Project Model Co-authoring

Infrastructure Project Model Co-Authoring using Civil 3D and the ACC 


Task 1: Accept a project invitation to access projects 

  1. A project admin needs to invite you to the project
  2. Once you have been invited, you will receive this email, click ‘Go to your project’ to access the ACC project site. 

  3. You are now added to the project
  4. The project admin may also need to grant you folder permissions 


Task 2: Model the project in Civil 3D 

  1. Create a drawing in Civil 3D
  2. Click the Civil 3D Icon at the top left corner of the screen
  3. Select ‘Save As’ in the drop-down

  4. Navigate to the Autodesk Docs location using the Autodesk Desktop Connector

  5. Save the file 


Task 3: Setup Shared Coordinate Point in Civil 3D 

  1. In Civil 3D Toolspace  
    • Toolbox  
    • Subscription Extension Manager 
    • Autodesk Shared Reference Point  
    • Export Shared Reference Points for Autodesk Revit 
    • Right Click on Export Shared Reference and click ‘Execute’ 

  2. Select the initial basepoint and then select a second point at the same elevation. When selecting both points, keep in mind that they will need to be selected in Revit as well. 
  3. Select Units (Defaults to Meters every time) 

  4. A prompt to save an XML will come up. Save the File to the project location in Autodesk Docs. 

  5. Click ‘Save’ 


Shared Reference Point Utility is a separate download in versions before 2022, from 2022 forward, the add-on is installed OOTB. See documentation HERE for further information 

Task 4: Create Data Shortcuts in Civil 3D 

Set Working Folder Location 

  1. Right-click on data shortcuts in the Tool Space Palette 
  2. Select “Set Working Folder” 

  3. Set working folder to point to a folder within Autodesk Docs.  

  4. Click ‘Select Folder’  

Create Data Shortcut Project Folder 

  1. Right-Click on data shortcuts in Tool Space palette 
  2. Select “New Data Shortcut Project Folder” 

  3. Add in required information and click ‘Ok’ 

  4. If you have an existing Data Shortcut project folder, you can click ‘Set Data Shortcuts Project Folder’ and pick the location.  
  5. Associate project to current drawing by right clicking on Data Shortcuts in the Tool Space Palette and click ‘Associate Project to Current Drawing’


Create a Data Shortcut 

  1. Right-click on data shortcuts in the Tool Space Palette and select “Create Data Shortcuts” 

  2. Select necessary data and click Ok 


Task 5: Create Data References in Civil 3D 

  1. Navigate to Data Shortcuts in Tool Space (Working folder and Project Folder should already be set from the last step) 
  2. Right-click on the Data Shortcut you want to reference and select “Create Reference” 

  3. Enter in required information in ‘Create {Surface, Alignment, or Profile} Reference’ dialog box and select ‘OK’ 



Additional Information 

Publish Surfaces to Autodesk Docs to Reference into an Autodesk Revit Model 

To publish surfaces to Autodesk Docs 

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 Autodesk Docs folder to use. Select an Autodesk Docs\<hub>\<folder>\<subfolder> location. 

Note: The Publish Surfaces command requires that you specify a location within an Autodesk Docs\<hub>\<folder>\<subfolder> location. A connected drive for Autodesk Docs 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 Autodesk Docs 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 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 .
