Thanks greenimi.
I have not come across that notation before. Usually always see |A|B|C| vs |A-B|C|. I understand you are saying the difference is defining A & B datums as both primary in the latter. Is this commonly used?
Here is the updated Section B-B that should capture what you are...
No, there isn't right now. I will adjust several tolerances later due to wear on existing mating components, etc. Still getting field dimensions on those so a few tolerance values are placeholders for now.
As for ISO, originally that is likely - I work with a lot of drawings that are German...
Thank you greenimi, Burunduk, drawoh for the responses.
Figured it would be easier for me to draw the changes and provide them for critique of my understanding of how to effectively replace these.
I used runout and removed the concentricity, and have attempted replacement of the symmetry with...
Understood on this, thanks.
How would that look to achieve the same results as symmetry? This is where I am struggling.
ASME.
Lets see if this is better.
I am working with some legacy prints that make use of symmetry and concentricity. Looking for advice on alternative tolerance options that can replace these. I am fairly green to certain areas of GD&T and would appreciate some input.
Parts are mainly rotating steel shafts. Print below...
