"Yeah, @robJYZMT, that one is unfortunate. Project should allow projection of multiple things, but today it is one-at-a-time. I will raise this issue in our next discussion to see if this behavior can be changed, but for now, the limitation exists."
What god damn morons. Every time I search to see if a common feature is in Fusion 360, a feature that might make each thing I try feasible, I find this exact same response. 'Gee saving the file... that isn't included as of the current release. I'll bring it up at the next meeting'. Often some clown developer follows the stock response with a 'the program works perfectly and you're stupid for not wanting to click 50,000 times to project every line and arc' sort of reply.
Maybe I aught to try solidworks at some point.
