I don't think this feature exists, but it's completely necessary for designs with tons of parts: Folders in the Bodies and Sketches lists. See attachment. I'm building a fairly simple shed, but there are enough studs, rafters, panels of sheathing, etc. that I need to be able to organize them into groups so I can quickly turn things on and off. Selection groups work well for turning things on and off in groups, but the list of bodies in my design is so ridiculously long that scroll it is a PITA. 🙂
Love Fusion 360! Keep up the great work!
