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.
