I've tried to fork openscad/openscad from github, BUT since I already have a fork of pythonscad (which is itself a fork of openscade), github will not allow me to create a fork of openscad to make the one line change of the setAlpha I mentioned above... If anyone can tell me how to fork openscad without deleting my fork of pythonscad, I will do a PR. Otherwise, I am stuck...

No idea why github makes it so complicated. Switching target when creating the PR is possible but I think there's no way to limit the scope once the main branch has diverged. 1) 2nd account 2) https://www.w3tutorials.net/blog/how-can-i-make-a-second-fork-of-a-github-project/ 3) make sure it's a dedicated commit so it can be cherry-picked, if that works, depends on how much of the file changed otherwise 4) clone locally only, send diff with signed-off-by (if attribution is wanted) ciao, Torsten.

Thank you, Torsten, Before I read this email, I dug around and found something that I *think* works. It is very close to the instructions you sent. Thank you for sending them. I have just posted a PR, and it is in essence a single line change. However, I added curly-brackets around the single-line if/then to follow what appears to be code style, and it ends up being three lines. Trivial change, but broke one of my projects without it.
