1.7.9. Clean up¶
These tools are to help cleanup degenerate geometry and fill in missing areas of a mesh.
1.7.9.1. Decimate Geometry¶
Reference
The Decimate Geometry tool allows you to reduce the vertex/face count of a mesh with minimal shape changes.
- Ratio
- Ratio of triangles to reduce to. 
- Vertex Group
- Use the active vertex group as an influence. - Weight
- Strength of the vertex group. 
- Invert
- Inverts the vertex group. 
 
- Symmetry
- Maintain symmetry on either the X, Y, or Z axis.

This tool works similar to the Decimate Modifier.
1.7.9.2. Fill Holes¶
Reference
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 (UVs, vertex-colors, multi-res, all layers), since manually creating this data is very time consuming. 
1.7.9.3. Make Planar Faces¶
Reference
1.7.9.4. Split Non-Planar Faces¶
Reference
This tool avoids ambiguous areas of geometry by splitting non-flat faces when they are bent beyond a given limit.
1.7.9.6. Delete Loose Geometry¶
Reference
This tool removes disconnected vertices and edges (optionally faces).
1.7.9.7. Degenerate Dissolve¶
Reference
This tool collapses / removes geometry which you typically will not want.
- Edges with no length. 
- Faces with no areas (faces on a point or thin faces). 
- Face corners with no area.
