I would like to read blueprints of my house in Adobe Illustrator. I know, this app is not designed for that purpose, but forget about that for a moment.
I would like to measure distances on the blueprint, but when I import the plans of my house into Illustrator, then the size of the blueprint won't match with the reality. I can't use the Rulers of Illustrator, because there is no nice scaling factor between the imported blueprint and Illustrator's ruler. I need to scale the blueprint to match the distances on the plans.
Is there a way of scaling compound objects by declaring the size of it's sub-objects? Let's say, there is a window hole on the blueprint, who's width I know, and I would like to scale everything by declaring the size of a line that represents the window hole.
