Drawing - diagonal measure

Hello!

I am drawing 4000x5960mm frame for cabin walls. Want to see measure from corner to corner diagonally. Then my buddy can check that before the frame is fastened on concrete.
Now when i try to put in point-to-point measure it comes vertically, not diagonally.
Am i doing something wrong?

Cheers,
Kai

Hi, you are not doing anything wrong :slight_smile: just select the dimension and set it to Absolute!

Thank you K-man!
