Hello!
It would be extremely helpful for me to constrain the length of also a line and an arc in the sketcher. So I could generate (rather trivial) sheet metal unroll jobs in the sketcher.
Thank you!

I am not absolutely sure, but I think that my request is similar, but much more trivial, as I was asking for the length of a simple arc (given e.g. center, starting and end-point geometry, radius) to constrain. Compared to splines or other complex curved geometry as it is discussed in your post, the algorithm of constraining the length of an arc to another length might be considerably simpler. And for me: very useful
