Overview

This section describes the Files submenu options. These options allow you to open a road design file, and specify default design parameters.

The road design file consists of layers containing a type of road design data. Refer to the Data Structure section for information on the structure of road design data. Associated with the road design file is a default design parameters file (<proj><design_name>.ron). These parameters relate to alignment, intersection points, super elevation values and slope of batters. Additional default parameters, such as topography, subsurfaces, label size, bulking factor and haulage costs can also be set.

If you don't specify design defaults, then system defaults will be applied. These defaults are automatically put into the .ron file. See Appendix A for a default design parameter file containing system defaults.
