First, you need to parent the doors to the body of the cabinet so that they are "locked" to it. Then display the origins for each of the doors (ctrl+i) and, using the dials, move the origins to the very edge of where the doors meet the cabinet-body. you may want to move the centres of origin to the middle of the width of the door as well. Then set up your rotation using the dials (rename the dial that actually opens the door to open) and delete any unwanted dials using CR2 Editor by J Stallings. Then select the body of the cabinet and save as a prop - including the doors. Paul
