7 | class BeanFaceIntersector from IntTools | |
8 | ||
9 | ---Purpose: The class BeanFaceIntersector computes ranges of parameters on | |
10 | -- the curve of a bean(part of edge) that bound the parts of bean which | |
11 | -- are on the surface of a face according to edge and face tolerances. | |
12 | -- Warning: The real boundaries of the face are not taken into account, | |
13 | -- Most of the result parts of the bean lays only inside the region of the surface, | |
14 | -- which includes the inside of the face. And the parts which are out of this region can be | |
15 | -- excluded from the result. | |
