I am new to revit, and I am having issues connecting the plumbing on a larger project. The fixtures are on the architectural plans and I have linked that file to the mep project I am working in. However when I go to attach a pipe to the fixture, it doesn't recognize the fixture. How do I fix this?
You cannot connect to a fixture in a linked model. It's a limitation of the program. You will have to place a similiar fixture into your mep project and connect to that. Also there is a copy/monitor function in Revit MEP that would copy the fixture from the arch model into the mep model but I've not had much luck with it.
We have "dummy" fixtures with nothing more than a hot/cold water line connector, waste drain and vent connectors placed at the right height for the fixture. We insert those and then connect away.

Here's a couple of connector-only families that some nice person from Autodesk University 2009 shared with everyone. Feel free to use these or modify them to your needs.
