Versine calculation for 20 m chord

Hi all,

Does anyone know how we can calculate versine In Bentley rail. I will try to explain, I have a survey data x,y,z 800 pts for track center line. On basis of these data I would like to calculate versine for 20 m chord.

I give a sample:

Pt1 (5226558.25, 1254858, 500.11)

Pt2 (……………………….)

First step I calculated the pk, by using clearance calculations and now I want to calculate the versine in calculated Pks.

I tried to use horizontal regression -> slew diagram -> report. The problem is that Bentley calculates the versine by using the previous and the next point. And I want to calculate the versine for 20 m chord length.

I hope that I was clear.

Many thanks
