DRAWING NOTES

DRAWING NOTES

(OP)
"SOME COMPONENTS NOT SHOWN FOR CLARITY" placed as a drawing note sounds like you are showing components for some other reason besides clarity. Wouldn't it be more correct to say "SOME COMPONENTS NOT SHOWN" or to say which exact components are not shown? I have seen this note under a view where some components have been removed. Instead of being declarative, we are giving unnecessary reasons for why we created a view missing some components.

RE: DRAWING NOTES

Or,
"The parts you do not see were not drawn"

Sometimes its possible to do all the right things and still get bad results

RE: DRAWING NOTES

I typically specify WHICH parts are not shown. I prefer specificity. Not specifying which components are hidden leaves the viewer/reader to assume that the part they can't find is not shown, rather than it possibly being overlooked, but present. It can also mean you avoid the incorrect assumption that "this part is P/N 004" when you have a note saying "Part 004 not shown" then they know it's something else.

I keep the "for clarity" phrase out of habit but I suppose it is a useless.

RE: DRAWING NOTES

"SOME COMPONENTS NOT SHOWN FOR CLARITY" means that inclusion of those components on the drawing would make it difficult for the viewer to see certain things that are required to be seen in that drawing. For example, removing the hood from a car drawing would add clarity to the engine compartment view, so "Hood not shown for clarity" makes perfect sense.

RE: DRAWING NOTES

really???

RE: DRAWING NOTES

"Item X not shown for simplicity" or "Item X not shown for ease of drawing" or whatever applies. Don't say "for clarity" if it's because you just didn't want to draw it.

RE: DRAWING NOTES

Hi Dallas2000,

Got an example (for clarity bigsmile ?

RE: DRAWING NOTES

"SOME COMPONENTS NOT SHOWN FOR CLARITY" means "SOME COMPONENTS ARE NOT SHOWN SO THAT YOU WILL MORE CLEARLY UNDERSTAND THE ONES THAT ARE SHOWN" but that is so much longer. :)

RE: DRAWING NOTES

(OP)
I understand what the note means. I just don't think it's necessary to say "...FOR CLARITY". The whole drawing is "FOR CLARITY". Also, it's like saying "ITEM 4 ADDED TO HOLD COVER IN PLACE" I don't need to say why I did something on the drawing. I just need to inform the reader that this is what was done regardless of my reason.

RE: DRAWING NOTES

If you don't think it's necessary - don't write it.

RE: DRAWING NOTES

I agree that the "components" should be specified. As in "HANDRAILS NOT SHOWN FOR CLARITY" OR "HANDRAILS NOT SHOWN". Just stating "SOME COMPONENTS" is a poor practice to me as there are numerous things that could not be shown and it is up to the reader (novice or senior) to interpret everything on the drawing that may not be shown. Stating what is not shown solves that issue and allows the reader to continue with their work rather than having to analyze everything to find out what all is not shown. As far as the "FOR CLARITY" comment, it doesn't matter to me. Put what you want. An argument over whether or not to put 2 extra words is not worth it to me.

RE: DRAWING NOTES

I only use this form of note on assembly drawings, usually exploded views. I call out "ITEMS 3, 5, 8 NOT SHOWN" as needed.

I also believe specifying exactly which items are not shown in a view is the best practice. I am trying to convince my manager that is the best way to go.

Bear in mind that this will create an easily overlooked list of items that will need to be maintained throughout the drawing revision process. When part "456XYZ" replaces "123ABC" are you going to remember to update the assembly where it isn't shown (and the CAD file may not even reference it)?

RE: DRAWING NOTES

Assuming there is a BOM on the drawing perhaps use the statement as a flag note and indicate each part by placing it next to the corresponding entry in the BOM. That way you can keep the note succinct but still indicate which parts are not shown.

I like this idea.

RE: DRAWING NOTES

So I normally say 'ITEMS X, Y AND Z NOT SHOWN FOR CLARITY' - not sure I can explicitly justify the use of 'FOR CLARITY' and generally I'm all for 'less is more' on drawing annotation but not sure this hits my threshold.

Can't imagine ever having a day at work where this was a worthy topic of conversation with my manager though - you hiring Dallas.smile

This comment, for clarity, is a lie.

RE: DRAWING NOTES

[deleted for clarity].

RE: DRAWING NOTES

I agree with adding "ITEMS X, Y AND Z NOT SHOWN" as this succinctly describes the view in question; "for clarity" adds little to nothing as far as drawing interpretation. The reader needs to know what more than they need to know why.

RE: DRAWING NOTES

sometimes I show objects in an exploded arrangement, for clarity and say so

RE: DRAWING NOTES

This thread is great.

RE: DRAWING NOTES

If the components are not shown in a view they're obviously not important so why would you want to list out every missing nut, washer, and other component not relevant to that view? In many assembly views that would entail listing dozens of parts and potentially confuse others with unnecessary info. Simple is best when it comes to prints IMHO, if it doesnt need to be on a print for manufacturing or assembly then leave it out.

RE: DRAWING NOTES

FOR CLARITY, SOME COMPONENTS NOT SHOWN




There... rearranged a few words and added a comma. Confusion avoided.

RE: DRAWING NOTES

Surely, you have heard of Clarity... glasses

RE: DRAWING NOTES

Some parts not shown for clarity and other parts shown for confusion. All parts explicitly shown are mandatory if you can find them, and optional if you cannot.

RE: DRAWING NOTES

Never heard of her. And don't call me Shirley.

I specify the components not shown, but don't specify why I was too lazy to draw them.

RE: DRAWING NOTES

Additional views and sections not provided, for clarity.
