Tutorial AutoCAD Civil 3D Surface to Revit Toposurface

[@PT0B]

Thank you for this. What a nightmare this has been before watching this video. Even if it doesn't work out perfectly in some cases, you can snap topo points to the surface!

I've been seeking this so long, great work, very useful.

Very good! I wondered what I did wrong, but then you reminded me of visibility/graphics. Thanks, now it works

Excellent video - do you have a video in regards to setting up the elevation ?

I am here to support Sir. Have a nice day

Thank you, it was really usefull

Really worked, thanks!!!

Hey, is it possible to create a triangulated Toposurface in Revit? The Topo created through hight lines is not so accurate compared to the Civil Site. Thanks for Help

Hello ! Thanks for sharing your knowledge with us. Is it possible to download the excercise file: Civil 3D surface & survey model.dwg ? Thank you in advance !

Great video . . . . .Does not work in Revit 2024 / 2025 . . . . . . .

@@itatabisine6250 it will work for Toposolids. Toposurfaces have been replaced

@@RevitStructureBlog Yeh, I know that, but because of that, it completely misreads the CAD file and adds new triangulation of the surface. In particular, we have a case where we have a flat surface that meats a sheer cut in a site, followed by another flat area. Revit interprets this scenario by adding new points where the sheer cut is and creates triangulated 45deg batter.

@@itatabisine6250 I do know that there is a point limit of 10k. I have found that splitting a TIN surface and building the solid in separate parts helps

@@RevitStructureBlog thanks for the tip. I'll try that approach! Cheers ;)
