Typical opposite end callout
Typical opposite end callout
(OP)
Hi,
Just for a refresher I wanted to ask the correct way to callout Typical opposite end in a drawing. In this case a very simple one I have a round bar with the same chamfer on each end. I could make a detail of one end and have it say 2X Detail-A or make two details.
What's everyone thoughts.
Thank you,
Jeff

If however the part contaied more than just two chamfers (e.g. in a multiple stepped shaft), I would probably dimension each of the ends separately. Not so much work, lot of clarity added.

Just stay away from TYP
RE: Typical opposite end callout
I have called out chamfers many different ways. Just wondering; why not use TYP?

It has been replaced in the following standards: 1973 specified 4 HOLES, 4 PLACES OR 4 HOLES EQ SP, and in 1982 / 1994 replaced again by using a number followed by an “X”, as in 4X for 4 places. HOLES EQ SP (equally spaced) are no longer used as well.
If there are numerous elements not worth counting, standard recommends to create a general note such as “UNLESS OTHERWISE STATED, ALL NTERNAL RADII ARE 5mm.”
So did I. I also used to put “NUTS AND BOLTS AS NEEDED” in the BOM and dimension certain holes to the edge instead of center because it was “company standard”. But I come to this forum to learn and discuss correct standard-compliant ways to do things, so here you go: I share my knowledge about "typical"
RE: Typical opposite end callout
you are right, it has been company standard.
Now, I am in a position to change the standards; so a good argument is nice to have. I have been going through ANSI standards in order to Implement new standards. Just saying "Because that's ANSI.", hasn't been as effective as I thought.
I need to change habit not just documents.
Thank you.
