Thanks again for the encouragement, always appreciated. Sometimes I tell laypeople "I made it on a laser" and they're underwhelmed because they think its like Star Trek-- you tell the computer what you want, the lights go blinky blinky and the desired object pops out a little door. The the nice thing about sharing projects and ideas with you guys here is we all know it ain't quite that simple.
Here's part of the next building. I had to think about awhile before a solution came to mind, really pleased with the results.
