Convert Polyline-contour (from pointcloudinput) to lines/arcs

Rhino Developer

Hi there,

I am trying to convert a pointcloud contur to a reasonable/useable polycurve.
This means (as shown in the picture) that I wanna join the points to a polyline.
I tried to smooth it, to fit it and to rebuild it, but it all results in an approximation.
Of course I could pick the points manually per side and fit a line though them.
I also thought of ConvertToLinesAndArcs, but the output I got was not so much different.

I am aware that this might be a quite extensive topic, but I would really like to develop this further.

Thanks,
T.

Hi @tobias.stoltmann,

You might give Point3d.SortAndCullPointList a whirl.

@dale I already am doing this before trying to smooth/fit/rebuild it.
Indeed I migth try out to increase the tolerance of Point3d.SortAndCullPointList.
