Absolutely! Although there are so many that deserve our appreciation, I’d especially like to thank Dave R. for the depth and breadth of his contribution to the community - both here and for so many years at Sketchucation. It’s hard to count the number of people that he’s helped and the number of issues he’s helped resolve. (not to the mention the Dave method!)
I’d also like to acknowledge the incredibly useful (and clever) methods and tutorials that Box constantly comes up with. I’ve learned so much about efficient and creative modelling from watching and working through his many gifs.
And, not to forget the plugin authors whose generous (and mostly free) contributions have made Sketchup the infinitely useful 3D tool that it is. Special thanks to Fredo6, TIG, ThomThom, Chris Fullmer, Didier Bur, Whaat, and SamDMitch.
