Creating Prisms

The prism is an n-sided, constant radius tube with n-sided planar faces on the ends of the tube.

To create a Prism:

• On the Command Panel, click on Geometry and then Volume.

• Click on the Create action button.

• Select Prism from the drop-down menu.

• Enter in the desired values for Height, Number of Sides and Radius.

• Select Circular or Elliptical.

• Click Apply.

Command

[Create] Prism [Height|Z] <z-val> Sides <nsides> Radius <radius>

Notes

• The radius defines the circumradius of the n-sided polygon on the end caps.
• If a major and minor radius are used, the end caps are bounded by a circum-ellipse instead of a circumcircle.
• The number of sides of a prism must be greater than or equal to three. A prism may also be created using the pyramid command with all radii set to the same value.
• If the Extended option is specified with Bounding Box, the result is a brick that is extended from a "tight" brick by the input percentage or absolute value.
• If a bounding box specification is used in conjunction with any of the other parameters (X, Y or Z), the parameters specified override the bounding box results for that or those dimensions.
