Civil objects are placed in the model using information defined in the civil reference data. Your first step should be to review the delivered reference data using the Catalog task. For more information, see Catalog User's Guide. You (or an administrator at your company) can create and edit customized civil reference data rules, symbols, and Microsoft Excel workbooks. For more information, see Civil Reference Data Guide.
After the reference data is customized to suit your needs, consider going to the Systems and Specifications task and defining the systems that you want in your model. While not absolutely required that you create your systems first, doing so keeps you from having to edit your objects after placement to assign them to the correct system. In addition, we recommend that you create your elevations and grids using the Grids task before placing civil objects.
After the reference data and the needed systems and grids are defined, you can begin placing civil objects in your model.
