What I mean by laying out a vertical curve, is starting with the PVI and bisecting the length (L)of the curve in equal distances to both the PVT and PVC, and then calculating the vertical offsets (d) from the incoming tangent through the length of the curve to establish the vertical curve centerline elevations.
If I use VectorWorks to create a Bezier curve with the starting point at the PVC and the end point at the PVT, will the offset elevations equal the parabolic curve elevations as would be calucated above?
In summary, we are looking for a way to use VectorWorks for engineered road alignment as an alternative to Autodesk's LDD.
Thanks for your help.
We really appreciate it.
