0.1mm was generating thousands of unnecessary points on straight
edges. Now: 1mm default, 0.5mm minimum, 500 max per edge.
Curves still get proper sampling, straight edges stay lean.
NXOpen Python wraps UF methods with version-specific names.
Now dumps available methods on UF.Modl, UF.Eval, UF.Curve
and tries them in order. Detailed logging shows which method
was found and used, plus raw result format on parse failures.
UF_EVAL.Evaluate() doesn't exist in NXOpen Python.
UF_MODL.AskCurveProps(tag, param) uses normalized 0-1
parameter and returns (point, tangent, normal, binormal,
torsion, radius). Works on all edge types.
- Uses ISOGRID_RIB_sandbox_N_thk expression for thickness
- Creates expression if missing, uses existing if present
- Symmetric extrude: ±thk/2 from sketch plane
- Fallback to literal value if expression fails
- Create section explicitly if builder.Section returns None
- Try 3 approaches for adding curves: CreateRuleCurveFeature,
CreateRuleCurveDumb with options, CreateRuleCurveDumb without
- Detailed step-by-step logging for debugging
- Get help point from first sketch curve for section seeding
Full cycle now automated:
1. Delete old extrude (if exists)
2. Delete old sketch (try ReplaceFeatureBuilder first, fallback to delete)
3. Create new sketch with rib geometry
4. Extrude new sketch by rib thickness along face normal
5. Name both features for identification on next iteration
Rib thickness read from profile JSON (parameters_used.thickness)
with fallback to geometry JSON or default 10mm.
No more manual extrude step needed between iterations.
Replaces naive ReplaceEntity approach with NX's proper
ReplaceFeatureBuilder API. This mirrors the interactive
right-click → Replace Feature workflow:
- SelectFeature: old sketch to replace
- ReplacementFeature: new sketch taking over
- DoAutomaticGeomMatch: auto-maps curves
- DeleteOriginalFeature: removes old after remap
- Fallback: manual delete if builder fails
All downstream features (extrude, trim) automatically
re-reference the new sketch.
Model curves (part.Curves.CreateLine) are SmartObjects that can't be added
to a sketch via AddGeometry. Switch to SketchLineBuilder which creates
native sketch geometry directly (SetStartPoint/SetEndPoint/Commit).
