Thanks, Merv. I actually worked it out. Intead of trying to adjust with the nudge tool when the dynamic dimensions showed a zero value, the value was not actaully zero. I decided to click on the dim and manually set it to zero and the wall snapped in alignment. Apparently, my problem was a tolerence setting in the dimension set up. Depending on the rounded value set even if only 1/16″, it may be that you get a “0” reading in a tight condition using dynamic dimensions. So “0” could be whatever the closet rounded value is. in my case, it was just enough to offset the wall face I was trying to align creating a seam when viewed with a 3-D camera.
