Import AutoCAD Civil 3D data into Autodesk InfraWorks 360 using an .IMX file format.
Consult the AutoCAD Civil 3D documentation for further instructions.
To export to IMX from InfraWorks 360, see Export to IMX.
Each feature class will appear under its respective category in the Data Sources list. For example, imported surfaces will appear under Terrain.
Click the entry under Type and select an appropriate entry. For example, select Pipelines if you are importing pipes, Roads if you are importing a corridor, or Terrain if you are importing a surface.
Generally, InfraWorks 360 can position the incoming data automatically, based on the data itself.
For information on setting options for AutoCAD Civil 3D roads, surfaces, and corridors, see Importing From AutoCAD Civil 3D.
A tooltip displays at the top of the right-click menu for the data. For more information, see Create Tooltips During Data Import.
You can have only a single ground surface in each model, but you can use proposals to show different surfaces. For example, create one base ground. Then create a proposal and import a second surface within that proposal, containing the proposed ground. Switching between the proposal and the master version will change the appearance of the terrain.
If you change the coordinate system, make sure to specify the coordinate system of the incoming data (not the coordinate system of the model). If the imported data uses a different coordinate system than your model uses, InfraWorks 360 will transform the data to the model's coordinate system, without changing the original data store.
