Hi,
While working with MEP families and components, I’ve noticed that retrieving MEP information (particularly connectors and related properties) from IFC files into Revit is quite difficult. It would be extremely beneficial if individual components—such as equipment parts, ports, connectors, and segments—retained their individual properties during the export and import process. This would allow for easier editing, assignment of properties, and proper modification of families generated from IFC files.
A fully functional Revit model with editable systems, such as ductwork segment by segment, would be ideal. However, it seems challenging to decompose all the MEP information into its respective connectors and parts.
I believe that the current IFC export from Revit may not fully represent a proper Building Information Model when this information is aggregated into a single element, especially in families, and lacks bidirectional export capabilities. For example, ducts are not handled as individual segments when imported back from IFC.
Furthermore, it’s unclear why IfcDistributionPorts often appear with empty information in IFC models, even though Revit contains the relevant connector data.
Is this something the Revit team could address to improve IFC interoperability for MEP components?
Thank you for considering this.
P.S. Tools like the mapping table do not seem to achieve these capabilities. For reference, see the mapping guide: IFC parameter mapping table or the different configuration features currently offered.
