Now, you can export the coordinates of these COGO point as a Comma Separated text file, and use this file to create your toposurface in Revit. In this video, we will learn how to optimize and import dwg files into Revit. Here, make sure to set the Prompt for Description to Automatic, or you will have to type a description for every one of these point, which can be somehow tedious for thousands of points. Then, extract these points as simple AutoCAD points and convert them to COGO points.

To do so, you first have to change the style of your surface to display all its points. You can also import AutoCAD Civil 3D points directly in Revit.

I didn’t found any free plug-in to import directly LandXML in your Revit model, but if you are of the DIY type, you can use the example of code provided by Jeremy Tammik on his blog. The resulting Revit toposurface contains ten times less points than the version created from contour lines, which can be game-changing, especially if your are dealing with large or complex surfaces. Then use the Site Designer to import it back in Revit. Start by exporting your AutoCAD Civil 3D surface in LandXML. If you are a Subscription customer, you have access to the LandXML import from Site Designer, recently added to Revit. I often edit the image before inserting into the. Tracing over I usually use a color that I can see well i.e.: red on white. Revit creates a surface point along every surface contour, and rebuilts our surface. I pefer to insert the image into AutoCAD, scale the image, send the image to the back (draworder), turn off the frame, trace n then remove the image. In the Toposurface tools, I select the imported DWG, and check the layers containing these polylines. I use the Extract Object surface function in AutoCAD Civil 3D to transform every surface contour in a 3D polyline.īack in Revit, I import my surface as a set of 3D polylines following contours in my AutoCAD Civil Surface. Click on 'Create from Import' and click on the imported topography from AutoCAD. Now and finally go to Massing and Site Tab on the Ribbon and select Topo Surface. It all displays as it should and looks good but the propblem I'm facing is that I can't cut the imported drawing with a section in Revit. Go to Insert Tab on the Ribbon and select Link CAD (or Ipmort CAD doesn't seem to matter here) and browse to find the Topography file you saved from AutoCAD. But a Civil 3D surface object is not identified when imported in Revit. Hi, I have imported a 3D CAD drawing into Revit. My first impulse was to import the surface as a DWG, and use it to create my toposurface. I recently worked with AutoCAD Civil 3D and explored the various possibilities for creating toposurfaces in Revit from Civil 3D objects.
