Use this dialog box to publish Autodesk Civil 3D surfaces to Autodesk BIM 360 so they can be referenced into an Autodesk Revit model as a topography.
- Data Tree
-
Lists the Autodesk Civil 3D surfaces that you can publish.
Select the check box to the left of each surface that you want to publish.
Note: Grid surfaces and large surfaces cannot be published using this command and are filtered out of the selection. 
Expand All-
Expands the list of surfaces in the dialog box.
Collpase All-
Collapses the list of surfaces in the dialog box.

Pick From Drawing -
Specifies the surfaces to publish by selecting from the drawing.
- Specify Output File
-
Specifies the location for the published file. Select the BIM 360 location where you want to save the file and specify a file name.
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.
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.
