Chamfer

Declaration

class declaracad.occ.algo.Chamfer(parent=None, **kwargs)[source]

Bases: Operation

Applies Chamfer operation to the first child shape.

Attributes:
distance: Float

The distance of the chamfer to apply

distance2: Float

The second distance of the chamfer to apply

operations: List of edges or faces, optional

List of edges or faces to apply the operation to. If not given the first face will be used. Used in conjunction with the topology attribute.
