Create shape from selection, but normal information is not keept at vertex level

[Anonymous]

Hello there and thanks for reading!

So, I am intending to create a spline that is used to path deform a fence around a race track that holds different banking. Normals on the model (terrain) are fine, and by selecting the vertices (image one) everything is fine. However, when creating shape from selection (one of the road edges that goes alongside the complete track), the normal information on the vertex level is lost (image two). Is there a way to fix this? 

The version of Max I use is the latest of the 2016 versions. Also, triple checked that the pivot is set to local in all examples.

Another approach for making the fence is to create a line (or rectangle) with a length equal to the height of the fence and loft it along the spline.  You can then adjust its twist and teeter as necessary.
