Fixator rings are circular rings of metal or carbon-reinforced plastic, typically with two circular rows of uniformly spaced holes where struts and other fixings may be attached. The number of holes is usually divisible by 6, and the holes in the 2 rows usually coincide radially every 60 degrees.
Define ring parameters here, with a ring identifier for use when defining fixator frame parameters. The identifier can be a manufacturer's part number or other string. Permitted characters are letters (A-Za-z), digits (0-9), hyphen (-) and underscore (_).
If you enter an existing ring identifier, and do not enter any ring parameters, then the parameters for the selected ring will be displayed for inspection or editing.
