How to put OSB boards on the roof?? I have upgraded to D-roof premium, so it should be possible, right? I don't use the elementation module yet, even though I got that one also. First I don't think it will be an advance for the project I am working on now, secondly I don't have time to find out how the elementation module works.
But back to the question, how to put OSB boards on the roof??
