Creating Hemispheres

The Hemisphere tool creates hemispheres using one of three modes.

Mode
Description

Radius

Defines the base of the hemisphere by radius

Diameter

Defines the base of the hemisphere by diameter

Up Radius

Defines the base of the hemisphere by center and rotation

The hemisphere radius can be changed with the Reshape tool (see Reshaping Extruded Objects and Solid Primitives), the radius can be modified from the Object Info palette, and the resolution can be adjusted through the 3D Conversion Resolution setting (see 3D Preferences).

To create a hemisphere by radius:

  1. Click the Hemisphere tool from the 3D Modeling tool set, and select the Radius mode.

  2. Click to set the center of the hemisphere base.

  3. Move the cursor to the desired radius and click to set the radius of the hemisphere base. The radius can also be set in the Data bar.
