fillet	Function in std::solid	Blend a transitional edge along a tagged path, smoothing the sharp edge.	manual

Blend a transitional edge along a tagged path, smoothing the sharp edge.

fillet(
  @solid: Solid,
  radius: number(Length),
  tags: [Edge; 1+],
  tolerance?: number(Length),
  tag?: TagDecl,
): Solid

Fillet is similar in function and use to a chamfer, except a chamfer will cut a sharp transition along an edge while fillet will smoothly blend the transition.

Arguments

Name	Type	Description	Required
solid	Solid	The solid whose edges should be filletted	Yes
radius	number(Length)	The radius of the fillet	Yes
tags	[Edge; 1+]	The paths you want to fillet	Yes
tolerance	number(Length)	Defines the smallest distance below which two entities are considered coincident, intersecting, coplanar, or similar. For most use cases, it should not be changed from its default value of 10^-7 millimeters.	No
tag	TagDecl	Create a new tag which refers to this fillet	No

Returns

Solid - A solid is a collection of extruded surfaces.
