Hi, I have the same issue. I used to use Chief a lot at a former job (a much older version) and since I did mostly interior work you would draw a box and then what I want to do is be able to click on a wall and when the dimension comes up be able to change it. The problem is its set to exterior dimension not interior dimensions. In the old version you would click on the dimension tool>locate objects and there was a combination of walls and wall options you would click to make this happen. I have tried every combination and it still just shows the dimensions to the outside of the wall. Any help would be appreciated.
