To update your InfraWorks 360 model with changes to a AutoCAD Civil 3D drawing

Objects brought into your InfraWorks 360 model from an AutoCAD Civil 3D DWG drawing can be updated to reflect changes in the AutoCAD Civil 3D source drawing.

If your InfraWorks 360 model is linked to a local AutoCAD Civil 3D DWG drawing, use the Reimport command to update the AutoCAD Civil 3D DWG drawing in your InfraWorks 360 model and reflect design modifications you have already made to the drawing in AutoCAD Civil 3D.
Note: If you added AutoCAD Civil 3D drawing objects to your InfraWorks 360 model using an IMX file that you exported from AutoCAD Civil 3D, the Reimport command is not available. Instead, you can delete the IMX file data source from the InfraWorks 360 Data Sources panel, export a newer version of the IMX file data source from AutoCAD Civil 3D, and manually re-import the newer version into InfraWorks 360.

To update your InfraWorks 360 with changes to the linked AutoCAD Civil 3D DWG file

  1. Click to open the Data Sources panel if it is not already open.
  2. Right-click on the AutoCAD Civil 3D DWG file data source.
  3. Select Reimport from the right-click menu.
  4. Note: Be careful not to confuse the Reimport command with the Refresh tool.

    Unlike the Reimport command, Refresh re-reads data currently stored in the model. You need to refresh sourced data whenever you change how the model is using sourced data.
