How to Extrude Polygon Faces in Maya



Starting with a simple polygon object, you can extrude the faces to add more geometry. This technique is quite helpful in creating a basic structure that can be converted to a subdivision surface to create a smoother, more organic shape.


Step One

Add a polygon cube to the workspace. Set the x, y and z divisions to one. (Create > Polygon Primitives > Cube).

Step Two

Switch to the Component Mode and activate the Face Selection. To select the top face, click the center of the face.

Step Three

Choose Edit Mesh > Extrude. Notice the arrows and scale boxes now available.

Step Four

Click and drag the arrows (to move) or the scale boxes (to scale) the new geometry.

Press g to accept the change and begin another extrusion. To exit, press the q key to return to the Select Tool.

Extruding to Create a Character

The Extrude tool is a great way to extrude outward to create arms, legs and fingers for a character. You can also extrude inward as you work on a character's ears, nose and eye sockets.
