Create a Revolved Surface

Create a Revolved SurfaceCreate a surface by revolving a curve (or surface edge) around an axis.  Start and end angles may be entered according to the right-hand rule of positive rotation, as determined by the direction that the axis line is defined.

tog_minusNotes

1.The direction of definition of the axis line is important because it determines the right-hand rule of positive rotation for the start and end angles of the revolved surface.

2.The curve's (or surfaces edge's) existing position defines the zero degree position for angles.
Here is an example doing a partial rotation from 20 to 100 degrees.
