Prism
Use Prism to create a three-sided prism with independently segmented sides.
Procedures
To create a prism with an isosceles triangle as its base:
- Choose Isosceles on the Creation Method rollout.
- Drag horizontally in the viewport to define the length of Side 1 (along the X axis). Drag vertically to define the length
of Sides 2 and 3 (along the Y axis).
(To constrain the base to an equilateral triangle, press Ctrl before performing this step.)
- Release the mouse, and move it vertically to define the height of the prism.
- Click to complete the prism.
- On the Parameters rollout, alter the length of the sides as needed.
To create a prism with a scalene or obtuse triangle at its base:
- Choose Base/Apex in the Creation Method rollout.
- Drag horizontally in the viewport to define the length of Side 1 (along the X axis). Drag vertically to define the length
of Sides 2 and 3 (along the Y axis).
- Click, and then move the mouse to specify the placement of the apex of the triangle. This alters the length of sides 2 and
3, and the angles of the corners of the triangle.
- Click, and then move the mouse vertically to define the height of the prism.
- Click to complete the prism.
Interface
Creation Method rollout
- Isosceles
-
Draws a prism with an isosceles triangle at its base.
- Base/Apex
-
Draws a prism with a scalene or obtuse triangle at its base.
Parameters rollout
- Side (n) Length
-
Sets the length of triangle's corresponding side (and thus the triangle's corner angles).
- Height
-
Sets the dimension of the prism's central axis.
- Side (n) Segs
-
Specifies the number of segments for each side of the prism.
- Height Segs
-
Sets the number of divisions along the prism's central axis.
- Generate Mapping Coordinates
-
Sets up the required coordinates for applying mapped materials to the prism. Default=off.
