Thanks Jim for the work-around. I've definitely commanded the pieces to the "0" position using XYZ "=0". I essentially fixed the problem with Cotty's method of re-doing the local origins of the components.
However, not that the pieces are back I wonder if you guys can offer info for scaling. I'd like to door to be able to scale & move pieces to fit a cabinet. Meaning, if I change the width of a cabinet, I want to tell the program to move the left & right stiles, and the scale the rails to fit the new width. Similarly, if I change the height I want SketchUp to move the rails to fit & scale the stiles to their new heights.
Could use some genius on this issue!
