I think there are two kinds of fixtures we could be talking about here:

1) A fixture designed for a specific part. It is not useful for any other part. e.g. a plate used for locating cuts on tubing for an arm used in the 2014 game.

2) A fixture used for making repeated feature spanning multiple robots. It can be used in a variety of ways. e.g. a block with a locating pin and drill bushings to drill a straight pattern of 1/4" holes 1" apart.

Type 1 is VERY closely related to CAD drawings and designs in general. I wouldn't push that limit if I were you. Type 2 I think is fully in keeping with the rules.

Note: If you're not sure about it, post the design on CD, and then you can use it during the build season because it has been made equally available to all teams.
