How to Separate and automatically add missing faces? I'm attempting to separate out pieces of my model and would like to automate adding faces to the "previously attached" holes. How can I do this?

Alternative: Is there a better way that "separate"?
it's not really automated but you could use the "fill holes" clean-up tool.


separate the meshes
in edit mode, select all vertices
Mesh ‣ Clean up ‣ Fill Holes
repeat steps 2 and 3 for all separated meshes
