Chamfer definition mode.
A chamfer between two faces can be defined using two lengthes,
or a length and an angle.
The first length, or the single length, depending on the way the
chamfer is defined, is measured on the reference face from the
edge to chamfer
to determine the first edge the chamfer creates on the reference face.
This reference face is either the face selected or the face
determined by CATIA if the edge to be chamfered was selected.
The second length, or the angle, determines the second edge that the
chamfer creates on the second face.
Values:
catTwoLengthChamfer
The chamfer is defined using two lengthes
catLengthAngleChamfer
The chamfer is defined using a length and an angle
