The Cap command fills planar holes in objects with planar faces.

It is caplable of capping surfaces, Meshes and SubDs.

Command-line options (Mesh/SubD only)

-DeleteInput: Specify if the input object will be deleted.

-Crease

• Yes: Do not weld the vertices along the cap boundary.

• No: Welds the vertices along the cap boundary.

• Triangles

  • Yes: Fills a planar opening in a SubD or mesh with triangle faces.

• No: Fills a planar opening in a SubD with a single face, or in a mesh with an n-gon.

Aditional Notes

Caps will always be made up of triangles when:

• A SubD or mesh cap has a hole (an inner boundary).

• Any part of the outer boundary of a SubD cap is not convex.

You can use the MergeFaces command to combine the triangles into a single face as needed.
