Use the Spheres panel to create a spherical surface and/or mesh.
Examples
Creating a full spherical surface
Center is selected.
|
The sphere is created.
|
|
Using the four points option
Nodes are selected.
|
The sphere is created.
|
|
Using the user-controlled option
Points are selected.
|
The sphere is created.
|
|
Subpanels and Inputs
The Spheres panel contains the following subpanels and command buttons:
Panel Inputs
Input
|
Action
|
center
|
Select a point for the center of the sphere.
|
meshing options
|
| • | mesh, keep surf: creates a surface from the selected entities and then generates a mesh on the created surface. The created surface is retained along with the mesh. |
| • | mesh, dele surf: creates a surface from the selected entities and then generates a mesh on the created surface. The created surface is then deleted and only the corresponding mesh is retained. |
| • | mesh w/o surf: This option creates a mesh between the selected entities using linear interpolation without creating a surface. |
| • | surface only: creates a surface from selected entities, but does not create a mesh. You can use the resulting surface to perform any desired geometry cleanup functions or automeshing. |
|
radius
|
Enter the value for the radius of the sphere.

Action
|
center
|
Select a point for the center of the sphere.
|
r
|
Pick the nodes that represent the point.
|
angle
|
Pick the nodes that represent the point.
|
angle type
|
The angle type determines how the angle node orients the sphere.
theta: zero degrees for theta starts on the vector created by center to angle and theta spins in the plane created by center, r, and angle. Theta follows the right-hand rule, and starts at the normal of the plane created by the three selected nodes.
Phi: follows the right-hand rule. Phi follows the vector created by center to r and spins in the plane created by center, r, and angle.
