23 | class Chamf3dDimension from AIS inherits Relation from AIS |
24 | |
25 | ---Purpose: A framework to define display of 3D chamfers. |
26 | -- A chamfer is displayed with arrows and text. The text |
27 | -- gives the length of the chamfer if it is a symmetrical |
28 | -- chamfer, or the angle if it is not. |
