How to load corner windows @Archicad 11 and how to show hat.

[Anonymous]

I'm a kind of beginner for Archicad 11. I used to use Archicad 7 and our office has upgraded recently to Archicad 11. I'll have bunch of questions which might be really simple or basic. I need your help about how to load corner windows(now I can use only empty corner window) and how to show hatch pattern on the wall at elevation drawings.
