Please show me a print with 3d TP or spherical TP. To my knowledge ( I could be wrong) I have never in my 25 years in this trade seen a callout specifically identifying such an animal.
Your interpretation may be a spherical tp. In referencing the ANSI 14.5 standard of GD & T, I can find no such animal...I am not trying to prove anyone wrong here, just I have never seen an example. Maybe I will learn something new, maybe you will....
3.3.7 Diameter and Radius Symbols. The
symbols used to indicate diameter, spherical diame-
ter, radius, spherical radius, and controlled radius are
shown in Fig. 3-8. These symbols precede the value
of a dimension or tolerance given as a diameter or
radius, as applicable. The symbol and the value are
not separated by a space.
