I see some drawings show gd&t without basic dimensions given. There is a little block onnthe drawing, says “basic dimensions are from CAD..”
My questions/concerns:
Most the time I’ve heard “drawings are amaster” so If now you rely on CAD.
The question: are all cad software reads/shows...
Hi,
I just make up a sketch which is similar to a drawing we got from a customer. Would anyone see which sketch would behave practical callout. sketch A or A Mod?
Thanks!

Please see an attached picture and can someone tell which one is a better callout?
The old one: How is the 45° angle line inspected?
The purpose of the drawing is to control the pocket width and its 45° edge...
Hi All,
Please see attached picture and help me out....
1/ Will 2 Radii need to be inspected for size? If yes what is a tolerance, +/-.002?
2/ What does True Position call for
(a) Mid point of slot width and center of 2 radii?
(b) Mid point of slot width or center of 2 radii?
(c)...
Hi All,
I guess this is an old question but I still see drawings here and there showed NO LOCKING DATUM FEATURE.
Please see attached picture which is from ASME Y14.5-2009, page 121. The basic 8x 45deg is from vertical line to center of |B| and center of a hole.
For calculating the TP, we need to...
Hi All,
I see this callout on a part I'm checking. I've not seen the way it called out for concentricity like this. Does it mean center of 3 .250"Holes (Boldcircle) concentric to |B|?
(Normally, I see concentricity of 2 circles at the same locations.)
Thanks...
Hi,
I have another question regarding Tertiary Datum Feature again.
Sometimes, I see a drawing having 2 pins. Most of drawings pointing at one(1) Pin with label |C| and other pin will have True Position...
(Please see attached drawing).
My questions are:
1/ If a design is used one(1) pin for its...
There is a hole labeled as 3rd datum |C| feature located in 1st quadrant @60degree from X axis.
The question is: does it matter if you rotate to align with Y instead of X axis for inspecting? Like if you rotate to align Y axis then it's 30deg. or 60deg to the X...
