Hi,  
I’ve got a problem with the node “Springs.Collector.ElementSketch” from the package “Springs nodes”.  
I need to extract the length of sketch path in a model in-place. For an extrusion by sweep, when I use the command “sketch path”, the node give me the right result but when I use “Pick Path”, the node return “Empty List” or wrong values.

Is it possible to modify the Python’s script to do this?

Could you please document your request so it appears clearly that no other solution to this issue can be found despite a significant effort to solve it? Thanks 🙂

I’ve joined Dynamo script in my post to test. Unfortunatly, I don’t use Python and I didn’t know other node that it can return the sketch of object.  
To understand the problem, look at the vidéo and below
