Need help to connect points along a surface

Hi all,

Does anyone know how to connect two point along a irregular surface? I was looking for a node including surface (surface), start point(point), end point(point) as inputs and curve as an output, but I couldn’t find it in Dynamo. Can anyone help me in it?


Curve.ByParameterLineOnSurface seems to be what you’re looking for.

Thanks Andreas for the tip. Please correct me if I’m wrong. I assume this node connect points on a surface along the surface , right (e.g., Figure 1 & Figure 2)? The issue is my points do not belong to the surface. I have a list of points in two sides of a surface (Figure 3). Do you think still I can use this node?
