How to datasmith 2D CAD lines into UE from Revit

Hi all, I have a Revit project with all the buildings modeled and landscape designed in 2D autocad lines. We use 2D lines for landscape to save time on the plans. When I try to datasmith export the Revit model into UE, all of the 2D information is lost. Therefore I cannot precisely locate the position of the trees/bushes/roads etc. Is there a way to see the 2D Autocad lines in UE after a datasmith export?
