Approximation Method

Tolerance & Surface Offset options.

By Tolerance

The approximation of the surface will be determined by the surface tolerance - the maximum allowable deviation between the surface and the triangular planes used for surface approximation.

Example: a long, nearly-horizontal surface:

By Tol. + Length

The approximation of the surface will be determined by the more stringent condition - surface tolerance or the length of the triangles used for approximation.

Max. Triangle Length

If By Tol. + Length is chosen, enter the maximum length of the approximation triangles.
