• In Gimp these are paths, they are saved with the image (if you save as XCF), and remain editable. If you want to adjust something, you just drag an anchor.
  
• The whole point of my Path-to-Shape series is no never have to enter coordinates. The coordinates are taken from the path on which you call the function.
  
• You can write a script to rebuild your construction using the ofn-path-to-shape functions but you will likely have to set each line to its path.
  
• Furthermore ofn-path-to-shape functions are not designed to be called from scripts. They will work but you can have ambiguities about the result path, etc...
  
• Once you have removed the relative complexity of Bézier splines, these function are fairly basic applications of Cartesian geometry, so you can achieve the same result directly in a tailored script.
  
• Keep in mind that circles can only be approximated by Bézier splines, distance from any point of the "circle" to the center can vary by about .5%.
  

PS: What is "Brun"? The only number I can relate this to is "Brun's constant" but the existence of this number was established in 1915...
