• A traced intersection's short last span is merged untested, so an End's rib fails check (Bad Gap 4.1e-5 > 4e-5)

• SmFilletCorner::MakeAnalyticCornerSurface returns a failing status as TRUE, so the corner skips its Coons patch

• Exact circular sections of one round mix one-arc and two-arc circles, so the skin leaves the balls (1.97e-3 off a variable round)

• A convex round larger than the wall it rounds builds a body that intersects itself (BandCutsThePart counts the crossing as material kept)

• Inside-out and negative-angle unbounded SmCone are parameterised unlike their NURB (CreateIsoCircleFromPoint builds the circle far from the point, or none)

• Drafted extrusion: an arc's wall is a ruled B-spline, not its exact cone, so coincident cone faces don't merge

• Interior creases: faces that pass today are not G1 inside (G2 round nets 4.3e-3 rad, variable spline round, offset fits)

• SmPlane::DropCurve clamps a rational rail's control points to the plane's uv domain, so trim curves along conic rails are fitted, not exact
