Hi Scribibble1!
First off, thank you so much for the support.
Second -- thank you very much for taking the time to offer your thoughts on how to improve this. I hadn't thought of a "one shot" spray-it-all, but it's certainly doable -- I will consider it.
Zoom/ In and out is possible using plus and minus keys works in construction steps. (Or am I missing something?)
Regarding rotation -- you are correct -- the model is on a virtual turntableand it's that that rotates -- but now the you point that out... I wonder why I built it that way? Lol. I will definitely revisit this -- having the model camera rotate around the center of projection would be much more intuitive and less clumsy.
Sopwith Triplane would make an interesting subject!
Thanks again,
