Just added to the list.

Gonna toy with what would be needed to model skylights - it's actually not THAT complicated a roofing system YET which is exactly why I decided to have testers at this point in the construction.

BTW - when I've made changes I'm gonna upload another one for you all to play with - and just like before, it's yours free and clear - have as much fun with it as possible which will lead you to exactly the troubleshooting you've been giving me.

Thanks again!
