LebreCAD print scale formula

Hi all,

When I open a drawing in print preview it will scale the drawing automatically.  This scale is usually a decimal number such as 1:8.3487.  How does LebreCAD calculate this value?

Thanks in advance.

I'm not sure, but I think it just tries to fit the drawing onto the paper with a margin of a certain extent around the objects to the paper border. So you usually will have to set the exact scale manually.

Thanks dellus,

It's not really important, I'm just trying to figure it out.
