Coming from a background in Catia, one thing I seemed to ALWAYS use, especially in large assemblies, was the ability to toggle on or off visible/hidden workspaces. This is important primarily with large assemblies as you start to hide surfaces, bodies, components/etc searching thru all those drop downs becomes extremely tedious especially if its a small patch, or screw/etc that was hidden for CAM/etc.
I'd love to just be able to toggle visibility to see everything that is currently hidden then show or select what I need that's hidden then toggle back to my visible view as normal. This would be ideal if it were available over all workspaces, but primarily the Model and CAM.
Attached is something I've been wanting to make for a while. Found a decent model but has over 60 components. I've hidden a couple parts of the main housing, but none of the components are named they just have a part number. Right clicking the body hides the body not the component so now I need to go thru every single component and open it, then open bodies to see if its turned off which is going to take way too long most likely. This is just one example of why this would be beneficial.
