solid_boolean() collects the selected solids straight out of
scene.selected, a HashSet, and then uses handles[0] and handles[1] as the
two operands. Set iteration order is arbitrary and can differ between
runs, so SUBTRACT — the one non-commutative operation of the three — could
cut either solid out of the other for the same selection.
Sort the pair by handle, so the solid created first is the body the other
is taken out of. UNION and INTERSECT are unaffected.
The last four truck crates are gone from the manifest. What they were doing
falls into three parts, and each now has one answer instead of two.
NURBS evaluation. truck was carrying B-spline curves and surfaces for the
SPLINE entity, hatch boundaries, BLEND's endpoint frames, the spline preview
and ACIS spline-surface faces. The kernel now has both, over one de Boor
written across however many coordinates a control point holds — so a plane
curve and a space curve cannot drift apart, and a surface is the same
algorithm applied twice. The rational and the polynomial cases stop being
separate types: weights absent means polynomial.
The entity conversion. Every LINE, ARC, ELLIPSE, SPLINE and polyline was
built into truck topology purely so it could be sampled back into points.
They are sampled through `entities::curve` now, which is where each one's
geometry is already defined once and what EXTRUDE and REVOLVE read — so a
circle drawn on screen and a circle handed to the Model tab come from the
same definition. That retires four of TruckObject's variants and the module
is renamed for what it does.
SWEEP and LOFT. Both only ever produced a mesh, so both are built from point
lists: a band of quads per span, and a lid where a profile closes. Lofting
profiles of different densities resamples them by distance rather than by
index, so a circle lofted to a square no longer twists.
Two things worth noting for anyone reading the old comments. The tolerance
globals that lived in the tessellation module were never about truck at all —
they are the per-frame chord height, and they move to `curve_tol`. And the
rule that a profile handed over as `Lines` silently broke EXTRUDE and REVOLVE
no longer holds: those read the curve directly and never look at this channel.
The two `automation` test failures are unchanged from before this and are not
caused by it.

Every 3-D solid OCS makes or opens now goes through cadkernel, which holds
analytic surfaces — a cylinder is a cylinder record, not a spline that looks
like one. That is what lets a solid built here be written back out as exact
ACIS instead of a triangulation, and a facetted export is a one-way door: the
next application to open the file would have no way back to the circle.
The Model tab's seven primitives, the Design-group booleans, 3DROTATE,
3DMIRROR, 3DALIGN, SLICE, SECTION, POLYSOLID and PYRAMID all come from the
kernel now, and `scene.solid_models` holds a `Body`. A mirrored solid needed
its own care before; the kernel reverses the loops on the way through, so it
comes back the right way out rather than lighting black.
EXTRUDE and REVOLVE sweep the profile `entities::curve` already defines, so a
circle, an arc-bulged polyline and a closed spline arrive as the same thing.
A circle extrudes into four cylinder patches rather than a run of chords, and
a profile turned about an axis becomes a cone, a sphere or a torus. A spline
profile has no analytic side wall and is refused rather than approximated.
ACIS goes both ways through the codec's own bridge: `lift` to read and
`append` to write. That drops the 679-line truck conversion and the planar-
only exporter, and the tessellator keeps its bespoke sampler as a fallback for
whatever the kernel cannot yet express — reported rather than passed off as
whole, since a mesh missing a wall looks finished.
truck-shapeops is no longer used and is gone from the manifest. truck-modeling
stays for now: fourteen files use it as a 3-D NURBS evaluator, which the
kernel has no answer for yet, and SWEEP and LOFT have no kernel operation
behind them either.
The two `automation` test failures are unchanged from before this and are not
caused by it.

The v0.7.0 web (GitHub Pages) release failed to compile under
--no-default-features. Two symbols leaked into the wasm build:
* `solid_section` (SECTION command) used truck-meshalgo directly
(`triangulation`/`extract_interference`), but that crate is gated
behind the `solid3d` feature which is off on wasm. Gate the function
with `#[cfg(feature = "solid3d")]` and add a stub for builds without
it, mirroring `solid_model::boolean`.
* `register_as_handler` was `#[cfg(not(wasm32))]` while its caller
`set_default_app_blocking` was not, so wasm couldn't resolve it. Drop
the wasm gate; the existing non-win/lin/mac arm already returns `Ok`
on wasm, matching `unregister_handler`.

- FLATSHOT: project the selected solid's edges to 2D Line entities at Z=0
- CONVTOSURFACE: convert the selected solid(s) to Surface entities
Both reuse the cached B-rep's edge wires. COMMANDS.md: 219/262.

Integrate a large batch of standard CAD commands and fix several
name/behaviour mismatches, with no product references in code.
3D solids (reusing the truck B-rep pipeline):
- SLICE, INTERFERE, PRESSPULL, POLYSOLID, PYRAMID, SECTION
- 3DROTATE, 3DMIRROR, 3DALIGN (cached-solid transforms)
Annotation / text:
- ARCTEXT, SPLINEFIT (Catmull-Rom to Bezier), DIMJOGGED, OBJECTSCALE
(XData markers honoured by the existing geometry-gen / tessellator)
Blocks / misc:
- NCOPY (block-content extraction via explode_entity)
- OPTIONS, SYNCPVIEWPORTS, THICKEN, plus earlier toggles, aliases,
system variables, and layer/style/view commands
POINTCLOUD/RECAP and UNDERLAYLAYERS/UOSNAP are intentionally left out:
they require a proprietary binary / PDF-layer parser, a GPU point
renderer, and real test files.

Match the `*_model` naming of the sibling render models (wire_model,
hatch_model, mesh_model, image_model). Also realign the related Scene
API for consistency: model_solids → solid_models, add_model_solid →
add_solid_model, register_model_solid → register_solid_model.
No behavior change; build and tests are green.

Move the 30 flat modules under src/scene/ into six folders by role:
convert (entity→geometry), text (fonts/shaping), model (render models),
pick (hit-test/selection/grips/xclip), view (camera/transform/render),
cache (block + property caches). pipeline/ is unchanged.
Full path migration — all `scene::X` references become
`scene::<group>::X`, no compatibility re-exports. render.rs items that
were `pub(super)` (parent was scene) become `pub(in crate::scene)` to
keep their original scene-wide visibility.
No behavior change; build and tests are green.

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.
