Hi, This (I know) will be so basic for you guys (and galls) but I have spent a week on this with no success!

I have a set of plans for a balsawood model aeroplane I wish to build.

1. From the ‘Model’ or ‘Sheet 1’ sheet – how do I select a specific part and put it on a new sheet so I can print it?
2. If the part is say 2” x 3” how do I get it printed to scale?

Many thanks in advance for any help for this old fool (I certainly feel like one)!
