Circle

Is an initially 2D member of the mesh class of primitives. When adding this primitive, any number of vertices greater than 2 may be specified. So, any regular polygon from a triangle to, effectively, a circle may be added to a scene, faces formed if wanted, and then extruded. Primary use of a circle is probably as a cross-section that can, through vertex manipulation, be made into any shape for extrusion.
