Fabrication detailing in Revit supports different MEP detailing workflows.
For each fabrication model, you must specify a fabrication configuration and load services.
You can then place parts to create a detailed fabrication model in Revit. You can also convert an existing Revit model with generic duct, pipe, and electrical containment parts to a model that uses fabrication parts.
Continue to add fabrication parts and modify the elements in the model as needed.
