Clean Up

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

Decimate Geometry

Reference

Mode

Edit Mode

Menu

Mesh ‣ Clean up ‣ Decimate Geometry

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.

Fill Holes

Menu

Mesh ‣ Clean up ‣ Fill Holes

This tool 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:

  1. Holes are detected, so there is no need to manually find and select the edges around the holes.

  2. Holes can have a limit for the number of sides (so only quads or tris are filled in for example).

  3. Mesh data is copied from surrounding geometry (UVs, vertex colors, multi-res, all layers), since manually creating this data is very time-consuming.

Make Planar Faces

Reference

Mode

Edit Mode

Menu

Mesh ‣ Clean up ‣ Make Planar Faces

The Make Planar Faces iteratively flattens faces. This can happen with faces over three vertices and it is a common convention that faces should be kept planar.

Factor

Distance to move the vertices each iteration.

Iterations

Number of times to repeat the operation.

Split Non-Planar Faces

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.

Split Concave Faces

Reference

Mode

Edit Mode

Menu

Mesh ‣ Clean up ‣ Split Concave Faces

This tool can be used to convert any Concave Face to convex by splitting the concave into two or more convex faces.

Delete Loose

Reference

Mode

Edit Mode

Menu

Mesh ‣ Clean up ‣ Delete Loose

This tool removes disconnected vertices and edges (optionally faces).

Degenerate Dissolve

Reference

Mode

Edit Mode

Menu

Mesh ‣ Clean up ‣ Degenerate Dissolve

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.

Merge by Distance

Reference

Mode

Edit Mode

Menu

Vertex ‣ Merge by Distance, Context Menu ‣ Merge by Distance

Merge by Distance is a useful tool to simplify a mesh by merging the selected vertices that are closer than a specified distance to each other. An alternative way to simplify a mesh is to use the Decimate Modifier.

Merge Distance

Sets the distance threshold for merging vertices.

Unselected

Allows vertices in the selection to be merged with unselected vertices. When disabled, selected vertices will only be merged with other selected ones.
