Civil 3D and Revit are the cornerstone products in Autodesk’s BIM strategy. Let’s take a look at how we can import a Revit model into Civil 3D 2011.
The content of this post comes from a white paper written by Dino Lustri, one of our Civil 3D specialists. Dino is a licensed engineer and surveyor in our Cleveland office.
You need to use the ADSK (not RVT) file format to import Revit data into Civil 3D. With Civil 3D 2011 open, use the Import Building Site command from the flyout of the Import panel of the Insert ribbon tab.
This opens the Import Building Site wizard. Locate the ADSK format file you want to import.
Once you’ve found the file, click the< Next> button to confirm the units.
If you are unable to make any changes on the Confirm Units page, it means that the units and zone are set correctly in the drawing. If they are not set, enter the required units and zone for your project area. When you have finished, click the <Next> button to proceed to the Display Properties page. On this page, verify that the layer and style are set properly, then click the <Next> button to proceed to the Insertion Point page.
When on the Insertion Point page, leave the coordinates to the default values that came with the ADSK file. The Revit user should be designing in real space in their software. If you receive a file that does not have coordinates, you will have to select these manually by selecting the Specify in Drawing checkbox and entering the correct coordinate information. Sometimes, even though the Revit file is at the correct location from the Architects point of view, you may need to adjust it in Civil 3D to account for a setback or property line. Click the <Preview> button to see how the inserted content will look. If everything looks good, click the <Finish> button to complete the import.
You will now be able to see the Revit ADSK object in Civil 3D.
That’s it for this session. Next, we’ll look at exporting a Civil 3D surface object for use in Revit.
