A drawing whose bodies are built only of planes opened without error but
drew nothing, while the solids still selected. Pre-7.0 SAT writes strings
as a length and the characters, so one may contain the record
terminator; ODA's builder emits `8 STEP Id#` inside a dxid-attrib. The
parser split there, every later record answered to the wrong index, and
faces resolved their surface pointer to a coedge or a vertex, so nothing
meshed.
Fixed upstream in acadrust 41149d7. All 22 solids in the reported drawing
now parse to exactly the record count their header declares, and all 22
mesh.

A revolution comes back from rsweep as three 120-degree segment faces,
but every hole was attached to the first of them. A window wider than a
segment cannot sit on one face, so that face turned invalid and its
whole third of the tube vanished -- the pump's cylinders lost 120
degrees of wall each and the solid read as open where they met the body.
One of them shed a segment with no hole involved at all, so chasing the
individual causes would not have covered it.
Measure the result instead: after a cone face whose boundary closes the
revolution is triangulated, check that the meshed vertices actually span
it, and hand the face to the parametric sampler when they do not. That
catches a tear whatever produced it, while genuinely partial cones and
every non-cone surface pass straight through -- the tee's pierced run
cylinder still meshes through the kernel.
Also bring truck's chord tolerance in line with the detailed LOD. Truck
emits a single mesh rather than an LOD ladder, so a tenth of the radius
left a wide pipe as a hexagonal prism whose flats sank nine units inside
the true surface, pulling the wall away from the caps and planar faces
that meet it.

The cone-surface record's trailing real is a parameter scale, not
geometry. It equals the radius on many bodies, so cylinders generally
came out right, but where the two diverge the lateral surface was built
at the wrong size while the flat caps stayed on their own rims -- a
gauge dial drew as a ring around its own face, its band at 43.2 against
caps at 34.56.
The major axis is the radius vector at the reference cross-section, so
its length is the radius. Route every read through one helper and keep
the record's field only as a fallback for a degenerate major axis, so
the band, the silhouette generators, the isolines and the coaxial-rim
check all size themselves the same way. Taper is unchanged: the major
axis is still the h=0 radius that radius + h*tan(a) extends.

Sphere faces drew as complete balls. ACIS parametrises a sphere about
any pole, so a vessel's dished head is commonly bounded by a circle that
is no line of latitude in that frame, and a theta/phi bounding box of
such a boundary covers nearly the whole ball. Derive the window
analytically instead: when a face's loops are circles lying on the
sphere, re-pole the frame onto their common axis, where each seam is an
exact latitude at acos(d / R). One ring bounds a cap, two bound a zone;
the material side comes from the boundary winding, reusing the helper
the torus path already had.
Separately, the longitude wrap flag was resetting the colatitude window
to the whole meridian. A cap centred on the pole covers every longitude
while still ending at its seam, so that reset grew every cap back into a
ball. Trim the two angles independently and rename the flag theta_full
so the split reads at each use, including the silhouette generator,
which skipped the colatitude test the same way.
Cone faces took their height span from the first boundary loop alone. A
lateral face closed off by one rim and one pierce curve -- a pipe branch
meeting its run -- carries its two ends on different loops, so the tube
was sized to whichever came first and the leg above the junction went
undrawn. Read every loop.

Add a searchable block palette with previews, file import, collision-safe nested definitions, and dependency/table-record import. Keep palette thumbnails current across drawing switches and block-definition edits.
Route model, paper, viewport and nested block content through one traversal while preserving leaf renderers. Carry decoded material state into mesh shading and harden solid geometry conversion.
- preserve command history colors after reopening
- remove collapsed command bar residue and split the unsaved prompt
- read system text when the drawing clipboard is empty

- Keep the floating panel near the selection and inside the viewport
- Persist the toggle and hide the panel without a selection
- Show only Material in 3D Visualization
Keep OFFSET picks current across newly created entities and preserve the command after pick-first offsets.
Use palette-provided contrast colors for active status controls and Alias Editor removal buttons.

Scope revolution spans to face boundaries and preserve pierced cylinders and rational spline lofts so valid bodies no longer produce stretched or missing shells.
