Rotation solids are created by revolving a 2D contour about a specified axis. Surfaces are generated along the contour to form the solid. This can best be illustrated by a few examples, which all show, from left to right, the 2D contour, the result after rotation in a cross-section view, and the resultant solid.
A wine glass:
Several different 3D objects can be generated from a single 2D contour by varying the segmentation and the angle of rotation.
Planter: On the left the contour and on the right after rotation with 24 segments and 4 segments respectively.
Baluster: On the left the contour and on the right after rotation by 360°, 180° and 270°, respectively.
