MEfitting.BypointsAndCurve node

Continuing the discussion from Problem with MEP fitting by point and curve node:


I am having a problem with MEfitting.BypointsAndCurve node. It returns a null value
I am collecting radios for valves from an excel file. Then I input pipes (which I have created before) and the centroid for those pipes.

Any suggestion to correct this ?

Thank you very much!![image|690x375]


Try flattening your lists.

Could you show preview for Pipe.ByLines node.
