Midpoint of polylines

Note that PointAtParameter may not be the middle length

I’ve not tested lately, but a while ago I noticed that there is a difference between the API and Dynamo in this approach. While in the API each segment of a Polyline starts with a new parameter, Dynamo uses one parameter for the whole Polycurve.

Why is the parameter method in Dynamo different from the parameter method in AutoCAD

I ran into something weird. I have a polycurve in Dynamo which consists of several curves. Let’s say two elements, but the polycurve is obviously one object. I can recreate the polycurve in AutoCAD as polyline, which also consists of two elements but still is a single object. In AutoCAD (with C#) the polyline has two parameters in total. Each vertex is a parameter. So if I request a point that lies on the second element, I get a parameter between 1 and 2: [image] If I request the parameter at…
