Track transition curves/Easements (= Euler spirals)
Actual railway uses Euler spiral for curves transitions. I would be nice to have an assistant to draw them in RMP
- From Radius,
- To Radius,
- Overall angle.
New type of parametric flex track to model transition curve (easement) as sequence of curve segments, each with decreasing radii.

Johan commented
Yes I agree - for serious planning of realistic model trains that would be really nice
-
Euler spiral segments could either
- be approximated with a cubic Bezier curve - a new parametric flex track in addition to the straight and curved types could be an option to offer track transition curves.
- a new kind of track featuring a sequence of curves with progressively increasing radii.
