Re: centreline between 2 polylines
so the Output looked good at first glance, but upon closer inspection it's obvious that this doesn't work accurately (at least not for my curved Situation)
Here the red line (Output) doesn't cross through the midpoint of the selected line, and for the curved part of the Output, lies obviously Closer to the top black curve. Why is this?

Why not? Why did you draw the selected line in the position which is shown in your pic? How is the position of your line determined? My attached pic shows as example three other lines, whose midpoint is placed at the "centerline" and the endpoints touch the two borderlines.
In other forums we have discussed this issue (create a middle curve between two given curves) very often - without a finally result. The main problem (IMHO): nowone can describe exactly, what is the middle between two curves.

For some discussion of that issue, see >this< and following Messages on that same thread, especially the link at the end of Message 44.
Thx to @Kent1Cooper for the link.
Here still another way to get a centerline between two given curves (2D).
In many (not all) cases we get an acceptable solution.
(I didn't a close check if this way was already shown in one of the previous postings).
