Everything you need is on the Tools menu. Go to Tools > Hierarchy View. This lets you setup the model hierarchy. Also you will need Tools > Adjust Object Centres. This lets you adjust the pivot point of each shape.

To "rig" the model, first move the pivot point of each mesh to where the center of joint rotation should be. For example, for a forearm, move the object center to the end of the mesh where the elbow would be. In the AC3D settings, be sure to check-mark "Rotate about object centre". This will allow you to test your joint placements. If they move correctly when you drag them with the rotation tool, you know you have the joint in the right place.

Next, you need to setup your hierarchy. Switch to Group Mode by pressing the button on the ribbon bar. Next, go to Tools > Hierarchy View. Group the model parts so that they form a logical tree, with the root joint of the body part at the head of each group. For example, if you were making a character, group the toe to the foot with the foot as the root; then the foot to the ankle; then the ankle to the thigh; then the thigh to the pelvis. Keep going until you have everything connected.

That should be all you need for most setups.
