revolve Rotate a sketch around some provided axis, creating a solid from its extent. manual

Rotate a sketch around some provided axis, creating a solid from its extent.

This, like extrude, is able to create a 3-dimensional solid from a 2-dimensional sketch. However, unlike extrude, this creates a solid by using the extent of the sketch as its revolved around an axis rather than using the extent of the sketch linearly translated through a third dimension.

Revolve occurs around a local sketch axis rather than a global axis.

You can provide more than one sketch to revolve, and they will all be revolved around the same axis.

revolve(
  sketches: [Sketch],
  axis: Axis2dOrEdgeReference,
  angle?: number,
  tolerance?: number,
  tagStart?: TagDeclarator,
  tagEnd?: TagDeclarator,
): [Solid]

Arguments

Name Type Description Required
sketches [Sketch] The sketch or set of sketches that should be revolved Yes
axis Axis2dOrEdgeReference Axis of revolution. Yes
angle number Angle to revolve (in degrees). Default is 360. No
tolerance number Tolerance for the revolve operation. No
tagStart TagDeclarator A named tag for the face at the start of the revolve, i.e. the original sketch No
tagEnd TagDeclarator A named tag for the face at the end of the revolve No

Returns

[Solid]
