The dimensioning standard stated is BS 8888.
Datum C is a blind dowel hole, as shown in the screengrab.
After further discussions, the R5.8 isn't part of the surface profile tolerance, so will remain un-boxed. The surface profile tolerance only applies to the flats.
I agree that instead of...
Thanks for the replies
The surface profile should only apply to the flats (boxed dimension 14.01) and the 5.8 radii (shown at 12, 3, 6 and 9 o clock on the drawing view).
The 'clover shaped' slot detail in 4 positions isn't included in the surface profile requirements, so should the...
What would be the best way to tolerance/dimension or even inspect this?
The 0.002 Surface Profile tolerance is without datums, so what would it be checked to? Itself?
I had perhaps mistakenly assumed this would be checked with the datum and XY origin set to the Outside Diameter (datum A), and...
