Phase 2.2. wires_for_block_culled re-tessellated every visible entity on
any geometry bump, so a single-entity edit cost a full model re-tess
(~30ms baseline after the block_epoch fix).
Add a per-entity memo (tess_memo: Handle -> Arc<Vec<WireModel>>) on the
culled Model render path. It's guarded by a hash of the tessellation
parameters (tol / view / anno / world_offset / bg / entered viewport); a
mismatch (zoom, layout switch) clears it. The render path now classifies
the visible set against the memo, materializes hits and tessellates only
the misses in parallel, then stores the misses back.
- bump_geometry clears the memo (structural change — safe default);
- incremental edits drop just the changed handle via mark_entity_dirty
and bump with bump_geometry_no_blocks: line commit (new handle is a
natural miss) and grip commit / Esc-cancel (mark the dragged handle).
The hit-test (view_aabb == None), paper and per-viewport paths bypass the
memo so their differing cull parameters don't thrash it. A single-entity
edit now skips the per-entity geometry math for the entire unchanged set;
the Vec assembly + batched-buffer upload stay O(N).

The block-definition tessellation cache (BlockCache::build — every block
defn) was keyed on geometry_epoch, so every edit rebuilt all block defns.
On a block-heavy drawing that turned the ~30ms visible-wire re-tess into a
~400ms spike at line-commit, grip first-move and grip release.
Key the block cache on a separate block_epoch. bump_geometry bumps both
geometry_epoch and block_epoch (safe default — xref, block create,
explode, REFCLOSE, undo, open all keep rebuilding blocks). Operations that
provably can't change a block definition now call bump_geometry_no_blocks,
which bumps only geometry_epoch so the visible wires re-tessellate against
the reused block cache:
- add_entity for a non-Insert/Block entity (line, arc, text, hatch, …) —
scene.add_entity only ever routes to model/paper space, never block
content;
- grip drag hide / commit / Esc-cancel — moving a top-level entity or an
insert never edits a block defn.
Line-commit and grip start/end drop from ~400ms to the ~30ms baseline.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
The grip drag mutates the document live (so grips and the properties panel
track the cursor), which meant Esc left the entity at its dragged position.
Back up the edited entity when the drag starts (the same first-move point
that hides it for the overlay preview) and, on Esc, restore that backup
before un-hiding and re-tessellating — reverting the entity to where it was
when the drag began. A normal release drops the backup and keeps the
dragged geometry.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
Phase 2.2 (partial). Dragging an entity's grip called scene.apply_grip on
every mouse move, which bumped geometry and re-tessellated the whole model
per move (plus an O(N) clone of every wire to exclude the edited one from
snapping). On a large drawing that's the 30ms->400ms spike, per frame, for
the duration of the drag.
apply_grip no longer bumps. The drag flow now:
- first move: hide the edited entity from the base tessellation (one
re-tess) and record it in grip_preview_handle;
- each move: apply the grip to the doc (no bump) and show the entity as a
one-entity overlay preview (set_preview_wires) — the base is a cache hit;
- commit on release / Esc: un-hide, drop the preview, one final re-tess.
Because the edited entity is hidden, it's already absent from
hit_test_wires, so snapping runs against the cached set directly — no
per-move clone and no self-snap. Two re-tessellations per drag instead of
one per move.

Now that selection/hover are decoupled from tessellation, highlighting the
entity under the cursor only refreshes the GPU xray overlay — no
re-tessellation — so a general rollover is cheap. On an idle ViewportMove
(no active command, no drag) hit-test at the cursor and set_hover_highlight
the result; clear it during commands/drags and on ViewportExit so it
doesn't stick over the ribbon. hit_test_wires is the cached entity-wire
Arc, so the per-move cost is just the existing click_hit projection — the
same the command-hover path already pays.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
Phase 5.3 (CPU tessellation slice). Add a `PERF` command that toggles an
overlay on the active viewport showing the cost of the most recent wire
re-tessellation: ms, wire count, geometry epoch. Anchored top-left via
position_canvas_overlay.
Timing is captured at the wire-cache miss paths (model_tile_wires_arc,
paper_sheet_wires_arc) and stored in Cells on Scene, read directly by the
UI view (Scene is single-threaded / Rc-based, so build_primitive and view
share a thread). Reads ~0 ms on a warm cache, so it isolates the exact
work a miss costs — the slice 2.2 / 3.1 / 3.3 each move, making them
PR-to-PR comparable.
GPU upload/draw/GPU-wait spans (need wgpu timestamp queries) remain open.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
Phase 5.2. Time each open phase — parse, purge, derived-cache build on
the loader thread, plus xref resolve on the UI thread — and emit a
breakdown line on open completion:
parse 1240ms · purge 80ms · caches 340ms · xref 60ms · total 1820ms
Makes open-time regressions (and the wins from 1.1 / 2.4) visible at a
glance. Timings ride back on DerivedCaches; total is wall time from the
Open click to post-xref.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
Phase 4.1. Handle / u64 keys dominate the hot maps (block_defn,
hatch / image / mesh caches, draw-depth map, viewport wire caches);
the default SipHash is wasted work on integer keys. Alias the std
types to rustc_hash::FxHashMap / FxHashSet crate-wide so every map and
set — including the cross-module draw-depth map shared between scene
and the GPU pipelines — uses the faster hasher consistently.
Mechanical: no behavioural change. Constructors moved from ::new() to
::default() (Fx variants carry no RandomState). Build + 13 tests green.

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
/ world_offset_from_centers; centroid accumulation now rides the existing
cache-handle walk in build_derived_caches. Two O(N) entity walks collapse
into one, with identical MSPACE-membership filtering preserved.

Row exit now clears the preview only when the highlight still points at
that row. Moving between rows can fire on_enter before the previous
row's on_exit, so the unconditional clear wiped a freshly highlighted
row (notably when returning to the first row). Guarding the clear fixes
the highlight not reappearing.

Add a scene hover_highlight handle that renders an entity with the
selection colour without joining the real selection. The cycling list
box sets it on row enter / clears on exit, so hovering a row glows the
matching object in the drawing.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
Replace the repeat-click cycling with a list box: when a click lands on
two or more overlapping objects (cycling on), a small list of the
candidates opens at the cursor. Picking a row adds that object to the
current selection (accumulate); clicking outside dismisses it. A single
object under the cursor falls through to the normal click.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
Add a click_hits_all hit-test and an SC pill that, when on, makes
repeated clicks at the same spot step through the overlapping objects
there (nearest first) instead of accumulating the selection. The whole
cycling path is gated behind the toggle, so default picking is unchanged
when it is off.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
Add a per-type selection filter to the scene: the FILTER pill opens a
checklist of the entity types in the layout, and unchecking a type
excludes it from interactive picking (click, box and lasso selection all
honour it). The pill lights up while any type is filtered out.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
When the QP pill is on, a compact floating panel appears at the canvas
top-left on selection, reusing the docked panel's editable section rows.
Toggleable from the status-bar customization menu.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
Add a transparency_enable uniform read by the wire shader: when the new
TPY pill is off, every line is forced opaque; when on, baked entity
transparency shows through. Toggling is a uniform write, no retessellate
(same mechanism as the lineweight-display toggle). Pill is toggleable
from the status-bar customization menu.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
Clicking the ISO pill now opens a small menu with Isolate Objects, Hide
Objects and End Isolation instead of ending isolation directly; rows
that don't apply (no selection / nothing hidden) are dimmed. The same
actions are added to the viewport right-click menu.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
Add a hidden-entity set to the scene that the tessellation visibility
test skips, so hidden objects neither render nor hit-test. New commands
ISOLATEOBJECTS (show only the selection), HIDEOBJECTS (hide the
selection) and UNISOLATEOBJECTS (restore). An ISO status pill lights up
while anything is hidden and restores everything on click.

Add a Units pill that shows the drawing's current INSUNITS value and
opens a picker to change it (Unitless, mm, cm, m, km, in, ft, mi, yd).
Toggleable from the status-bar customization menu like the other pills.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
Add a customization menu (far-right handle) that lists every status-bar
pill with a check mark; toggling a row shows or hides that pill, and the
choice persists across sessions in the config dir.
New pills:
- Coordinates: live cursor readout (re-adds the model-space world offset
so it shows true drawing coordinates), updated on every move rather
than only while a command is active.
- Clean Screen: hide the ribbon and side panels for a full canvas.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
Read the model-space annotation scale from the standard CANNOSCALE /
CANNOSCALEVALUE header variables instead of a user-variable hack, and
populate both the status-bar scale picker and the viewport Scale
property purely from the drawing's ACAD_SCALELIST — no built-in
fallback set. Xref-derived scales (`_XREF` suffix, `name|` prefix)
are filtered out so only the host drawing's own scales appear.
Bumps the patched acadrust to the commit that adds CANNOSCALE/
CANNOSCALEVALUE read/write.

The truck B-rep pipeline is Z-up (solids extrude/raise along Z, profile
wires convert pass-through), but two spots still assumed a Y-up world:
- REVOLVE swapped the axis/origin to (x, z, y), so the revolve axis sat
in the XZ plane while the profile sat in XY → wrong solid. Use the
axis/origin straight through.
- OBJ import kept Y-up coordinates as-is on the (now Z-up) viewport, so
imported meshes lay on their side. Rotate +90° about X on import
(positions + normals): (x, y, z) → (x, -z, y).
EXTRUDE (sweep along +Z) and the box/cylinder primitives were already
Z-up and unchanged.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
The drawing plane is world XY, but break, join, rectangular array, the
stretch/window move, the spline preview wire and several doc comments
still used the stale "Y-up XZ" mapping (world Z = DXF Y). That made
those commands operate against a constant-elevation axis: arc/circle/
line/spline break and join picked the wrong points, rectangular array
stepped rows along the Z (elevation) axis, window-stretch tested the
wrong window bound, and the spline wire drew in the wrong plane.
Map every drawing-plane coordinate through .y (elevation on .z),
matching the entity builders, the inquiry commands and the central
transform. Stale Y-up comments updated to avoid future confusion.

Creating a new MLeader/Table/MLine style (and a new PlotSettings) pulled
the document's next handle without advancing the counter, so two records
created in one session collided on the same handle and the second
overwrote the first. Use allocate_handle(), which reserves and advances.
Also bumps acadrust to pick up DXF annotative-flag persistence.

Table Style editor now exposes every TableStyle / RowCellStyle field:
- General: description, flow direction (Down/Up dropdown).
- Per cell: data type, unit type, format string, plus all six borders
(left/right/top/bottom/horizontal-inside/vertical-inside) with line
type (Single/Double), line weight, color (ACI), double-line spacing
and a visibility toggle.
Border type/visibility apply immediately; the numeric border fields and
data/unit/format are written by the existing "Apply cell" button.

MLeader Style editor now exposes every MultiLeaderStyle field: line
weight, line type / arrowhead block / text style / block-content blocks
(handle dropdowns from the document's tables), the four text attachments
+ attachment direction, the full block-content group (color, connection,
rotation, X/Y/Z scale, enable scale/rotation), leader & multileader draw
order, align space, and description.
Dimension Style editor adds the last uncovered DIMUNIT field.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
The bare STYLE command (sent by the Annotate-tab text-style combo's
"Manage…" button) fell into the LIST arm and only printed the style
list instead of opening the manager. Route no-arg STYLE / TEXTSTYLE to
the dialog, matching DIMSTYLE / TABLESTYLE / MLEADERSTYLE.

The enum/handle pickers in the MLeader, Table and Dimension style
editors used "Cycle" buttons, which were awkward. Replace them with
pick_list dropdowns:
- MLeader: path type, content type, text angle, text alignment.
- Table per-cell: alignment (9 anchors).
- Dimension: arrowhead blocks (DIMBLK/1/2/LDRBLK) and ext-line linetypes
(DIMLTYPE/LTEX1/LTEX2), options resolved from block_records/line_types.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
The arrowhead-block (DIMBLK/DIMBLK1/DIMBLK2/DIMLDRBLK) and ext-line
linetype (DIMLTYPE/DIMLTEX1/DIMLTEX2) Handle fields are now editable in
the Dimension Style manager. Each shows the resolved block-record /
linetype name and a Cycle button that advances through the available
records (NULL = Default arrowhead / ByBlock linetype). Edits bump
geometry so dimensions re-render with the new arrowheads/linetypes.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
Each row's RowCellStyle is now editable in the Table Style manager:
text style name, text height, text & fill color (ACI), background-fill
toggle, and alignment (cycle through the 9 anchor positions). Margin and
per-cell buffers load on open/select via a shared load_tablestyle_bufs;
edits write through objects.values_mut() and bump geometry so tables
using the style re-render.

New dedicated style-manager window for MultiLeaderStyle objects (the
existing mlstyle window edits MLineStyle, not multileader). Opened via
the MLEADERSTYLE command / ribbon manager entry.
Editable across Leader Format / Structure / Content sections:
- path/content/text-angle/text-alignment enums (cycle buttons)
- line & text color (ACI), arrowhead & break-gap sizes
- landing distance/gap, max points, segment angles, scale factor
- default text, text height
- enable landing/dogleg, text frame, text-always-left, annotative
New/Delete/Set-Current style management.

The Table Style editor's General fields are now editable: H/V cell margins
(buffers + Apply) and title/header row-suppressed toggles, loaded from the
selected style on select. Per-cell (Data/Header/Title) text/fill/border

Adds the remaining ~40 DIMSTYLE variables across the tabs (and a new
Alternate Units tab): dim/ext line colors+lineweights, fixed-length ext

vertical pos/fill/direction, fit options (DIMATFIT/DIMTIX/DIMSOXD/DIMTMOVE/
DIMUPT/DIMTOFL/DIMFIT), decimal separator, rounding, zero suppression,
fraction + angular units, alternate units, and tolerance vert-just/zero
suppression. Only the arrowhead-block / extension-line-linetype Handle

Reworks MLEADER text/leader geometry and grip editing, and aligns LEADER
to MLEADER's conventions (kept as separate entities).
Text & landing (render path):
- Text is side-anchored on the leader-facing edge and reads outward; the
side, alignment and the horizontal landing are recomputed every frame
from the text grip's position relative to the leader, so moving the
arrow or the text re-mirrors the whole layout and the landing stays
attached to the text's near edge.
- Fixes#49: text was centred on the leader endpoint regardless of side.
Grips:
- Text-location grip plus an MTEXT-style triangle wrap-width grip at the
box's far edge; dragging it sets the MText wrap width.
- Multifunction grip menu restored and made functional: leader-line
vertices offer Add Leader / Remove Leader (Add grabs the new arrow so it
follows the cursor — click places, Esc removes it); the text grip offers
Move Independent (text only) and Move with Leader (translates the whole
multileader via a move-all sentinel grip).
Arrows:
- LEADER and MLEADER arrowheads now render at the same size (text height),
matching previews.

The editor overlay's anchor was only clamped to the top/left edge, so an
MTEXT placed near the right/bottom of the viewport pushed the 640px panel
(and its toolbar buttons) off-screen where they were unclickable.
Both the MText editor and the single-line TEXT editor now receive the
viewport canvas size and clamp the anchor against the right/bottom edges
too, so the whole panel stays visible and usable wherever it is opened.
Fixes#52

Each model-space tile now carries its own visual style instead of one
global mode shared by every pane:
- ModelTile gains a `render_mode`; the active tile renders with the live
picker mode, inactive tiles keep their stored style, so changing one
tile no longer changes the others. Split inherits the source style.
- SetRenderMode writes only the active tile; switching the active tile
mirrors its style back into the tab (picker + live render).
- Persisted through the *Active VPORT entries (acadrust now round-trips
the render mode via DXF code 281 / DWG RC 281), restored on open for
both tiled and single-tile model layouts.
- Bump acadrust to pick up the VPORT render-mode field.

Two paper-space rendering fixes:
- The full-canvas sheet instance no longer draws model-block hatches/
wipeouts/images. Those belong inside the floating content viewports;
rendering them on the sheet let them bleed past the viewport borders
when model coords overlapped the paper area. The sheet now draws only
the paper block's own fills plus the synthetic white printable area.
- Pan/zoom/orbit inside a double-clicked floating viewport (MSPACE) now
re-culls and re-uploads the viewport's wire set. The per-viewport wire
cache key now hashes the viewport's own view (pan + zoom + orbit), and
the active-viewport pan/zoom/orbit handlers bump camera_generation so
the GPU re-uploads. Previously the stale frustum-culled subset stayed
on the GPU, so newly-revealed lines were invisible (hatches, uploaded
as the full set, still showed) until MSPACE was exited.

Switching between Model and a paper layout reset the camera to the last
saved state. The current camera was only written to the document on a
periodic tick, which may not have run since the last pan/zoom — so the
camera of the layout being left was lost. Sync it explicitly before
set_current_layout so returning restores where the user left off.

The overall "sheet" viewport now IS the paper view, so its own border
rectangle must not be drawn as an entity — filter it out of
paper_sheet_wires_arc (content viewport borders are kept).
Also update the doc comments that still referenced the removed
PaperCanvas widget / paper_canvas_wires to describe the GPU sheet path.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
Paper space now renders entirely through the unified GPU shader, exactly
like model space — there is no separate 2-D canvas. The full-canvas
top-locked "sheet" viewport draws the layout's entities, hatches,
wipeouts and images; the desk is the container background and the white
printable area is a synthetic solid hatch.
- The white sheet fill uses draw_depth -2.0 (entity fills/wires are in
the signed (-1, 1) range) so it is always strictly behind every object,
with a negligible z offset (BIAS 0.001) — no far-plane clipping.
- Delete src/scene/paper_canvas.rs (the PaperCanvas widget) and its dead
helpers (paper_canvas_wires / paper_sheet_wires / paper_canvas_cache).
paper_canvas_hatches / _wipeouts remain — still used by paper hit-test.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
Paper space now renders its sheet through the unified shader, the same
path as model space: a full-canvas "sheet" ViewportInstance draws the
layout's own entities + viewport borders + interim/preview wires, with a
camera locked to the top/plan orientation (paper is 2-D and never
orbits). Floating content viewports overlay it.
- PaperCanvas no longer draws entity wires (still paints the desk, sheet
and hatch/wipeout/image fills; full removal is the next step).
- Right-drag on the paper sheet no longer orbits the camera (it would
corrupt the frame and skew subsequent pans).
- Fix floating-viewport orbit oscillation: orbit_active_viewport wrote
view_direction.y negated while camera_for_viewport reads it un-negated,
so each drag step read back a Y-mirrored camera and flipped the model
between a rotation and its opposite every frame. Store eye directly,
matching snap_active_viewport_to_direction and the reader.

Persist the paper-space camera through the sheet viewport entity (which
round-trips natively in both DXF and DWG) instead of the
OpenCADStudio_Camera_* named-View side-channel:
- apply_sheet_viewport_camera reads the sheet viewport entity first; the
named View is only a backward-compat fallback for older files.
- sync_camera_to_document (paper) writes the camera only to the sheet
viewport entity. Model branch is unchanged.
- Add Scene::ensure_sheet_viewport: guarantee every paper layout has its
full-screen overall (id==1) viewport, creating one if a loaded file
lacks it; wired into layout enter and add_layout.
- Restore the owner-handle guard on the sheet-viewport finder so a
foreign layout's viewport can't be picked as the sheet viewport.

Single-click selection only tested wire-edge proximity, so clicking a
solid's face missed — only its thin projected edges were selectable.
Add mesh_click_hit: project each mesh triangle to screen and test the

and hatch hit-tests. Works for any meshed solid.

Rename the Home tab to "Draw" and add a Model tab beside it with two
groups:
- Model: BOX / CYLINDER / CONE / SPHERE / WEDGE / TORUS, placed with a
footprint + height. Each is built as a real ACIS Solid3D (acadrust
primitive builders) plus a truck B-rep, tessellated into the shaded
mesh pipeline, with edge wires for picking + wireframe.
- Design: UNION / SUBTRACT / INTERSECT via truck-shapeops.
A session-only Scene.model_solids cache holds each solid's truck B-rep
so the boolean tools can combine and chain them. Supersedes the old
command-line BOX/SPHERE/CYLINDER (insert::solid3d_cmds keeps EXTRUDE/
REVOLVE/SWEEP/LOFT).
Known limitations: booleans need solids created this session; curved
ACIS primitives render in-session but not after reload (the SAT
tessellator handles only planar caps); geometry assumes world_offset 0.

The annotation style combo renders its panel inline with no backdrop to

Route every text-bearing entity to an in-place editor instead of the
command line: a plain text box for single-line text (Text, attributes,
dimension override, tolerance) and the rich MText editor for MText /
MultiLeader. A Leader resolves to the entity it annotates.
- TEXT places a plain text box at the click; double-click edits in place.
- DDEDIT and double-click on any text entity open the matching editor.
- MLEADER places the leader then opens the MText editor on its content.
- LEADER follows the classic flow: points, Enter, then a linked empty
MText annotation opens in the editor; the leader's annotation_handle
links the pair so they edit/erase as a unit.
Adds shared field read/write helpers and a begin_text_edit router, plus
CommitAndEditText / CommitManyAndEditText results that commit an entity
and open its editor (commit_entity now returns the new handle).
