How do i do this?
I have to replace wooden sleepers over a bridge and I have survey points on both left and right side of each sleeper set out on the bridge deck (see attached drawing).
I need to know the distance between the bridge deck level and the TOR level.
New centre line (horizontal and vertical) and Cant are known and the offset is unnecessary.
The clearance report returns the distance to the vertical design and not vertical + cant design.
How can I get information for inner and outer rail?
Thanks

As a quick answer that should work but isn't maybe the best.
The above solution doesn't work well because COGO points must match the station interval of the reference alignment. Not possible.
Another one is to import the rail as alignment and use also the clearance report between the rail (as alignment) and cogo points.The style sheet to use is VerticalClearanceToCogoPoints.It looks ok but you don't have the station of the centerline
The Clearance Report .xml has the following:
- <ClearancePoint firstOffset="0.099140414" projectsToAlignment="true" origin="point">
<offsetPoint name="ml16" style='Default' northing='315444.833867798' easting='320768.803463344' elevation='0.000000000' pointType='Cogo' />
- <centerLinePoint instantaneousRadius="-590.000000000" instantaneousGrade="0.00000000000000" tangentDirection="1.953177794084" radialDirection="3.523974120879" cant="0.095000000" widthAlong="0.095939861" heightAbove="-0.053671360">
- <point northing="315444.925848160" easting="320768.840455706" elevation="0.000000000" offset="0.000000000" pointType="POC" type="POC">
<station internalStation="100299.985226339" externalStation="100299.985226339" externalStationName="" />
</point>
</centerLinePoint>
</ClearancePoint>
So you have the centerline station, elevation, cant and curvature (i.e. signed radius)
And you have the cogo point's name and elevation.
So with a little bit of style sheet development, you can get the vertical offset from the rail to the survey point. The style sheet will use the centerline radius to determine whether to add 1000.0 * cant (I am assuming metric with the 1000.0 ) to the centerline elevation or not.
