So this one is a short one but a hidden gem as no one seems to teach this in training and most people don’t find it until they accidentally click the little blue square grip on the temporary dimensions witness lines.¬† You can toggle between center of wall and face of core/finish (depending on how you have the temporary dimensions setup) by clicking — instead of dragging — the small blue square grips on temporary dimensions.

Also demonstrated in this video.

You can also drag these grips to other reference within that wall or to another reference point (this is where weak and strong references in your families come into play!).  As always, hope this helps.  Leave comments and have a great day!
