You can create spheres. The latitude lines of a sphere are always parallel with the xy plane of the current UCS; the central axis is always parallel with the z-axis. You position a sphere by specifying its center point. You determine the size of a sphere by specifying either its radius or its diameter.
To create a sphere as an ACIS solid
1 Do one of the following to choose Sphere (
):
• On the ribbon, choose Draw 3D > Sphere (in Draw 3D Solids).
• On the menu, choose Draw > 3D Solids > Sphere.
• On the Draw 3D Solids toolbar, click the Sphere tool.
• Type sphere and then press Enter.
2 Specify the center of the sphere.
3 Specify the radius or diameter.
To create a sphere as a Facet Model mesh
1 Do one of the following to choose Sphere (
):
• On the ribbon, choose Draw 3D > Sphere (in Facet Model Meshes).
• On the menu, choose Draw > Facet Model > Sphere.
• On the Facet Model Meshes toolbar, click the Sphere tool.
• Type fmsphere and then press Enter.
2 Specify the center of the sphere.
3 Specify the radius or diameter.
