Mansard roof in metric

[anablis]

Hi everyone, I need some help. I have my plan in metric units, but when I try to build a mansard roof, the help tutorial shows how to change the parameters--but in inches. Since I can't change from metric to inches in an existing plane, I need the parameters to build a basic mansard roof, but in meters and degrees. It was impossible for me to find those parameters... do any of you happen to know them or where to find them?
Thanks in advance.
