Just found this amazing apps, installed and learning.

Not sure if I'm not doing it right or this feature is not there, what I want to do is to measure the distance between two walls, the trouble is whenever I moved a wall, the distance (in the menu bar, there's an icon for distance, that's the one I used). I tried to click the mouse when the blue line at the wall showed up, but if I moved the wall, the measurement remains in the same place, did not move with the wall.

Is it possible to make the distance move along the wall? If so how?
