34 | ---Purpose: Creates a Sphere at origin with Radius. The axes |
35 | -- of the sphere are the reference axes. An error is |
36 | -- raised if the radius is < Resolution. |
37 | raises DomainError; |

41 | ---Purpose: Creates a Sphere with Center and Radius. Axes are |
42 | -- the referrence axes. This is the STEP |
43 | -- constructor. |
44 | raises DomainError; |
