This recipe is part of my typical design-toolbox.
hxb stands for "helix bander". There are already some recipes out there that do this but I wanted to keep it as simple as possible.
This recipe should be used on helix only. It will add bands to n+3 and n+4 segment.
To use this, select the consecutive segment-range of the helix that you want to add these bands on. Then run this recipe and the bands will be created over all the selected helix-range. Attention: If you have not selected anything before running this recipe then bands will be applied to all non-locked segements which could be a mess :).
That's it. This has been quite helpful for me especially with linker-puzzles and when a helix has deformed.

Happy folding to all!
