This isn't about the brick's file itself. It's just that I don't understand
the way LDD is placing bricks and messing up their rotation vectors in the
process to create misaligned bricks in the model file itself. I can send
you a model file if you like to show you what I mean more clearly.
It seems to have something to do with the way LDD fractionally rotates
pieces to create lineups that occur if you spin a part more than one
revolution to line it up with another part in LDD.
I went and rebuilt the assembly I was having problems with and everything
lines up properly now.
Cheers ...
