To provide context for the building, link topography from the civil engineer to the Revit model.
This video demonstrates the following:
When collaborating with a team member who is using Autodesk Civil 3D for the site design on the project, you can link their topography surface into your Revit files. The linking functionality is enabled for projects using Autodesk Docs workflows. Before you use Link Topography, be sure you have the Autodesk Desktop Connector installed, and you and the team member using Civil 3D have access to the same Autodesk Docs project.
The workflow starts in Civil 3D where the surfaces of the site design are created. Once the TIN surfaces are complete, on the Output tab, click Publish Surfaces. In the dialog, select the surfaces you wish to publish. Grid surfaces and large surfaces containing more than 1 million points are filtered out for the selection. Browse to the Autodesk Docs location, give the file a name, and click Save. Click OK in the task dialog to publish the surface.
You can view the published surface on Autodesk Docs to verify the accuracy of the surface.
Once the surfaces have been published to the Autodesk Docs project, you are now ready to link the topography into the Revit model. First, open a view where the topography category will be visible. In this example, we open a 3D view. On the Insert tab, click Link Topography. In the dialog, navigate to the Autodesk Docs location where the surfaces were published from Civil 3D, and click Link.
The link is positioned using the Auto - By Shared Coordinates setting, aligning the incoming geometry's origin (World Coordinate System) with the shared coordinates of the Revit file (survey point). If the incoming file does not have geolocation information, center-to-center positioning will be used instead. If the incoming geometry is composed of multiple surfaces, each surface is a separate topography element.
Topography links can be worked on similar to a native Revit toposurface in order to continue to develop the design.
The design may also continue to be developed in Civil 3D. If changes made in Civil 3D are published to Autodesk Docs, the link can be reloaded in Revit LT to reflect the changes. On the Insert tab, click Manage Links. In the Manage Links dialog, select the Topography tab. Linked topography files are listed here. Select the updated topography, and click Reload. The linked toposurface file in the Revit model is updated to reflect the changes published to Autodesk Docs.
