Plane

Rectangle—Creates the plane primitive from one corner to the diagonally opposite corner, interactively setting different values for length and width.

Square—Creates a square plane where length and width are equal. You can change dimensions in the Parameters rollout subsequent to creation.

See Creating Primitives from the Keyboard.

Length, Width—Sets the length, width, and height of the plane object. These fields act also as readouts while you drag the sides of the box. You can revise these values. Defaults= 0.0, 0.0.

Length Segs, Width Segs—Sets the number of divisions along each axis of the object. Can be set before or after creation. By default, each side of the plane has four segments. When you reset these values, the new values become the default during a session.

Render Scale—Specifies the factor by which both length and width are multiplied at render time. Scaling is performed from the center outward.

Render Segs—Specifies the factor by which the number of segments in both length and width are multiplied at render time.

Generate Mapping Coords—Generates coordinates for applying mapped materials to the box. Default=off.

Note: If a visible viewport is set to a non-wireframe or non-bounding-box display, Generate Mapping Coordinates is on for all primitives to which you apply a material containing a map with Show Map In Viewport on. If all viewports are set to wireframe or bounding box, 3ds max turns on Generate Mapping Coordinates for primitives containing mapped materials at render time.
