True Radius

True Radius

True Radius

When dimensioning multiple radii of the same size, how should it appear?



RE: True Radius

Yep, there it is on page 70. I don't know why it wasn't on page 14 where True Radius is defined.

Anyway, thank you. You rock!

RE: True Radius - "...TRUE is added before the radius dimension."

I would read that to mean that "2X TRUE R" is the correct method. The example pmarc cited follows this convention.

RE: True Radius

pmarc and All,

What would the meaning in Fig. 4-28 be if it didn't say TRUE and just had 12X dia. 7.0 7.1 ?

RE: True Radius

Without 'true' in Fig 4-28 one would assume that the holes were nominally normal to the view plane; their axes would be parallel to each other.

RE: True Radius


Leaving off "TRUE" would imply that all the holes are perpendicular to the drawing view projection plane.
