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(
  solid: Solid,
  length: number,
  tags: [EdgeReference],
  tag?: TagDeclarator,
): Solid

Arguments

Name	Type	Description	Required
solid	Solid	The solid whose edges should be chamfered	Yes
length	number	The length of the chamfer	Yes
tags	[EdgeReference]	The paths you want to chamfer	Yes
tag	TagDeclarator	Create a new tag which refers to this chamfer	No

Returns

Solid
