Converting polygon faces to triangles is a quick way to ensure non-planar faces render properly. Converting polygon faces to quads is a good way to clean up polygons or reduce the number of faces.
To convert faces to triangles or quadrangles
- Select the faces.
- Do one of the following:
- Select
Mesh > Triangulate.
- Select
Mesh > Quadrangulate.
Note: Attempting to quadrangulate n-gons may not result in anything happening. To do this, you will often need to triangulate the faces first, before quadrangulating the result.
