I made horizontal and vertical alignment, complexed by elements ( lines, curves).
Then, when i display in 3d, what i got is 3d polyline of multi-lines.
How can i get a 3d model with full properties as i made in profile ( curve's radius, start/end point,...).
I tried export to V8i or dwg, but they still.
Please give me some experiences.

Simple answer - you can't.
It's not a failing of ORD. Mathematically, it can't be done.
Think of a circular curve. A circle, and any other conic section, is planar by definition. The plane can be defined in any orientation. If you look at it from any other orientation it will appear distorted, elliptical. The circular curves in your alignment are defined on the XY plane. If you apply your vertical alignment to that circle, it is no longer a circle (unless the alignment is parallel to the XY plane).
ORD - just like InRoads, Geopak and MX before it - displays the alignment in 3D by creating a linestring with vertices that match the definition of the alignment. The line segments between the vertices approximate the location of the alignment.

Thank you Ray.
It makes sense.
