There are some commands when it becomes really annoying that rhino wants to use mesh edges as a selection when asking for a curve.
Two examples are QuadRemesh and SplitMeshwithCurve. For quadremesh you might be picking a flow/direction curve, and on a dense mesh you end up picking a really tiny edge.
Just a thought,
Yep, I know - I’ve run into this as well. I am not sure what the answer is - though I believe SplitMeshWithCurve was tuned up. RH-64395 SplitMeshWithCurve: Edge could be selected as cutting curve

Would there be any plan to add it to quadremesh? Although, I guess it makes sense to keep it since people might want to use mesh edge loops to feed into guide curve selection.
