This is exactly what I did. I have only had to convert the distances measured on a real apartment to the absolute wall corner coordinates. The latter took some effort with the calculator, especially assuming the unknown real wall thickness

Anyway, thanks again!

Thanks!

The dynamic grid is actually a good feature, but might become quite disturbing, when I have to place the wall corners into the exact coordinates according to the plan. With low zoom I cannot see, whether I have placed the point correctly, and when I zoom-in, the grid dynamically decreases ...

The grid changes as you zoom in and out.

Is there an option to set a fixed non-automatically-adjustable grid for the wall and object placement and to control it manually?
