To remove degenerate faces

Degenerate faces are triangles that have two of their three corner points at almost, or even exactly, the same location.

Degenerate faces are often created during other operations that involve retriangulation. In many cases, degenerate faces do not result in poor production parts, but they can dramatically increase the number of corner points and hatches in the slice files. As a result, calculation and production can take much longer than actually necessary. They may even throw off some algorithms completely when two or even three corner points are exactly at the same location: Effectively, they form a one-dimensional line, or even a point, which makes the direction in which a regular triangle's normal would be facing not defined.

This command is only available in the context view, by using the script action, or through the context menu. The default, non-script threshold for deciding whether an edge is short enough to make a triangle a degenerate one is adjustable in the Settings.

1. In the context view, switch to the Actions tab.
2. Click Remove Degenerate Faces.
3. Click OK.

The triangle shaded in orange has two of the three corner points at practically identical positions, so it appears only as a line.
