Comment 3 for bug 1509246

..and even more comments.
Non-45-degree editing has serious issues.
I have finally placed and wired (0.25mm=10mil width) a 0.5mm pitch FPC connector at 33 degree angle.
I don't know how DRC distance checking works, but it reports all pads too close. If I Ctrl-M rotate the whole board by 33 degrees, bevelled connector (reaching normal orthogonal position by that) will be error-free, and other components will fail.
The best practice seems to be rotating whole board to move the non-straight components into orthogonal position, place connecting tracks, rotate back and continue tracks.
