But long parts oriented along the X-axis are usually symmetric -- like
bricks and beams. Often, parts with one asymmetric axis (ie, parts with a
sense of 'front and back' or 'left and right' or even 'base and tip') are
oriented with the asymmetry laying along the Z-axis, with the 'base' or
'back' pointing toward +Z.
BTW, IMO, the Car Chassis parts oriented along the X-axis are mis-oriented.
