πŸ“– About This Skill

name: onshape-featurescript description">Generate Onshape FeatureScript code for custom CAD features and parametric parts. Specializes in dust collection fittings library (wyes, elbows, adapters, crosses). Use when user asks to: (1) create FS features (gears, fittings, brushes), (2) modify existing FS, (3) debug FS errors, (4) build libraries with consistent patterns (enums, shells, labels). Patterns for Z-axis fittings, wrapped labels, safe unions/shells. Triggers: 'Onshape FS for X', 'FeatureScript wye/elbow', 'dust fitting'.

Onshape FeatureScript Generator

Quick Start

Analyze request β†’ Match pattern β†’ Gen FS code β†’ Validate logic.

Core Workflow: 1. Precondition: Enums/lengths/reals w/ bounds. 2. Body: Sketches β†’ Extrudes β†’ Booleans β†’ Shell β†’ Wrap/Thicken labels. 3. Pitfalls: qOwnedByBody(finalBody), if/else (no ternary lengths), cylinder(coordSystem).

Key Patterns (Memorize)

  • Enum + Cond Param:
    •   export enum AlignmentStyle { Centered, Tangent, Offset };
  if (definition.alignment == AlignmentStyle.Offset) { isLength(def.offsetDistance...); }
  • Safe Shell Caps:
    •   var capFaces = qFacesParallelToDirection(qOwnedByBody(finalBody, EntityType.FACE), vector(0,1,0));
  • Union Primary First:
    •   qUnion([qCreatedBy(id+"inlet", EntityType.BODY), ...]);
  • Wrapped Label: skText β†’ opWrap β†’ opThicken.

    • Dust Fittings Lib

    Z-axis: Inlet Z=0 (-Z), Outlet Z=trans (+Z), Branch +X. See FITTINGS.md for full spec/pitfalls.

    Resources

  • API Patterns: PATTERNS.md
  • Fonts: AllertaStencil-Regular.ttf for labels.
  • Validate: Test mentally; no runtime here.

    • Gen code β†’ User pastes to Onshape FS editor.
