chamfer	Cut a straight transitional edge along a tagged path.	manual

Cut a straight transitional edge along a tagged path.

Chamfer is similar in function and use to a fillet, except a fillet will blend the transition along an edge, rather than cut a sharp, straight transitional edge.

chamfer(data: ChamferData, solid: Solid, tag?: TagDeclarator) -> Solid

Arguments

Name	Type	Description	Required
data	ChamferData	Data for chamfers.	Yes
solid	Solid	An solid is a collection of extrude surfaces.	Yes
tag	TagDeclarator		No

Returns

Solid - An solid is a collection of extrude surfaces.
