world = insert_point + Rot * Scale * (P - base_point). Attribute placement, EXPLODE, XCLIP storage, REFEDIT's working copy, the UCS reframe of attributes and the dynamic-block visibility grip ignored the base point and were offset by Rot*Scale*base. They now share insert_transform_with_base. Creation stores a ZERO base and redefine resets it; a no-op redefine moves nothing; the Block Definition dialog prefills the base from the definition. XCLIP filters stored by older builds keep their old displacement.
- Pins: codec 8189f83, kernel a82f17d, graph d3558bb (all manifests and
the python plugin lock).
- MASSPROP reports volume, centroid, inertia, products, radii of
gyration and principal moments of 3D solids and bodies from their
B-rep (exact where analytic, else from a fine mesh).
- OFFSET of ellipses and splines through the kernel's curve offset.
- FILLET between circles, ellipses and splines through the kernel's
curve-curve fillet, trimming arcs and open splines to the tangents.
The kernel bump brings the DWG ACIS audit fixes: slices, booleans and
press/pull on cones, slanted cylinder sections, survey coordinates,
spline walls and touching parts.

flatten_plan 2,289 -> 1,098-1,144 us (-50..-52%); flatten_scene_apply 1,213 -> 789-813 us (-33..-35% vs baseline; -28.5% same-session O2-vs-O1, drift-corrected).
Pre-sizes collect/plan vectors and adds Scene::update_entities so FLATTEN issues one geometry bump per batch instead of per entity; single update_entity keeps its exact bump-per-call semantics.
Moves the flatten projection fns and command helpers into modules/draw/modify/flatten.rs (behavior unchanged) and adds flatten_plan / flatten_scene_apply to the COMMANDS suite.
The codec and kernel repositories and crates are renamed opencadcodec and
opencadkernel. Inside OCS they are depended on under short keys, so code
reads `codec::`, `kernel::` and the new `graph::` (opencadgraph, the node
graph engine). File-format and protocol spellings stay as they were: the
ACIS product id `acadrust`, the ACADRUST_* switches and the plugin
version keys `acadrust_version` / `acadrust_source`.
A button left of MCP on the command line opens a translucent node graph
over the viewport, with a palette of object, input, math, logic, list,
text and geometry nodes added by click or drag. An object node owns
drawing entities and its rows are the Properties panel's own rows for
them: the single-object page is extracted from refresh_properties as
entity_property_sections, values use the control protocol's
property_json, and writes go through set_property_value with a property
target override, so the panel, MCP and the graph share one read/write
path. A list reaching an object row makes one entity per element. Each
graph action is one undo step; the canvas pans and zooms.

Implement the complete Block Definition dialog window launched via BLOCK
and BMAKE commands, featuring standard CAD layout, workflows, and entity
creation pipelines.
- Dialog UI & Layout:
- 2-column compact CAD grid with synchronized vertical heights (580 × 390px).
- Editable combobox with existing block names, invalid character validation,
and inline redefinition badge.
- Multi-line text editor widget for block descriptions (replacing single-line input).
- Quick Select (QSELECT) button integration restoring dialog state upon completion.
- Confirmation guard when attempting to redefine an existing block definition.
- Centered radio buttons, clean coordinate inputs, and accessible keyboard shortcuts.
- Base Point & On-Screen Workflow:
- BlockOnScreenCommand strictly enforces prompt sequencing: Base point is
prompted before object selection.
- Dynamically recalculates world_to_block and block_to_world affine transforms
when base point is specified on-screen, preventing stale (0,0,0) normalization.
- Supports Retain, Convert to block (INSERT placement), and Delete modes.
- Explode Enforcement:
- Guarded EXPLODE command to prevent decomposing blocks flagged as non-explodable.
- Dynamic Themed Icons:
- Added pick_point.svg, select_objects.svg, quick_select.svg, and warning_triangle.svg.
- Routed all icons through the semantic theming engine so line work (#B4B6B9)
and accents (#6DB7ED) adapt automatically to the active theme.
- Tests:
- Added unit tests for retain/convert/delete modes, redefinition, explodable flag,
on-screen base point transform recalculation, and command sequencing.
Right-to-left line reordering walked each atom's byte range and sliced the
line at every byte, panicking when a neutral multi-byte character such as a
guillemet preceded the first strong character. Walk characters instead.
FIND/FINDALL located the REPLACE keyword in a Unicode-uppercased copy and
sliced the original with that offset; uppercasing can change byte length
(dotless i, ligatures). Uppercase ASCII only, which keeps offsets aligned.
FILLET and CHAMFER inline R/D shorthands now test the original text before
slicing past the first character.

Six one-shot alignment commands for the current selection —
ALIGNLEFT/ALIGNHCENTER/ALIGNRIGHT/ALIGNTOP/ALIGNVCENTER/ALIGNBOTTOM —
distinct from the existing point-picking ALIGN/ALIGN3D command: each
nudges every selected object (or complete group, via new
Scene::selected_object_units) so its bounding-box edge/center lines up
with the extreme edge/center already present in the selection, closer
to a word processor's "align objects" than AutoCAD's 3-point ALIGN.
Wired as plain one-click Tool entries in the Modify extension panel,
next to the existing ALIGN entry, matching that panel's flat-list
convention (no point prompts, so no dropdown submenu needed).

Sync current main and companion codec changes before preserving unsupported frame rows, rendering in the entity plane, and sharing final layout metrics with placement preview.
Avoid full document, cache, and GPU rebuilds for entity deltas so add, delete, history, selection, and live polyline edits stay responsive on large drawings.
PEDIT reworked around a mode machine:
- Picking a line/arc asks "Object is not a polyline. Turn it into one?
[Yes/No] <Y>" — Yes converts in place (arc keeps its bulge) and
editing continues on the result. Pickfirst: an already-selected
polyline skips the select step, a selected line/arc goes straight to
the convert prompt.
- Join gathers with the normal selection system (single picks AND
window/crossing boxes) and merges through the JOIN machinery.
- Fit replaces every segment with a classic equal-parameter BIARC: two
arcs per segment meeting tangentially at an inserted knee, both
segments at a vertex sharing that vertex's tangent — the whole run is
tangent-continuous (verified: zero tangent jump on L/closed/zigzag/S
shapes). Spline resamples the vertex frame as a uniform cubic
B-spline (8 samples per span); Decurve straightens every bulge.
- Earlier hardening kept: undo snapshot before the mutation, immediate
repaint, polyline-only pick validation.
- Vertex editing lives on grips, so no Edit-vertex submode; instead the
vertex grip hover menu gains Break — a closed polyline opens at the
vertex, an open one splits into two (interior vertices only),
handled driver-side as an entity replacement.
JOIN itself: segs_of now emits one segment per span of an OPEN
polyline (bulges kept), so polylines merge with their neighbours —
PEDIT Join's set always contains the target polyline and used to abort
every time; plain JOIN had the same gap. JOIN also honours pickfirst:
launched with two or more objects selected it joins them immediately.

REFCLOSE only wrote the temp copies made at REFEDIT entry back into
the block, so anything drawn (or pasted / offset) during the session
stayed behind in model space (#423). The session now captures a
handle watermark at entry; on close, every current-space entity
allocated at or above it joins the working set — Save folds it into
the block through the same inverse transform, Discard removes it.
Covers every creation path with no per-command hooks.

Entering the block editor reframes the camera on the block's own
geometry, but nothing remembered where the model view was — Save /
Discard returned to the layout with the camera still parked at the
editor's framing (#425). The session now captures the camera on entry
and both exits restore it exactly.
