I describe what I tried to do: After I drew a path curve through some points and made some other modifications to that curve I decided to change one single point of the curve. See image:
- old point on the curve: Rm1 (point at distance along line, dotted horizontal)
- new point: A4 (point at distance along line, dotted vertical)
As you can see on the picture, I cannot exchange "Rm1" with "A4" and I don't really understand why. Could it be because "A4" (internal point id 97) has been created after "Rm1" (internal point id 63) and also after connecting the points to form the curve?
BTW, I was indeed able to achieve what I want with a more complex manual edit of the .val file with the help of Notepad++ ;-) but inside Valentina it would have been so much easier...
