bherbruckandClaude Opus 5.5 2db9e66048 STEP orientation check: judge only revolution faces, no drifting parameter hint 
Free-form strips (a curved-edge fillet's B-spline bands round a saddle) vary
their normal too much along the loop for the loop-direction test, and the
hinted nearest-parameter search drifted on them: false 'runs clockwise'
reports on faces that round-trip exactly. The check now covers cylinders,
cones, spheres and tori (closed surfaces, where a loop read the wrong way
silently gives the rest of the surface); volume checks cover the rest. It
still flags all 8 sphere corners of a fillet box with their sense flipped.

bherbruckandClaude Opus 5.5 66fa6fe584 Dialogs for joints, sheet metal and plastic 
ASSEMBLE panel (SOLID, SHEET METAL, PLASTIC): New Component, Joint, As-built Joint, Joint Origin,
Rigid Group, Drive Joints, Motion Link, Interference. Joint origins are picked by hovering:
faces snap to their centre (round faces to the centre of the nearer end), edges to their middle
(round edges to their centre), vertices to themselves, shown as glyphs with their z axis. The
Joint dialog has the motion type, angle, offsets X/Y/Z, flip, per-value limits and Animate (the
preview plays the motion); joints and drives preview on the placed model (world states).
Drive Joints moves live with a slider. Interference lists the overlaps and shows them red.
Joints appear in the timeline and in a Browser Joints folder (edit, drive, suppress, delete).

SHEET METAL tab in Fusion's layout: Flange (base, edge or contour, from the picks; height arrow
on the canvas), Hem, Unfold, Refold, Convert to Sheet Metal, Sheet Metal Rules (rule manager),
Create Flat Pattern (flat view with up/down bend lines, bend table, DXF export).

PLASTIC tab with SETUP: Boss, Lip/Groove, Snap Fit, Rest, Manage and Assign Plastic Rules; Rib,
Web and the shared solid commands on the tab.

Every feature dialog has live preview, Edit Feature and pre-selection; icons drawn in code.
Toolbar layout per tab in workspace.rs; tests for the dialog to command mapping.

bherbruckandClaude Opus 5.5 7f9a8f2afd Two-entity constraints move only the second pick (tangent, parallel, perpendicular, equal, concentric, coincident, collinear, symmetric, midpoint): the constraint is applied with the first entity held (solve_holding), the second keeping its size where it can (lines turn and slide, circles translate), then resizing; if the second is fixed, projected or fully constrained the first moves instead, and if neither can the constraint is refused and nothing changes; later solves hold nothing. Context-menu constraints keep the selection order; a curve picked before a point puts the point on the curve

bherbruckandClaude Opus 5.5 7382ebd6e8 STEP export: Fusion round-trip fixes (sense, analytic surfaces, horn torus) 
- Surfaces of revolution follow ISO 10303-42 strictly in reader and writer: the
  normal is d/d(angle) x d/d(profile), the opposite of truck's revolution, as
  Fusion reads it (fixes Fusion inverting fillet sphere corners and the dimple).
  step_orientation_errors flags faces whose loop runs clockwise round their
  normal; engine, oracle and kernel round trips assert it.
- Revolved faces with analytic profiles are written as native PLANE,
  CYLINDRICAL/CONICAL/SPHERICAL/TOROIDAL surfaces, and the pieces truck splits
  a revolution into are merged back into one face per surface (with a seam
  edge for full turns), so face counts match other systems.
- A horn torus (tight sweep: tube touching its axis) is written as one rational
  B-spline face whose loop passes the pole twice, with truck's zero-length pole
  edges collapsed, instead of a degenerate surface of revolution; the reader
  starts such figure-eight loops off the pole (Fusion's own part 50 now imports
  with the right volume).

bherbruckandClaude Opus 5.5 a6dc759a02 Fix: rectangles over-constrained after an edit (dragged sides collapsed) 
Parallel and perpendicular residuals were the cross/dot product over the sum of
the line lengths, so the solver could satisfy them by shrinking a line to
nothing. Dragging a corner of a rotated (3-point) rectangle collapsed a side to
zero; every later dimension then conflicted. The residuals are now the sine or
cosine of the angle (over the product of the lengths), which shrinking can't
improve. Tests drag, dimension, pin and square center, 2-point and 3-point
rectangles and check their degrees of freedom; oracle unchanged at 53/66.

bherbruckandClaude Opus 5.5 8c88fb8d2d Measure: split triangles that cut through curved faces onto the surface (trimmed faces after booleans were measured up to 15% off; 61's keyway volume now matches); oracle step check shows the original volume 
Oracle: 53/66.

bherbruckandClaude Opus 5.5 063d55bdb3 Sketch drawing: a point snapped to a line's midpoint stays there ("mid:<line>" point arguments add a MidPoint constraint)

bherbruckandClaude Opus 5.5 0da4c756c8 Sketch drawing inference: the cursor snaps to line midpoints and to horizontal/vertical alignment with the previous point (with an H/V/Mid hint), so lines drawn that way get their constraints inferred
