Civil 3D Boundary is not showing correctly when imported to Revit

[Anonymous]

Hello Revit community,

Any idea why I am getting this warning below: 

It happens when I link CAD from Civil 3D to Revit. Image below shows aside from the boundary (PINK LINES) I created, it also generates the whole toposurface although I did not select it from the list. I only want to see the boundary surface.

Thank you in advance, cheers!

Regards,

Richie

I don't know if I understand correctly, but it sounds like you want to create a Split Surface (on the Massing & Site Tab).

Hi @barthbradley,

I already tried that but error. See below:

And I am not sure if this is the proper way to do it. Or maybe I am doing it the wrong way. I dunno if it has something to do with Site Settings.

Thank you for the reply @barthbradley.

Cheers!

Thank you for your posting @Anonymous

Have you tried to import through Site Designer? Try this and see if you can get more accurate result.

the boundaries can't touch each other. Modify one of them.
