Fabrication Data Manager (FDM) is a cloud hosted service that enables collaborators to share, manage, and build MEP fabrication content to deliver to Revit users. Content and fabrication configuration settings are defined within the cloud service and are available to Revit users for detailed modeling workflows.
Use Fabrication Data Manager to manage manufacturer-specific content to generate better estimates, create more accurate detailed models, and directly drive MEP fabrication. See the Autodesk MEP Fabrication Data Manager - Tech Preview - Help.
