Sorting planar Line-like curves and curves

[r84crv (Raj)]

Hello, I am trying to figure how can we sort straight line and curves separately from a complex planar shape in grasshopper ? like in the ref. image below

I tried “Evaluate curve” and “Curvature” components but I guess they are useful to evaluate only on a particular point/parameter on the curve.

Basically, I am trying to sort curves with some curvature and the straight lines (with no curvature).

by sort you mean seperate.
sort is like 2 1 3 to 1 2 3
seperate is like 2 1 3 to 2 1 and 3
curvature is good

evaluation on curve mid point is enough in your case.
you do not neet do evaluate infinite points on curve.

for a more stable way:

you may want to use similar instead of equal depends on your curve.

ohh nice good to know this approach. Thankyou

Yes, wanted to seperate it according to the type. Thank you for sharing the two approaches. Good to learn these different logics.
