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:
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 MEP 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, expand Families, and navigate to the affected family type. Right-click the family type, and click Rename.
