Parallel constraint flips part
Parallel constraint flips part
(OP)
I'm pretty clueless here.
I opened an old assembly and for an unknown reason one of the parallel constraints had flipped on of my parts around (either part was fully constrained, but both positions of the parallel constraint are viable within the given constraints).
Thinking of the fast way to solve this problem, I simply deleted the constrained, flipped the part via the move command and added a new parallel constraint.
Everything seemed fine until I pressed OK, and saw the part flip again.
Any ideas?
P.S.: is there a reason there is no 'alternate solution' for the parallel constraint, or has there just not been enough demand for it to be implemented?

Thanks John, for spending your valuable time to answer my stupid questions.

RE: Parallel constraint flips part
I have an assembly with several arrangements where a part is constraint with an angle dimensions going from 10-90 in steps of 10 degrees.
Now, if I go from one arrangement to the other every single one of the angle constraints has flipped (just like the parallel one from above). So, I thought I'd head to the angle dimension, rightclick, "edit in arrangement" and change them all for +x to -x since that would flip them properly.
Having done this, the arrangement that was open flipped back to how it should be, but, when I went to the other arrangements, they were still wrong, and moving them back to +x (one at a time) made them right again.
As you see I was able to fix the problem, but I'm pretty sure that's not how it's supposed to be working.
Or am I doing something wrong?
