Jeff,
Sorry I didn't see your question earlier. I did some work on some DC cabinets a few of months ago. I wanted a cabinet whose door could be set for either a right-hand or left-hand door swing. The method I worked out was to create two doors, only one of which would be visible. There's a "Door Swing Direction" parameter which can be set for either a right or left swing. Making a selection unhides the approprate door and hides the other. Each door's rotation parameters adjust for their individual rotation axis. Perhaps not the most elegant solution, but it seems to work fairly well.
Each door's rotation formula actually contains both a rotation AND a translation component - so that it works the way modern, higher quality hinges work.
The DC also lets you adjust it's width, as well as extend the drawer.
Good luck,
Frank
