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.

Revit creates a surface point along every surface contour, and rebuilts our surface. 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. But a Civil 3D surface object is not identified when imported in Revit. My first impulse was to import the surface as a DWG, and use it to create my toposurface. With Civil 3D + InfraWorks + Revit + Navisworks you can improve site and building design coordination with shared coordinate systems.I recently worked with AutoCAD Civil 3D and explored the various possibilities for creating toposurfaces in Revit from Civil 3D objects. Civil 3D + InfraWorks enables you to connect design to detailed engineering. Civil 3D + InfraWorks + Revit enables you to tackle integrated bridge design and analysis. Use Civil 3D with other Autodesk software to expand your capabilities. You can work with ArcGIS data directly in your Civil 3D design model and ensure that teams maintain access to up-to-date project information. With Civil 3D you can integrate GIS data in Civil 3D. Advance Your Workflows with GIS Integration Project teams use BIM 360 Design to streamline deliverables coordination, visualize changes, and manage issues and markups, all in a common data environment throughout the life of the project. Using Civil 3D, infrastructure professionals can improve project delivery, reduce risk, errors, and omissions, and respond faster to design changes.
