Hi all! Long time fan, long time lurker!

Just recently I bought CC3 and although I love it I've been struggling to learn it.

I've watched all the video tutorials on the internet, and although they cover pretty much everything, there is something I just can't make.

I'm mostly making battlemaps for printing and using miniatures. This one particular map would be an alley fight, on a medieval city. I was thinking behind a building, some boxes lying around, some debris. Thing is, I don't know how to do the buildings! There are no houses in CC3 (I've got SS1 and 2), and the ones in the CSUAC don't seem to fit.

Could you guys point me to some tutorials on that, or provide me some tips?

Thanks a lot!
