Is there a single box dimension callout?

oddam
Hi everyone,
I have a question for you, an engineer said measurement software should give a single reading if the FCF does not have a Ø in front of the tolerance. When I see a FCF that has no diametrical symbol I report it as a + / - in the two axes. When I see the diametrical symbol, I report it as TP, giving a singular reading. My question is, is there a way to report a single reading for a box dimension callout? I have never heard of a single reading for a box dimension, but maybe there is. I prefer to use legacy dimensioning and I am using pcdmis 2022.1.

Thanks,
Odda

  • The measured value for a geometric tolerance should always be a single value. The single measured value can be derived from one, two, or three directional values and is dictated by the symbol (or lack thereof) preceding the size of the tolerance zone. No symbol implies a planar tolerance zone, a case in which the measured value is derived from a single directional value. A diameter symbol implies a diametrical tolerance zone, a case in which the measured value is derived from two directional values. A diameter symbol preceded by the letter "S" implies a spherical tolerance zone, a case in which the measured value is derived from three directional values.
