I am retopoing a ton of skulls and fossils that have many occluded nooks and inner parts. Is there any way to hide a selected area in a reference mesh so I can retopo the inner parts a bit easier?

Actually I found it, it is called "rotate", in some of the older documentation, found through google, it called "spin" specifically, thus is hard to find for a noob one day in. Much faster than Add/Split Edges tool method. I am really surprised this also did not make it into the first few intro videos on YouTube playlists I tried, nor on Plural site. If you, as a professional modeler, have never uses this "spin" or "rotate" function in any of the packages, you should try it, it will speed up your workflow, edge-flow and efficiency on organics. Maybe, I should not be trying to learn a new software on a deadline, makes me grumpy, sorry about that.

Just bought the software. Watched hours of tutorials. Cannot find a way to spin edges, searches yielded nothing. This is a must have for any professional modeler. Seems very strange this is not an easily accessed tool.
