Profiles

Profiles are stored within .pro files, with user-defined names.  Existing Ground/Surface Profiles and Proposed Finished Grade/Design Profiles both use this filetype.  Multiple .pro files can be drawn on the same Profile Grid.

There are several different routines for creating profiles including Profiles From Triangulation Files, Profile From Surface Entities and Profile From Points On Centerline. Before using these profile creation routines, the horizontal alignment needs to be created as a centerline file or polyline. The Quick Profile routine can be used to create profiles in one step.
When using Process Road Design or RoadNet, the existing ground Profile can be generated automatically as part of the process, simply by specifying the Surface to use, and so is not a separate prerequisite.  The Proposed Finish Grade Profile can then be added in the editor, and the Roadway processed, all without ever drawing anything in the drawing itself.  The more traditional LDT approach of generating an existing ground Profile in the drawing and then adding a proposed finish grade Profile by drawing on it in the drawing is also an option.
