Intersecting points - 2 Rail data points

Revit
1

Hello,
I was hoping somebody could steer me in the right direction. I have been give a data file (excel) of points (4 x points per 1m spacing) that

  • I have been able to get into Dynamo
  • Separate out the bottom points
  • Then find the centreline between the two rails. For which a polycurve has been placed
  • Then divided centreline to have a 700mm spacing for rail track sleeper placement.

My issue or question is… now how do I place a line or points from the 700mm spacing points I have placed on the rail track centreline back to the outer rails? and to be at the correct normal’s around curved sections.

Any advice would be much appreciated.

Hello Kulkul,
Apologies for my crude sketch. Unfortunately the data I have received only has a 1m spacing for a rail track profile and they are unable to export data at the sleeper spacing of 700mm so I though that’s a good job for dynamo!. But now I have hit the brick wall trying to get the points or line back to the outer rails.
Regards
Dan
