Thank you very much Csongor!
Sorry, I didn't notice that option. Yes, the smallest pen setting works
wonderfully. All the indentations of the wall can be drawn at that scale.

Many thanks for developing this project, it is very nice.

I'd like to ask a small question please: can I drag the xvi across the
screen without zooming in and out? I tried combinations of Ctrl+drag,
Opt+drag but they didn't work. (I am using a Mac).

Thank you
Best,
Francesco
