If it's a prop you're talking about, you can simply press ctrl-i for properties and check 'display axis'. Or you can open the Joint Editor (alt-w-j). Then all you need to do is set the axis on one side of the door and on the correct edge. You can do this by dragging the green cross with the mouse, by using the dials or the Joint Editor. It's always best to use the Orthographic cameras, like Front, Left and Top for greater accuracy in positioniing the JPs (joint parameters). One more tip. Once you have the door set up, find the correct amount of rotation. It'll be something like minimum 0 / maximum 120 degrees, or for a door which opens outwards, the reverse - min-120 / max 0. Then double-click the rotation dial name and, in the dialog box, type the maximum and minimum limits. This will ensure that it doesn't crash through the walls. (Remember to turn on Use Limits in the Figure menu). mac
