Ofnuts,
I understood what you explained.
Deep down, we laymen always think that you plugin/script wizards can do magic and create any kind of thing.

denzjos,
By chance I still had this case open in my Gimp. So I saved it as .XCF and will leave it attached.

There are some small differences, the names of the paths are different, since in the forum here I used names to better exemplify the steps I used.
Here's the screenshot - I opened the plugin and these are the sets I must have used last, as I don't remember using this plugin after describing the steps in my last post.

Krikor , thanks for the information but I can't get the handles from the the nodes symmetric. In your example the path layer 'top|chop' and 'top|chop copy' have a handle that point to the left direction. The path layer 'Path Top' have symmetric handles on the nodes. I can not reproduce this with the 'Replicate path by affine mapping'. After using the plugin the handles still pointing to the left and are not symmetric.

To make handles symmetric just drag one of them with the Shift key pressed.
