I don’t know how to check the phase in the linked model without accessing it. The linked model is linked directly from the Autodesk Construction Cloud, ACC, and I’m not allowed to access it. Don’t know if that’s what’s creating the problem?
@labrosse I misspoke in the comment above. We only load Rooms/Spaces from the host model. If you have all of the rooms modeled in the linked model, then you have to open that linked model. Otherwise, just place spaces in your MEP model on top of rooms. THat’s a typical MEP process.
