Amiga @karol_urb buenas, I see what your problem is, I will try to express myself correctly if you generate points in dynamo the internal properties of that point come with default properties that is to say without any rotation, while if you ask for a Curve. CoordinateSystematsegmentLength along a curve this node access to the internal properties of the point on the curve, and I think that’s what you are looking for I leave you an example, if you want to start working with alignments and C3D own objects I advise you to download 3 packages Civil3DToolkit, Camber and Arkance Systems, the creators participate in the forums and there are many post about how to use their nodes and what they are used for!
