Revit to Datasmith: Geometry Merging & Element Family Issues in UE 5.6

Hey everyone,

I’m hoping someone can help me out with a couple of issues I’m facing.

I’m working with a large Revit central model that includes over 20 linked files. For visualization purposes, I only need the architectural elements, so I’ve filtered everything in Revit and exported just the components I need.

The main issue is that when I import the model into Unreal using Datasmith, all the geometry gets merged into a single actor/mesh. I’d like to keep the elements separated for better organization and control during visualization—does anyone know why this merging is happening, or how I can avoid it?

Another problem I’m running into: I’d like to sort the different components by their element family, but instead of the actual family names, I just see “Linked Revit Model” as the element family.

For reference, my Datasmith export settings in Revit are:

  • Dimensions

  • Identity Data

  • Materials and Finishes

  • Phasing

  • Structural

I’m using Unreal Engine 5.6.

Any insights or suggestions would be really appreciated!

Thanks in advance!
