How to Create a Single Closed Polygon in Maya
Polygons are the building blocks of polygon and subdiv objects in Maya. This topic shows how to build a single polygon using the Create Polygon Tool.
Using the Polygons menu set choose Mesh > Create Polygon Tool.
In one of the orthographic views (Top, Side or Front), click multiple times to define the object vertices. Click in a counter-clockwise direction for the object to be face-up. If your object has four vertices, hit the Enter key once you have clicked the forth point to close the object. Do not add your last point on top of the first point.
To build a polygon with square corners, consider using the Snap to Grid option while using the Create Polygon Tool.
The Create Polygon Tool options allow you to create objects with a specific number of points if desired.
