Here's an image to back up what Phil said. You can see the green cross-hairs at the bottom of the door. These can be positioned in 3 ways. 1. By typing values into the Joint Editor. 2. By using the dials which appear in each body part. 3. By using the mouse (last resort). If the door is a prop or combination of props, press ctrl-i to get properties and check 'visible' on 'display origin'. This will show you the same cross-hairs. mac PS The red cross-hairs can be ignored. The only affect the End Point, not the rotation.
