Domain of polyline

[Ramon_Weber]

I have noticed that when inputting Polylines (that are drawn manually in Rhino) into grashopper the EvalCurve component sometimes gives different results than the divide, or a combination of splitting and recombining the curve. Why is that ?

Is the domain of a polyline linear?

Hi all! While i was trying to get a subcurve from 2 different open polylines I encountered the following situation. I thought that the domain of a curve was constant as long as there weren’t areas of different curvature, and i thought the curvature of a polyline was zero, so trying to get a subcurve with the gh subcurve component and substracting the same number from the beginning and end of a normalized curve domain would get me the same distance trimmed in both sides. But it seems that it d…
