This Skill eliminates the common first-try failures and generic "valid but wrong" outputs when authoring brepjs .brep.ts CAD models, ensuring your parts are not just kernel-valid but match the exact design brief on the first verify run, no wasted iterations on type errors or mismatched dimensions.
Use the implement skill to author a brepjs .brep.ts part for a flanged coupling, following the hard rules for imports and unwrapping to pass verify on the first try.
High-intent search queries and answers about installing and using this skill.
To write brepjs CAD parts that pass verification on the first try, enforce mandatory named imports, explicit Result unwrapping, shape-first transform syntax, and accurate bounds and volume assertions to eliminate kernel errors.
Parametric solid models output valid but wrong dimensions when expected block assertions lack accurate bounds and volume checks. Writing explicit assertions catches multi-body assembly sizing mismatches during verification instead of producing valid-but-wrong geometry.
Model involute gears and threaded rods using parametric CAD APIs by applying verified reference recipes. These specialized workflows enforce correct solid modeling practices, ensuring complex mechanical parts like impellers and threads generate without reverse-engineering geometry.
Yes, you can use boolean assemblies and modifiers like fillet and shell for mechanical design in brepjs. The API requires ValidSolid requirements for modifiers and explicit Result unwrapping to execute these operations reliably without kernel errors.
The hard rules for importing and unwrapping functions in a .brep.ts file require using mandatory named imports for all API functions and explicit Result unwrapping. Following these syntax rules eliminates 90% of first-attempt type errors in parametric CAD models.
Yes, brepjs supports STEP export for solid models and assemblies. The parametric design workflow includes creating 2D sketch extrudes and revolves, applying boolean operations, and exporting the final verified geometry to STEP format for mechanical design use.
