Perpendicularity tolerance as refinment of Concentricity tolernce 2

[waqasmalik]

Is perpendicularity tolerance is a refinement of concentricity and symmetry tolerance?
To me, perpendicularity tolerance is a refinement of position tolerance, run out and profile of surface.

And if that's the case, then DR CADD must have been a man before his time! Back then you see, we didn't even know what the term CAD meant!

But he did actually show me how to use CAD. That was - drawing a line, and a circle successfully, on an IBM 8086 Personal Computer, and actually running one of the first versions of AutoCad.

Quaint! Isn't it?
