GC for OpenRoads


I am trying to use GC in ORD. I managed to reference the alignment and to import it as a "Polyline" and I want to project it onto a plane to be able to access chainage values. I have inserted a "Curve" node with the "ProjectCurveOntoPlane" technique, selected the "Polyline" from previous step and "baseCS.XYPlane", however, it throws the stop prohibition sigh with "Check Alignment of Curve" comment.

I have tried with alignment and with a polyline generated from alignment with 0 (nil) offset and no transitions.

I am using ORD 2021 R1(bis).

Any help much appreciated. Thank you in advance.
