Surface Rendering Options

CAD surfaces, sometimes referred to as B-Reps or NURBS—Non-Uniform Rational B-Splines, are mathematically defined and have an “exact” representation. However, curved surfaces must be converted into a series of approximated flat faces to render in the graphical view. The quality of this approximation is determined by the Surface Rendering Options set here.

If you find that your curves and surfaces are not being represented accurately enough for your liking, or if you see “tearing” in your CAD surfaces, you can modify the surface rendering options.

Note that this setting also applies to spline curves:

When laying out points on an object’s vertices, this setting affects how many points are constructed.

Draw Silhouettes in Hidden Line Removed Mode. By default silhouette's are not drawn in hidden Line Removed mode. This option allows them to be drawn.
