To Publish Surfaces to Autodesk BIM 360 to Reference into an Autodesk Revit Model

To prepare for publishing surfaces to BIM 360

You can publish Autodesk Civil 3D surfaces to Autodesk BIM 360 so they can be referenced into an Autodesk Revit model as a topography.

To publish an Autodesk Civil 3D surface to BIM 360, you first need to install Desktop Connector for Windows. You also need to be a member of a BIM 360 project.

1. Follow the steps in Prepare Autodesk Desktop Connector in the Autodesk Revit Help to install Desktop Connector for Windows.
2. If you are not already a member of a BIM 360 project, ask your BIM 360 account administrator to add you to a project. See Access BIM 360 in the Autodesk Revit Help.

To publish surfaces to BIM 360

1. In Civil 3D, click Output tab Export panel Publish Surfaces to display the Publish Surfaces dialog box.
   Note: The Publish Surfaces command is also available on the Collaborate ribbon tab and on the Surfaces contextual ribbon tab in the Extract From Surface drop-down.
2. Select the TIN surfaces that you want to publish.
   Note: Grid surfaces and large surfaces cannot be published using this command and are filtered out of the selection.
3. Under Specify Output File, click the browse button and navigate to the BIM 360 folder to use. Select a BIM 360\<hub>\<folder>\<subfolder> location.
   Note: The Publish Surfaces command requires that you specify a location within a BIM 360\<hub>\<folder>\<subfolder> location. A connected drive for BIM 360 is indicated by a icon. An account within the connected drive is indicated by a hub icon . A folder is created within a hub.
4. Specify a file name and click Save.
   Note: By default, the file will have the same name as the current drawing name and will be saved with a .shared.dwg file name extension. For example, if drawing1.dwg is the file name, by default the file will be saved as drawing1.shared.dwg. The surfaces that you specify are all saved in the same file. When you link to the topography in Revit, all of the surfaces in the file are linked.
5. Click OK.

   If the surface style settings need to be modified to ensure an accurate surface representation in BIM 360 and Revit, a task dialog box is displayed.

6. Click Publish the Surface with the Updated Style to automatically update the style and to continue the publish operation. The surface style in the current Civil 3D drawing will remain unchanged.
Note: If you need to repeat the publishing operation using the same file name and location, it is recommended to wait for about one minute before republishing so that the previous process can be completed first. Note that the processing time depends on the size of the surface.

To view published drawings on BIM 360

You can view and manage your published drawings in your BIM 360 account.

For more information, see About Document Management in the BIM 360 Help.

To reference surfaces in a Revit model

To reference the surfaces in a Revit model, you link to the drawing file that was published from Civil 3D. The surfaces are referenced into the Revit model as a topography.

• In Revit, click Insert tab Link panel Link Topography .
