How do I use the basic [4.39] with total run-out or do I somehow add it with the concentricity? I am lost with how to measure the 4.39". I can do it with a true position but that is not an option here.
Datum A is the inside diameter if you see the extended lines on the left inner top and bottom just a poor drawing .The groove can be dimensioned for total runout to datum A. Measure the inside diameter datum A as a cylinder then level and origin to it and then measure the grieve and dimension the total runout of it to Datum A The basic dimension has nothing to do with it thought but yes a basic dimension can have to do with a profile and or a true position callout but it has nothing to do with either callout here ..Not the Total runout nor the Concentricity callout....The basic dimension is for the other axis of the groove which must be controlled with a different feature control frame...
