Sphere

Sphere constructs a spherical surface with a specified radius around a center point, or by using an existing circle as the 'equator' of the sphere you want to construct. Spheres are exact surfaces, but contain seams and degenerate curves at their poles.

To use Sphere:

1. Select Construct tab > Surfaces panel > Primitives > Sphere to display the Sphere dialog.
2. Optionally enter a Surface name.
3. Select a Construction method.
4. If Center and radius is selected:
   1. Enter the coordinates of the center point in the Center point fields, or click the Pick location button and select it in the graphics window.
   2. Enter the Radius of the circle.
5. If Circle is selected, select a circle from the Circle list or click the Pick circle button and select it in the graphics window.
6. Click Preview to display a preview of the surface in the graphics window.
7. Click OK.
