CAT muscles provide a way to simulate flatter rows of muscles.

Tutorial: Adding muscles to a rig
In this example, you take the default human character rig and add a CAT muscle to the front for the chest
and stomach definition.
To add muscles to a rig, follow these steps:
1. Open the Human char with muscles.max file from the Chap 39 directory on the DVD. This file
includes the default CAT human rig.
2. Open the Create panel and choose the Helpers category and the CAT Objects subcategory. Click
the CAT Muscle button and drag in the Front viewport to create a CAT muscle that runs from the
collar bone to the pelvis on the left side. Then move the muscle plane into position in front of the
ribcage bone.
3. Open the Modify panel and set the U and V Segs values to 15. Select and move the outer corners
and their adjacent handles to make the muscles bend around the side of the body.
4. Select Create ➪ Extended Primitives ➪ Chamfer Box menu and drag to create a box with rounded
corners. Then create and elongate a sphere object with the Create ➪ Standard Primitives ➪ Sphere
menu. Position the rounded box at the location of the pectoral muscle. Position and clone the
sphere to show three rows of stomach muscles.
5. Select the CAT muscle object, and in the Modify panel click the Add button for the Collision
Detection section and select the rounded box and sphere objects. Then move the collision objects
to create the desired muscle look in the CAT muscle.
