Hi all. I have a bounch of 2 d lines running along a railtrack, that I would like to convert to a 3d element. I need to able to give the line some minimum bend radius, and also a minimum offset from a terrain model so I can ensure having a certain amount of cover, while not bending the element more than the minimum bend radius of 4 meters. I can't get my head around how I would create such rules, and apply them in order to create a 3d element that has a minimum of 0,5 meter cover and stays above the 4 meter radius. All must be created on behalf of the terrain model.
I tried playing with that a bit, I think I need to read up on what those parameters actually do
I do not use BRT, but if it has the Civil Tools > Vertical Geometry tools, you could use see if 'Define Profiles by best fit' [R 3] would give you what you needed (or at least get very close to requirements). It has options for upper and lower envelope, Desirable crest and sag length, and minimum curve length.
I’m considering doing it in GIS software instead, since rail track stutters with terrain models of this size. And I’m more on home turf in the GIS software. But it does seem like a big roundabout
I am using powerrail track SS4, and was hopping there was a way to append rules and achieve a 3D line that copy x, and y cords from the 2d line, and get z cords from the terrain model based on the rules of minimum distance below terrain and the minimum radius of 4 meters
What software are you using?
