If I use Layer Combinations, then I could have a layer combination for example "Turn all layers on". When I create a LC I have to setup every layers status for that combination. When I create a new layer I need to set that status in every combination (ok for that)
But, lets say I have a group of layers I often need to turn on / off, for example a constructionxref. I can't do it with the help of LC, because a LC set status of every single layer, not just a few of them.
I'm not sure how to explain in other way. Don't ask me why I work in this way, but in some project I don't have a choice and in almost everyone of those project this function would help me alot.
I'm not sitting in the sketchingpart of projects, I'm the man that builds BIM-models of sketchmodels most of my time (if there isn't any complex forms, then I'm working with sketches too) and connect architectures and constructions together and need to turn on / off layers alot when I build my models.
