section in multiple locations

section in multiple locations

section in multiple locations

(OP)
I have an assembly that has 3 instances in different locations that are a common configuration. In some cases, just saying "3X" under section view would work, as long as it's obvious where the 3 instances are. What about when it's not so obvious? I don't think you can apply 3 cutting plane lines with the same letters, can you? Or do I draw a cutting plane line at each location, apply different letters, and at the section view state (e.g.), SECTION A-A, SECTION B-B, SECTION C-C?

I looked at Y14.3, but it neither spoke to this nor prohibited it. So, I guess you're saying it's OK to have multiple cutting plane lines with the same letters?

RE: section in multiple locations

I think it is less confusing then having one single section view with several titles like "SECTION A-A, SECTION B-B, SECTION C-C"

I believe similar suggestion was already made for having several identical detail views before: http://www.eng-tips.com/viewthread.cfm?qid=372706

RE: section in multiple locations

I always thought section lines with letters 'A' are actually saying 'SEE SECTION A-A' smile

I think what KENAT means is to add a leader note to the other two areas. Only reason this is an issue at all is it's not blatantly obvious where all three instances are.

Exactly. So identifying Section A-A as "Section A-A" is less ambiguous.

You could add number of places to the section view, so person working with the drawing will know what to look for:

"Section A-A, 3 Places -- That means I have to look for 3 places that have section lines and letters "A"

I can live with having 3 cutting plane lines with the same letters, as long as Y14.3 is not being violated.

RE: section in multiple locations

Are all 3 locations truely identical in every respect, or just some design detail is identical in all 3 locations?

I.e. would all 3 sections look exactly the same, or they'd look different but the detail you want to dimension is the same?

Unless they are truely identical in every aspect I'd be very wary about repeating the cutting planes. Maybe if you then crop the subsequent cross section view to only show the detail of interest might still be OK but still could be a bit confusing.

RE: section in multiple locations

They are in fact identical.

RE: section in multiple locations

Thanks for all the input. I think I'll go ahead and do what I mentioned, since it doesn't complicate the drawing, and to the assembler, it should be clear that this section detail is applied in the 3 places indicated. If someone has trouble with it in the checking process, will have to go to plan B.
