The problem is, I have to support the non moving decks on the sides but my joints (I know how to do basic joints) usually release the wrong connections at least on one side. Copy + mirror + paste the working side doesnt solve this problem (I fear, the information which part of a joint will get released is not part of the construction process at all :(
I'd like to tell the program for every component that is part of a joint whether it belongs to the left or to the right part. (maybe it is useful to split a joint into more parts, imagine one part moving away to the left, one to the right and a third one is just pulled up)
Well, maybe it is just a quirk of the pre release version ;)
Fully agree with Shark there..
In the meantime, I'll try to avoid vertical elements and keep things simple - usually it splits into a left and a right separation group then.
