XS_​POLYBEAM_​CURVATURE_​TOLERANCE

Category in Advanced options dialog box: Modeling properties

Use this advanced option to define the tolerance used in detecting the curvature between three points in a polybeam. The default is 2.0e-6.

This advanced option defines the difference in dot products between two unit vectors formed by two consecutive polybeam arc chamfer handles. If the dot product differs less than this value, the curve is considered to be a straight line, and the arc chamfer is omitted.

Generally, you need to change the default value only if you are working with long, thin or very complex polybeams. Change the default value in the following situations:

  • If the polybeam is only very slightly curved and it looks like a straight polybeam in the model, you need to give a smaller value, such as 2.0e-10. A larger value makes polybeams with only a slight curvature straight.

  • If the value is unnecessarily small (smaller than default value for simple polybeams), there might be performance issues.

  • If the tolerance is set to a value that is too small (< e-11), the polybeam may break.
