Use one or more contours to revolve around an axis to either modify a relief, or to create a new mesh object.
In the image above, the left object is a relief modified by revolving a contour and the right object is a mesh created by revolving the same contour.
Parameters
When the Revolve command is activated, the Relief Dialogue will activate with additional parameters to define the revolve action.
Revolution Angles
Define the Start Angle and End Angle for the resulting relief or mesh. A complete revolution is 360 degrees and would have a Start Angle of 0 and an End Angle of 360.
A half revolution would use a Start Angle of 0 and an End Angle of 180.
The image shows a mesh object created with a Start Angle of 45 degrees and an End Angle of 135 degrees.
