Create a mesh sphere using one of several methods.
When you start with the center point, the central axis of the mesh sphere parallels the Z axis of the current user coordinate system (UCS).
You can use the Mesh Primitive Options dialog box to set the default number of divisions for a mesh sphere.
After a mesh primitive is created, the current level of smoothness for the object can be modified.
Mesh Sphere Creation Options
The Sphere option of the MESH command provides several methods for determining the size of the mesh spheres you create.
- Specify three points to set the size and plane of the circumference. 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 diameter or radius. Use the 2P (Two Points) option to define the size of the sphere anywhere in 3D space. The plane of the circumference is parallel to the XY plane of the UCS, and the Z value is determined by the Z value of the first point.
- Set the location to be tangent to two objects. Use the Ttr (Tangent, Tangent, Radius) option to define points on two objects. Depending on the radius distance, the sphere is located as near as possible to the tangent points you specify. You can set up tangency with circles, arcs, lines, and some 3D objects. The tangency points are projected onto the current UCS. The appearance of tangency is affected by the current level of smoothness.
