see attached 3dm file.
The curves look fine, but they are all degree 1 and much too many:

The only chance I see is a manual selecting, joining, degree changing, rebuilding.
As with the red egg-shaped contour.
This is very cumbersome.
Is there a smarter way?
It would help if there were a selection tool which traces such contours with respecting an angle deviation to the next element, similar to the selection chain.
