Nstocks,
There are 2 ways to print at a specific scale....
From SketchUp:
-Set your camera settings to parallel projection and find the view you want to print out.
-> With this setting ON, your print options menu will now have fields available to you to allow for printing at different scales of your choice.
From LayOut:
Chose your paper size.
Embed your model into the paper space and set your embedded model to parallel projection and find the view you want to print out.
-> Under the SketchUp Model menu, chose your scale from the dropdown menu.
I hope this helps
