Procedures

To create a Pyramid:

On the Create menu choose Standard Primitives Pyramid.
Choose a creation method, either Base/Apex or Center.
Note: Hold the key while using either creation method to constrain the base to a square.
In any viewport, drag to define the base of the pyramid. If you're using Base/Apex, define the opposite corners of the base, moving the mouse horizontally or vertically to define the width and depth of the base. If you're using Center, drag from the center of the base.
Click, and then move the mouse to define the Height.
Click to complete the pyramid.

Base/Apex: Creates the pyramid base from one corner to the diagonally opposite corner.
Center: Creates the pyramid base from the center out.

Width, Depth and Height: Sets the dimension of the corresponding side of the pyramid.
Width, Depth and Height Segs: Sets the number of segments to the corresponding sides of the pyramid.
Generate Mapping Coords: Generates coordinates for applying mapped materials to the pyramid. Default=on.
Real-World Map Size: Controls the scaling method used for texture mapped materials that are applied to the object. The scaling values are controlled by the Use Real-World Scale settings found in the applied material's Coordinates rollout. Default=off.
