Thanks Seppo!

really nice question 'Are you sore?'

Wasn't with intention. On next version will be "Are you sure?" [:(]
TODO also in next version:
- implement somehow the exterior walls;
- to align exterior dimensions;
- to add walls thickness.
At that moment, to align dimension lines, I don't see other solution than select the lines and than align them with another plug-in.
I will see what I can do or maybe someone else could do this.
