Creating Spherical Surfaces

You can create surfaces in the shape of a sphere. The spherical surface is based on a center point, an axis-system defining the meridian and parallel curves orientation, and angular limits.

Before you begin: Create a 3D shape containing a point and an axis system.
  1. From the Surface section of the action bar, click Sphere .
  2. In the Center box, select the center point of the sphere.
  3. In the Axis box, select an axis-system.
    This axis-system determines the orientation of the meridian and parallel curves, and therefore of the sphere. By default, if no axis-system has been previously created in the document, the axis-system is the absolute axis-system. Otherwise the default axis-system is the current one.
  4. Click Preview.


  5. In the Radius box, enter the radius value or use the arrows to modify the radius value.
  6. In the Limitations Type, do one of the following:
    • Click <icon> to specify the parallel angles and meridian angles as required.

      Important:
      • Parallel angular limits are comprised within the -90deg and 90deg range.
      • Meridian angular limits are comprised within the -360deg and 360deg range.
    • Click to create the whole sphere based on the center point and the radius.

  7. Click OK.
