We are an electrical engineering firm working on our first Revit project, we are using Revit MEP 2008 and the architect we are working with is using Revit Architecture 2008. I found an awesome tutorial here about the project set-up procedures and I used that to get us started, everything worked great! Now the Architect has posted an updated model and I went to update the model thats linked into our project, well there are some issues now. I wanted to know if anyone can tell me the basic steps to update the linked model? In AutoCAD it was just a mater of making sure the update was the same name and overwriting the old background, simple, Revit seems a bit more complex. Any suggestions and help is greatly appreciated! Thanks to all, for your time and help!
