- AndreLester commented on C.a.R.
Quite an amazing piece of software with a relatively friendly user interface. It can export to SVG and I see it's native file format is XML. Not ideal but much better than some binary format. It should be quite easy to read the geometries from 3rd party software if the need arises.
As my first project, I simulated the horizontal alignment of a highway. One can move the tangent lines and/or adjust the curve's radius with a slider with the geometry updating in real time.
Job well done....

Job well done. This software needs more love.
