I am hoping I am just missing something and work sets were not messed up in 2015! We work in multiple Revit models (one for Architecture, one for MEP, one for Structure) and we coordinate the naming of our worksets. For example Shared Levels and Grids gets a suffix for each model ( arch. is Shared Levels and Grids_ARCH). If in the arch. model we created a Shared Levels and Grid_MEP and turned it off we would no longer see the MEP Shared Levels and Grids and it would be a global "off switch" in the whole model, no need to go into each view template and shut them off. But it seems that in 2015 that is no longer the case???? Or am I missing something? If they have changed it that is going to suck! That was such a nice feature, and gave us the ability to turn off misc. things in one swoop.
