jbwilliamz Posted November 4, 2008 Posted November 4, 2008 Having never worked with them before, I have been asked to look at some information about them? Anyone got any quick references about how to draw them? Maybe some links? Cheers guys, Jb Quote

Cheers guys, Jb it would still be somewhat similar to drawing a road on a flat plane. basic requirements on road width, ditches, minimum turning radius, PC(Point of Curve), PT(point of Tangent), PI(Point of Intersection). But you will have an addition of maintaining the slope of the road with respect to elevations per stationing, especially at the curves. Civil 3D a powerful tool in layouting roads along rolling terrains. Quote
CarlB Posted November 4, 2008 Posted November 4, 2008 A method to simply draw a vertical curve (parabola) was posted by me in this thread. http://www.cadtutor.net/forum/showthread.php?t=5248 ...which I learned from Mr. McSwain. There have been a few lisp routines posted as well, which you could find if you do a search for "vertical curve" or "parabola". Quote
rustysilo Posted November 4, 2008 Posted November 4, 2008 Here's an Excel sheet that calculates vertical curves. vertical curve.zip Quote
