Mesh Clean-up

These tools are to help cleanup degenerate geometry and fill in missing areas of a mesh.

Fill Holes

Mode: Edit mode

Menu: Mesh » Clean up » Fill Holes

This tool is can take a large selection and detect the holes in the mesh, filling them in.

This is different from the face creation operator in three important respects.

holes are detected, so there is no need to manually find and select the edges around the holes.
holes can have a limit for the number of sides (so only quads or tris are filled in for example).
mesh data is copied from surrounding geometry (UV's, vertex-colors, multi-res, all layers), since manually creating this data is very time consuming.

Mode: Edit mode

Menu: Mesh » Clean up » Split Non-Planar Faces

This tool avoids ambiguous areas of geometry by splitting non-flat faces when they are bent beyond a given limit.

Mode: Edit mode

Menu: Mesh » Clean up » Delete Loose

This tool removes disconnected vertices and edges (optionally faces - off by default).

Mode: Edit mode

Menu: Mesh » Clean up » Degenerate Dissolve

This tool collapses / removes geometry which you typically wont want.
