Plane intersect (Can't see my planes)

I’m trying to create intersect points from one curve to another by using planes, but it doesn’t work in my way. Can you explain what is my problem and how can I solve it?

You might take a look at your List.Levels.
Can you upload the picture again where you’ve expanded the List.Create list?

Thank you for your response! I didn’t quite understand which extension you mean, but I hope this is it.

See if Geometry.Intersect works better
