Road design (RD)

Road design is mostly an SDK which helps you design the plan and profile of a road, using either the properties and methods of the Road class or by using a simple but effective editor.

It was not meant to be a road design software alternative, but instead a tool for creating or re-creating a plan in order to use it for volume calculation, analysis, cross section computation, tunnel or railway simulation.

It's written entirely in .NET (Visual Basic, still can be used in C# or any other .NET language), source code is also available on demand.
