Template:Maya create polygons
From TOI-Pedia
You can create polygon primitives by using the create > polygon primitives command. It can be convenient to turn on Interactive Creation in the bottom of the polygon primitives menu.
When you now double click somewhere in your view port a primitive with the standard dimensions will be created. You can also create the dimensions of the primitive now interactively by clicking the required dimensions. This can work really well in combination with the snapping tools. If you don't want to use the interactive creation and you want every new primitive to appear at the (0,0,0) point in your view port with the standard dimensions, you can turn it off (and on) by clicking create > polygon primitives > interactive creation.
