There are several ways you could impliment this. The method I prefer for making architectural props is to maker figure with no geometry, then parent the various props to that, and resave it to a figures palet. For doors, the first thing to do, before you position them, is to set the Y origen (the hinge). The general rule is to lock any channel (by setting the limits) that is inconsistant with the movement that you want. For example with a sash window you would lock all the rotation channels, and all the translation channels except for yTran. For a door you would lock everything except yRot.
