How to rotate the axis in the coordinate system?

Hi 

I am trying to rotate the coordinate system plotted on a polyline using ByDistanceAlongCurve. For some reason, the cyan axis(Z axis) is not pointing in the right direction. 

In this case, the cyan axis should be pointing where the green axis is point to.. I am unsure how to make this work. Any building content which I try to map it to this node, picks up the orientation of the X,Y and Z node which comes up as incorrect orientation.

Building content aligning itself to incorrect orientation.

Thanks,

Rohini
