Creating a Polygon with a Hole
Maya 8.0 Tutorial
How to Create a Polygon with Hole in Maya
It is quite easy to create a simple polygon by using the Create Polygon Tool. By default a closed polygon shape has a solid face.
This technique is handy for creating 2D polygon shapes with holes.
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, click each of the four points. Do not press the Enter key.
Holding down the Ctrl key (Mac or PC) click the first vertex that defines the hole. Release the Ctrl key and click the remaining hole vertices.
When you have clicked the final hole vertex, press the Enter key. This object may now be given depth using the Extrude tool (see topic, Extruding Polygon Faces).
