement)

- viewport_screen_rect now mirrors PaperCanvas::draw()'s camera-based

Paper space is now rendered as a 2D vector canvas (iced::widget::canvas)
instead of a 3D shader widget. This allows direct interaction with
paper-space entities (title blocks, viewport borders, annotations)
without needing to enter MSPACE first.
Changes:
- src/scene/paper_canvas.rs: new PaperCanvas<'a> canvas::Program that
renders paper wires (with linetype dashes), solid/gradient hatch fills,
and wipeout backgrounds using the paper camera's orthographic transform.
- Scene: three new public helpers (paper_canvas_wires, paper_canvas_hatches,
paper_canvas_wipeouts) feed the canvas with the same data the old shader
used, including inactive viewport projections and interim/preview wires.
- view.rs: paper_canvas_view() now wraps PaperCanvas instead of
shader(ViewportPane::paper_sheet(…)). The PaperViewportPane 3D shader
overlay for the active MSPACE viewport is unchanged.

- Add orbit_active_viewport(), snap_active_viewport_to_angles(),
active_view_rotation_mat(), active_viewport_yaw_pitch() helpers so
navigation gestures modify the DXF viewport entity's view_direction
instead of the paper-space camera.
- Fix "already there → flip opposite" check: the previous code used
rot * Vec4::W (always (0,0,0,1) for a rotation matrix); now reads
(yaw, pitch) directly from camera_for_viewport() via the new helper.
- MSPACE right-drag orbit early-returns after writing the viewport
entity, preventing the paper-space camera from also being modified.

When a paper-space viewport is activated (double-click / MSPACE command),
it is now rendered through its own dedicated PaperViewportPipeline rather
than the CPU-projection approach used for inactive viewports.
Architecture:
- PaperSheet widget (full-canvas): renders paper entities + CPU-projected
content of all viewports *except* the active one.
- PaperViewportPane widget (Fixed w×h, positioned at viewport screen rect):
renders the active viewport with a true 3D camera derived from the
viewport's view_direction/view_target/view_height.
PaperViewportPipeline is a newtype of Pipeline. Having a distinct type
gives it its own Iced storage entry (keyed by TypeId), preventing the
shared prepare() overwrite that broke the earlier per-viewport approach.
Changes:
- render.rs: PaperViewportPipeline, PaperViewportPrimitive newtypes;
build_active_viewport_primitive(); build_paper_sheet_primitive() now
excludes active_viewport from CPU projection.
- viewport_pane.rs: PaperViewportPane<'a> with shader::Program impl.
- mod.rs: viewport_content_wires() gains exclude_vp parameter;
viewport_screen_rect() is no longer dead code.
- view.rs: paper_canvas_view() overlays PaperViewportPane when MSPACE
is active.

Iced 0.14 batches all shader prepare() calls before any render() calls.
Multiple ViewportPane widgets sharing the same Pipeline type overwrite
each other's GPU buffers, causing the PaperSheet layer (full-canvas) to
render the last viewport's model content — appearing full-screen.
Fix: paper_canvas_view() now renders a single full-canvas PaperSheet
widget. build_paper_sheet_primitive() is updated to include model-space
content projected through each viewport's view matrix (via
viewport_content_wires()), restoring the original working behaviour.
ViewportPane::Paper mode and viewport_screen_rect() are kept with
#[allow(dead_code)] — a per-viewport wgpu sub-renderer that accumulates
data across frames could revive them in the future.

- Remove Scene: shader::Program<Msg> impl; all GPU rendering now goes
through ViewportPane which supports three modes:
Model — full model-space view (unchanged behaviour)
PaperSheet — paper-space entities only, using the paper camera
Paper — model content through a specific viewport's own camera
- Add Scene helper methods (render.rs):
build_primitive / build_paper_sheet_primitive / build_viewport_primitive
update_viewcube_state / viewcube_mouse_interaction
- Add Scene helpers (mod.rs):
paper_sheet_wires() — paper entities without viewport projection
camera_for_viewport() — derive Camera from Viewport entity data
model_wires_for_viewport() — model wires filtered by per-viewport frozen layers
viewport_screen_rect() — paper-space → pixel rect mapping
- Add paper_canvas_view() in view.rs:
Stack of PaperSheet + one Paper widget per Viewport entity,
positioned with Space offsets from viewport_screen_rect()
- Update VIEWPORT_WIDGET_PLAN.md: mark Steps 1–4 done, document remaining work
