01- I reproduced the steps presented by denzjos in post #18;  ( With this I created 3 paths: Top, Bottom and guides vectors )

02- I duplicated the paths (Top and Bottom);
03- This left me with 4 paths - Top, Bottom, Top copy, Bottom copy and Guides vectors;
04 - I applied the Replicate path by affine mapping plugin, between the paths: Top and Top copy, generating the Top replicate path;
05- I applied the Repliacte path by affine mapping plugin between the Bottom and Bottom copy paths, thus creating the Bottom replicate path.
06- Finally, I applied the script provided by rich2005 - Distortion Correction Between Paths  (on the Top repliaction and Bottom repliation paths) ... and voilà

This way it was possible to follow the steps given by denzjos and get the script working correctly.

Krikor, thanks for the tip. I can replicate your workflow, but the 'Distortion Correction Between Paths'  result in an error. Can you make a screenshot (and post it) from the setting in the 'Replicate path by affine mapping' you used? Thanks in advance.

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.
