There are several different ways to share coordinates between disciplines. If you are working on a site/ landscape that does not have a building and you want to link in MEP, that can simply be done via Origin to Origin. This is how all of the building disciplines (Architecture, Structure, and MEP) link together by default and it is why Shared Coordinates are only necessary when you get out on to the site.
But if you are working with building-based MEP (or Structure), coordinates will need to be shared. If you have all of your building files (architecture, structure and MEP), then you could link them all into the site using the Site to Architecture workflow for all building files. However, this requires that all building links be moved and rotated to the correct location all at the same time. There are 2 big problems Continue reading
The trick to coordinating with any other discipline in Revit, is to get them to maintain a view for you. Or at least have that view setup in their file, so you can go and clean it up as needed. This is often what happens with architecture, not because they are necessarily worse at maintaining their view, but because it takes more effort to filter the multiple categories that consist of the building shell (with MEP, if I have them turned on at all, it is only to see a few pieces of equipment or connections).
In our Architectural template, there is a view that they use to export down to dwg (if needed) and it is also the view that we look at in all of our plan views. Shown below are the typical Revit Link settings: view filters, view range, and model categories are all by linked view. Annotation categories is custom and all turned off (just to be safe, though technically there shouldn’t be any annotations).
