appearance	Set the appearance of a solid. This only works on solids, not sketches or individual paths.	manual

Set the appearance of a solid. This only works on solids, not sketches or individual paths.

This will work on any solid, including extruded solids, revolved solids, and shelled solids.

appearance(data: AppearanceData, solid_set: SolidSet) -> SolidSet

Arguments

Name	Type	Description	Required
data	AppearanceData	Data for appearance.	Yes
solid_set	SolidSet	A solid or a group of solids.	Yes

Returns

SolidSet - A solid or a group of solids.
