Filter triangles
Menu: Adjust mesh Icon: No short cut
Filters degenerated triangles from the triangle mesh
This function searches for degenerated triangles and removes them from the triangle mesh. In
order to keep interference with the triangle mesh low, only triangles within a defined tolerance
are taken into account. You can define via the filter criteria, which of the triangles are
considered as degenerated.
Dialog Filter triangles
Filter criteria
The following options determine when a triangle is considered as degenerated.
Inwards angle less than: If one of the inwards angles of the triangle is lesser than the defined
angle in degrees.
Surface area less than: If the surface area of a triangle is smaller than the defined value in mm 2 .
Edge length less than: If the length of a triangle edge is lesser than the defined value in mm.
Tolerances
The tolerances determine how much the triangle mesh may be changed.
Maximum angle deviation: Defines the maximum angle in-between the triangle that is to be
removed and its neighbors. The triangle is only deleted if this angle is lesser than the defined
maximum value.
Number of calculation passes: The changes in the geometry of the triangle mesh that occur
during one filter pass may produce additional triangles that lie within the defined tolerance. In
order to filter these new triangles as well, several calculation passes are required.
