This is an easy question. How can I stretch a wall a certain distance from a point. I am typing the distance but it doesn't work properly it seems it goes to the coordinate of the number I type instead of moving that point the selected distance.
You can add and substract numbers in the tracker. So if you start stretching element, move mouse to the other element height you want to match, then type the number and press '+' on keyboard to add it. This will take in to account whatever number is behind decimal marker.
This works for anything in tracker (moving, stretching, offset, etc etc) and I find it very handy.
