AICAD Model 3D

Model slowly and transactionally: reason about one feature, validate it, execute it, read it back, then continue.

Workflow

1. Call aicad_capabilities and aicad_solidworks_doctor.
2. Decompose the part into an ordered feature graph. Start the base sketch at [0,0,0].
3. For every feature, state:
   • purpose;
   • relation to earlier features;
   • dependency and support feature;
   • profile dimensions and location;
   • operation depth/end condition;
   • expected volume delta and resulting bounds.
4. Call aicad_get_3d_plan_schema, then author a schema 1.0 plan. Read plan-schema.md when creating or editing the plan.
5. Call aicad_validate_3d_plan. Correct the first reported invariant violation before execution.
6. Call aicad_build_solidworks_part with execute=true.
7. Accept a feature only when its report passes all gates: fully constrained sketch, feature error code zero, fault-free single body, expected volume/delta/bounds, and persistent support reference resolution.
8. Deliver the SLDPRT, STEP, audit, manifest, and SolidWorks report together. Summarize the feature-to-feature reasoning.

Hard rules

• Never issue raw mouse/keyboard CAD drawing as the primary modeling path.
• Never create all features first and inspect only the final shape.
• Never continue after a failed feature transaction.
• Never reference volatile names such as Face1 or Edge3 in a plan.
• Prefer principal planes and semantic support geometry. Require persistent-reference re-resolution after rebuild when topology is used.
• Treat a non-null feature object as insufficient evidence of success.
• Keep identifiers and the SolidWorks execution channel ASCII-safe; keep human explanations in UTF-8 plan/audit fields.
• Do not save a partial SLDPRT when any gate fails.

Read failure-recovery.md when execution fails.
