This video has a lot of gaps... check my latest video for more on T-splines (which still has gaps, but may be useful - the description of that video also has some useful resources on the topic)...

How to do stuff (mostly with T-splines) in Fusion 360... It's meant to be an "advanced" tutorial, but it's probably too basic for that. So... it might be too advanced for beginners, but not advanced enough for pros... intermediate maybe?
It may be too fast, but I hope it's helpful anyway.
