I do not have the whole answer but I do know from some recent posts here that in order to land on a building it has to be made that way some option you have to set. Sorry I can not be of any real help here my only sugestion would be to see if the program you are using will allow that option. From what little I know about AOW I was under the impression that it was a simple program with out a lot of bells and whistles, it was a means of creating buildings without a lot of trouble. If this is the case than you might not be able to make that kind of a building using it. But like I said I really do not know but I am sure others will.
