Horizontal Curvature Drawing Taking time

Question

Hi, 
 I am working on a rail project currently where i need to recreate alignment of an existing railway line. I used regression tools for doing the same. I imported the survey data which has centreline of tracks as polylines. Converted poly line to Horizontal geometry. Then using option Geometry-> Utilities -> Assign Names, created points for regression. Added the points to Regression points and when i use "Horizontal Curvature Diagram Option" the PRT engine takes very long time and creates a diagram which is very much lengthier than the centre line. Can any one please point me out what is going wrong and the right way to do it.

Your regression points are mixed up. If you use View Regression Points you can see the network from your sorted line. 
 Try to add it from cogo points. 
 Use Import>Geometry chose Type: Cogo, and then in Add Regression Points set some properties like this: 
 
 Use your first 2 points for First point, and Second point :)

 You can see when I add your regression points from cogo, the sorted line consistently connect all the points:

Thank You Mr.Aleksandar. I had beforehand tried to add COGO points as regression points. but the result were the same. But now after your suggestion on changing the attributes in the advanced tab of " add regression points " dialog box, the result is perfect even when using the assign points option. The regression points are in correct order and the curvature diagram is also perfect. Thanks a lot.
