Basic dimension question
Basic dimension question
(OP)
Hi All:
A simple question of basic dimension, when we calculate the position we need to measure the actual dimension 2X .185 as shown on the attached print, it's a true position of the feature (although I know there is a basic angle 2X 50°), shall we change it to basic dimension?
Thanks for your inputs

RE: Basic dimension question
My proposal would be to switch .185 to basic, show 2 of them on both sides of the part and apply two separate profile of surface callouts to both flat surfaces.

The print is per ASME standard, I agree surface profile control is better than position.

2) If you intend to locate the centerplane the dimension should relfect that intent (bad form).

Didn't you post this sketch or similar some time ago here and the same question was already answered?
