A part section between two steep sections can be either shallow or steep. SURFCAM uses the section length to calculate if it is steep or shallow for machining purposes. If the section is shallow and the section length is less than the Length Tolerance parameter, the section is called steep. SURFCAM cuts the section with the other steep sections.
If the section is shallow and the section length is greater than the Length Tolerance parameter, the section is called shallow. SURFCAM cuts the section with the other shallow sections.
A part section between two shallow section is done in a like method.
