Only upload the 3d model of a 2D/3D Civil DGN?

Question

Hi, 
 
 We currently have OpenRoads, OpenRail and OpenBridge DGNs which have 2d and 3d models that upload into iTwin DR and create a mess when both the 2d and 3d models are included. 
 
 Is there any method to have a single model (ie. 3d model only) in a DGN file only get uploaded? 
 
 Regards, 
 Mark

Hi Mark, 
 I had the same though and after some testing, I have come up with this- Create a file with all of your necessary 2D linework to maintain the civil tool functionality such alignments, into one file. Then in the rest of your reference files keep them all 3D by only referencing the 3D model portion of the file. Reference everything into your container file as normal. This seemed to cut down on the unnecessary clutter for us. Hope this helps.
