Hanging bar dimensions

The field drawings (not the team plans or rules) are the most authoritative. That said, you should not expect the field to necessarily exactly match any one of these plans.

The competition ARENA is modular and assembled, used, disassembled, and shipped many times during the competition season. It will undergo wear and tear. The ARENA is designed to withstand rigorous play and frequent shipping. Every effort is made to ensure that ARENAS are consistent from event to event. However, ARENAS are assembled in different venues by different event staff and some small variations occur. For details regarding assembly tolerances, please refer to the 2016 ARENA Layout and Marking Drawing. Successful Teams will design ROBOTS that are insensitive to these variations.

It is not uncommon for the differences between the field drawings and the actual fields to significantly exceed the field drawing tolerances. In Ultimate Ascent, the frisbee feeders were about an inch and a half too low, and the first rung of the pyramid rather high (we weren't sensitive to that one, so I don't know by how much). Design so that the errors don't matter, or at least so that you can make adjustments at the event. IIRC, there is an opportunity to measure critical field dimensions on the first day of each event. If this matters, take advantage of it. Here it is, between rules T26 and T26A:

5.5.8 Measurement
The ARENA will be open for at least 30 minutes prior to the start of Qualification MATCHES, during which time Teams may survey and/or measure the FIELD, and bring ROBOTS on the FIELD to perform sensor calibration. During this time ROBOTS can be enabled, but can not move, nor can they interact (e.g. shoot, push, pickup, etc.) with BOULDERS or DEFENSES. The specific time that the FIELD is open will be communicated to Teams at the event. Teams may bring specific questions or comments to the FTA.
