Stuck in Wire frame after cad file drape

Hi, I have just learnt how to geo locate, import terrain and drape a cad file onto the terrain.
However my model is now stuck in wireframe and does not respond to the face style commands.
Could this be an easy fix?

If they’re dashed lines, then maybe try unchecking back edges.

It could be an easy fix but it might not be, too. Can you share the file? Generally 2D CAD files don’t import with faces.

Thanks for replying…
The file is too big to upload. I’ve cleaned it up and made components of all I can, but still to large. I think you are right about the CAD file having no faces though.
Suspect I will have do do more CAD training before I can move forward!

Hi, Back edges wasn’t checked. Think I’ve just got a lot more learning to do!
Thanks for your response.
