Create a solid sphere using one of several methods.
When you start with the center point, the central axis of the sphere parallels the Z axis of the current user coordinate system (UCS).
Sphere Creation Options
Use the following options to draw a sphere with the SPHERE command:
- Specify three points to set the size and plane of the circumference or radius. Use the 3P (Three Points) option to define the size of the sphere anywhere in 3D space. The three points also define the plane of the circumference.
- Specify two points to set the circumference or radius. Use the 2P (Two Points) option to define the size of the sphere anywhere in 3D space. The plane of the circumference matches the Z value of the first point.
- Set the size and location of the sphere based on other objects. Use the Ttr (Tangent, Tangent, Radius) option to define a sphere that is tangent to two circles, arcs, lines, and some 3D objects. The tangency points are projected onto the current UCS.
