Untriangulate
If you have an object built only of triangles (e.g. imported from another program), CINEMA 4D can
try to convert the triangles into quadrangles. This works only as long as the triangles that you want to
convert will result in a planar quadrangle. Triangles that cannot be converted are left in their original
state. So, Untriangulate works only for triangles that result in planar quadrangles. If Evaluate Angle is
disabled, CINEMA 4D tries to convert all triangles to quadrangles. This can result in unwanted edges
and shading errors. In such cases, enable Evaluate Angle.
Untriangulate does not affect n-gons.
Retriangulate N-gons
Look up ‘N-gon Triangulation mode’ in the index.
Remove N-gons
This command converts the selected objects’ n-gons to triangles and quadrangles. While you are
modeling you can check up how the n-gons would be triangulated by enabling the N-gon Lines
option in the viewport settings on the Filter tab (viewport: Edit > Congure). Keep in mind that these
triangulation lines may change at any time while you are editing the mesh.
