Revit Link Civil 3D Published Surface

Before linking in the Topography from the published Civil 3D topography, the coordinates between Civil 3D were shared into Revit (Shared Reference Point).

In Civil 3D 2019.1, publish the surface. This may be found on the Collaborate or Output tabs.

Choose which surface to export or use the “Pick from Drawing” tool to manually select the toposurface in Civil 3D.

Click on the ellipses button to choose a folder and set a name for the export. Note, the “.shared” sub-extension is necessarily added to the file name (it is not possible to name it otherwise). It is published to the BIM 360 Connector so any other BIM 360 Design which means it is available to anyone else with access to the cloud platform.

A tin (triangular facets) surface is the most accurate representation of the Civil 3D data, but the warning may still appear. Here it is decided that “inaccuracies” will be tolerated. Here is a link to an Autodesk University class that is of interest to those that would like to have super accurate topographies created in Civil 3D appear in Revit (focused on techniques employed in Civil 3D to refine triangulation):

From within Revit, click on the “Link Topography” tool.

Note it looks for the topography in BIM 360.

Ignoring the warning that appears.

It can be seen how the topography is correctly position with respect to the site boundary.

The same view but from within Civil 3D.

Note the surface cannot be edited as per usual in Revit.

Building Pads interact with the Topography as per usual.

The phases and materials may be applied through the instance properties of the topography.
