[LDCad] Aligning parts using rotation scripts

[Milan Vančura]

There's a single 1 to much in those lines.

Ah, such a stupid mistake of mine, thank you for pointing this out, Magnus.
I attach a new version which is, I hope, both better looking and with more readable source.

I made no changes in snap info so it still snaps to hinges types mentioned above. It works for me and expands David's script capabilities exactly in a way I looked for. I'm interested both in your experience and your tips for this helper part improvement.

For example, the naming of the "subpart" definitely does not follow any convenience simply because I do not know them, I'm not a part author. I just try my best to help But this is the last point, I believe - if there is an interest to add this part (and subpart) to standard helper parts (and when the Standard Committee agrees on them). So far, please test this and tell us tips for improvements or your experiences or that I made another stupid mistake etc.
