You may encounter this warning when using Copy/Monitor to monitor changes to MEP fixtures.
Warning: The loaded type has been renamed to avoid conflicts with the existing type.
Issue: This warning occurs when all of the following conditions are true:
- Fixtures were copied from the linked model to the host model.
- The mapping behavior for a fixture category was defined as Copy original.
- In the linked model, the fixture is host-based.
- The host model already contains a family type with the same name.
When copied, the host-based fixture type is automatically converted to a face-based fixture type in Revit. (The geometry of the original fixture family is copied to a face-based family in Revit.) This conversion enables easier hosting of these fixtures on surfaces in linked models.
To avoid conflicts with the existing family type, Revit creates the face-based fixture type with a different name.
Solution: No action is required.
If desired, however, you can change the family type name. In the Project Browser, navigate to the affected family type under the Families node. Right-click the family type, and click Rename.
