I am a CAD manger for a small MEP firm in coastal NC. I have been the chosen to learn and implement Revit MEP 09 for our company. I have been going along pretty well, learning the basics. I have hit a snag with something that should be very basic. I have been following this Revit MEP 2009 Project Setup found here: http://www.revitgarage.com. I open the arch file, purge unused, then save the file. Then I start a new project (which confuses me as too which template I should use). I then link the arch file, and do a copy/monitor of the levels. The next step is to create new floor plans and then duplicate with detail. I can do this, but when I go to properties to change the discipline & sub-discipline, the sub-discipline option doesn't show up. I normally choose the default template. It works if I choose the mechanical or electrical template. My ultimate goal, is to have the central file set up so that it is ready for all three disciplines to start working without much effort. In the instructions I'm following, it says to create those new floor plans, but makes you wait until after you've created local files before changing the plans to their correct discipline. I'm really confused about how to approach setting up the central file for all three disciplines. Thanks for any help!
