I have spent quite a lot of time in the Autocad environment, and one of the things I really like is the layer handling. AutoCad has layer states and the difference between that and layer scenes, is that the states among other things remember if a layer is editable or not. Right now I'm sitting with a document from a venue - by default. they have 30+ layers before even drawing anything. It would save a lot of time for me to be able to go between Scenes, but I would be even faster if I had the option to include all layers to my scenes, also the ones I don't want editable. Also, AutoCad dims the locked (not editable) layers - quite nice too. Am I missing something? Is it already possible maybe?
