Recipe: create a primitive working mesh

Use when

You need a box, sphere, cylinder, capsule, cone, disc, or torus as the starting point for later processing.

Steps

1. create a working mesh
2. call a primitive append function on the working mesh
3. if needed, continue into meshops / deform / UV steps
4. only write back if asset output is required

Output

• default output: working mesh path
• asset output only if explicitly requested

Recipe: create profile-based geometry

Use when

You need extrude / revolve / sweep style generation.

Steps

1. create a working mesh
2. construct the required polygon/path inputs
3. call the relevant GeometryScript modeling/path functions
4. validate geometry
5. hand off the working mesh or write back

Recipe: create asset output from generated geometry

Use when

The end result must exist as a real mesh asset.

Steps

1. create and populate a working mesh
2. optionally preprocess normals / UV / repair
3. write back to an existing asset or create a new asset
4. if required, generate collision as a separate finalization step

Common mistakes to avoid

• writing to assets too early before geometry preparation is complete
• skipping the working mesh stage
• combining creation and business-layer policy decisions in the same step
