Is there any (not so hard) solution to import 2D cad files into unreal asset?
I would like to use this for example landscape heights, extrude 2d shapes or for creating scenes along 2d plans.
Unfortunately I couldn`t found the way with Datasmith. It is buggy even with 3d dwg files(some 3d parts are not imported).
I am looking for the same. Joining the line.

Did you ever find a solution to this, I am having the same issue.

For linework I use the Blender Curves Importer plugin.
I export a DXF from Rhino with each curve on a separate layer. This step is needed because otherwise the blender DXF importer treats all curves on a single layer in your CAD software as a single object. You can separate the curves in blender in the edit mode with P, but I rather separate them by layers automatically in Grasshopper with the Wombat plugin (especially with a large number of curves).
Make sure you export the DXF curves as splines and arcs. Lines don’t seem to work for me (they don’t show up in unreal), but depending on the settings in your CAD software you may be able to export lines as splines (possible in Rhino).
The plugin comes with a Blender Exporter which outputs a .bcv file. The contents of the file are control points and spline handle points which are used to generate splines in UE. I haven’t tested the accuracy yet, but looks good.
It’s a bit of a hacky workaround but works decently well. I wish Epic will add support for importing splines from CAD data at some point.
If anyone has a better solution, please let us know.
