extrude	Extend a 2-dimensional sketch through a third dimension in order to create new 3-dimensional volume, or if extruded into an existing volume, cut into an existing solid.	manual

Extend a 2-dimensional sketch through a third dimension in order to create new 3-dimensional volume, or if extruded into an existing volume, cut into an existing solid.

You can provide more than one sketch to extrude, and they will all be extruded in the same direction.

extrude(
  sketches: [Sketch],
  length: number,
  symmetric?: bool,
  bidirectionalLength?: number,
  tagStart?: TagDeclarator,
  tagEnd?: TagDeclarator,
): [Solid]

Arguments

Name	Type	Description	Required
sketches	[Sketch]	Which sketch or sketches should be extruded	Yes
length	number	How far to extrude the given sketches	Yes
symmetric	bool	If true, the extrusion will happen symmetrically around the sketch. Otherwise, the	No
bidirectionalLength	number	If specified, will also extrude in the opposite direction to 'distance' to the specified distance. If 'symmetric' is true, this value is ignored.	No
tagStart	TagDeclarator	A named tag for the face at the start of the extrusion, i.e. the original sketch	No
tagEnd	TagDeclarator	A named tag for the face at the end of the extrusion, i.e. the new face created by extruding the original sketch	No

Returns

[Solid]
