View Full Version : OTP CIRC - Old drawing (1968) that calls out a dimension within .005" OTP CIRC Jonell 20th July 2007, 04:03 PM We have an old drawing (1968) that calls out a dimension within .005" OTP CIRC, and another dimension within .004" OTP. We're thinking that this is some kind of true positioning callout, but aren't sure. Has anybody else ever seen this before? Thanks!

Jonell My guess is that it probably means "within .004 Of True Position," but it's only a guess. Best to ask whomever the drawing belongs to. |
