MX Rail User Migrating to Rail Track - Vertical Design

Hi,

I am an MX Rail user that is migrating to Bentley Rail Track and I have a problem with regards to the vertical design.

I have created my horizontal alignment and I have triangulated a surface model (based of existing contour information) to obtain the existing vertical profile along the alignment. However, when I try to place a vertical element (straight or curve) by snapping to a point within the vertical profile it returns a value of 0 for both the stationing and the level.

As mentioned I am use to MX Rail where the vertical alignment is produced in a different view within the software and it is possible to snap to points within the exisitng profile.

Any advice would be appreciated.
