Thanks -- you guys are the best! I'm glad this was an interesting challenge -- definitely wasn't something I'd ever run across before.
I want to watch the videos and take the time to understand what you guys did to create this doorway. But I'm pressed for time on this project, so for now I just grabbed David's beautiful symbol and ran with it. :o See the beautiful result in the attached image.
Now I have to figure out how to put a roof on this baby. Roofs are not exactly my strong suit either (did I mention I do RENDERINGS???), but you learn by doing -- and I'm learning a lot! But I may be yelling for some more help soon. :)
