I have been using Rhino for some time in model railroad design – locomotives and cabooses primarily – but my needs and abilities are still quite modest. Currently I am designing an outdoor model railroad that includes “mountains” meaning I need to be able to draw a line representing the track and have a percentage grade assigned to it so it rises or declines in the z dimension.
Ideally I would like to take a curving line in the X-Y plane, indicate a start point and a percentage and have the line rise or fall by that percentage through the end point. I thought of using Setpt and then connecting the points but that seems like a slog.
I would be grateful for any ideas or assistance. Oh, and Happy Holidays to all.
