SPH4, XCENTER, YCENTER, RAD1, RAD2
Creates a spherical volume anywhere on the working plane.
XCENTER, YCENTERWorking plane X and Y coordinates of the center of the sphere.
RAD1, RAD2Inner and outer radii (either order) of the sphere. A value
of zero or blank for either RAD1 or RAD2 defines
a solid sphere.
Defines either a solid or hollow spherical volume anywhere on the working plane. The sphere must have a spatial volume greater than zero. (i.e., this volume primitive command cannot be used to create a degenerate volume as a means of creating an area.) A sphere of 360° will be defined with two areas, each consisting of a hemisphere. See the SPHERE and SPH5 commands for other ways to create spheres.
When working with a model imported from an IGES file (DEFAULT import
option), you can create only solid spheres. If you enter a value for both RAD1 and RAD2 the
command is ignored.
