Legacy sketch mapping

Read-only references, never executed:

  • ../../exploded-preview-preparation/runtime-dev9-build-r1/source/addin/AdomBridge/commands/mechanical/sketches.py, SHA256 1117e1e18d12ce3b4a92a20da43e4283d717f041ec4b05afdc64b5bb0984fe0c.
  • Adjacent schema.json, SHA256 6f704e05de031fa8ef329dc7be0b02d3a2b167eeb2fbc44ec6c2d933af4f7b48; sketch_geometry schema has eight variants, 1–128 items, 3–128 polygon sides, 2–128 spline points, mm coordinates and degree angles.
  • Adjacent core.py::number accepts finite non-Boolean numeric values and optional positivity. test_mechanical_transactions.py in the published-readback tests includes Boolean-radius schema refusal. No legacy Python test was run.
Legacy behavior Rust pure preparation Remaining difference/gate
point Two/three-number PointMm; mm/10, zero Z only for 2D New numeric range/underflow checks; no Point3D SDK allocation.
Point/line/circle branches Typed point/line/center-radius instructions Native creation, validity and readback absent; extra degeneracy/envelope checks.
Rectangle branch Four ordered corners/lines, original PrimitiveKind::Rectangle retained Native addTwoPointRectangle ordering and helper constraints are not qualified by these coordinates. Explicit equal-Z guard.
Arc branch Signed radians plus analytic Z-rotation endpoint Native plane/projection semantics and measured endpoint absent; equal Z, finite envelope and noncollapsed chord required.
Polygon branch Same circumradius, positive angular order and closed line chain Angle bounded/reduced before trig; floating-point bits need not match Python; minimum edge length is stricter.
Slot branch Left-perpendicular half-width, line/negative-half-turn/line/negative-half-turn order Same Z tolerance and center distance threshold; stricter radius/envelope/representability rules; exact shared predicted endpoints.
Fitted spline branch Preserve all ordered fit points and closed flag No solved spline is produced; stricter closed minimum and repeated-endpoint refusal.
Construction assignment Curve Option<bool> preserved per generated entity No property setter; invalid point flag rejected at typed JSON boundary.
Complete geometry batch All validation/expansion/output checks before returning a plan Pure preparation is not legacy transaction grouping or rollback.
quantity Numeric lengths used by these primitives only Unit-bearing expressions, dimensional validation and evaluated ValueInput require Fusion UnitsManager; not approximated here.
sketch_create, component, plane, axis, get_sketch, named No native equivalent Exact SDK identity/ownership/validity and current revision checks are integration work.
Constraint/dimension/project/edit/plane handlers Not implemented Depend on selected native entities, current geometry, solver or units; this crate does not supply their SDK effects or claim complete sketch porting.

The prepared JSON deliberately has no session, document, revision, guarded native selector, transaction or durable-effect fields. It is not a compatible replacement for a legacy request or result. Native integration and public exposure are later gates.
