I recall experiencing this issue with the very first Revit DS release, and I’m still seeing it here. Workflow is below:
- Open a Revit model and export the building as FBX, then also export it as a Datasmith file.
- Load the Revit Datasmith file into UE4.
- Import the FBX exported into step1 into 3ds Max, then export a Datasmith file from Max.
- Import the 3ds Max Datasmith file and the position and orientation doesn’t match what came from Revit. The building is always flipped 180 degrees on the Z axis.
Any thoughts on this? Don’t know which one I should trust, Max or Revit.
