    Gap in a feature of size

    Their philosophy is rather simple: define the drawing and send it out for the quotes for multiple suppliers. Now, if we are going to ask each supplier which way they “would like to see” our drawing defined, then we will be in a never-ending cycle of permanently and constantly changing drawings...

    Gap in a feature of size

    Burunduk, So in your opinion, you would use 8x size (Ø.500±.015) and 8x position AND CF symbol? I am thinking that because of what you posted "The number of surfaces "n" that are included in the CF, such as “n SURFACES,” may be added beside the “CF” symbol." or you would NOT use 8x for...

    Gap in a feature of size

    If would be up to each supplier then we will use only plus minus. No other controls. And beside of that each supplier has its own QA and their interests and vastly opposed. I have only drawing and not 5 or more -one for each supplier- Yes, it is true. Runout is is not feasible due to the...

    Gap in a feature of size

    Will those 3 proposed solutions provide the same mathematical definition ? If not, what would be the differences between them? Is it really a good idea to ask each supplier which method they would prefer? (we are sending those parts for quotes/ be made by differnt suppliers) I might get...

    Gap in a feature of size

    I am confident that the actual function, design intent and the datum reference frame are adequately covered. The question I have, at this time, is how to define in ASME the pattern of those arcs? What would be the best / standardized method?

    Gap in a feature of size

    3DDave, Runout option has been explored before, but since this feature it is not easy accessible (nor can rotate due to other features involved) this runout option fall by the wayside. So which option would you prefer: CF + position on the phantom circle OR 8x .500±.015 + 8x position to main...

    Gap in a feature of size

    I have a faucet plastic component which has gaps/ interruptions along the circumference of an outside diameter. I cannot share the entire part, but something which is very similar is shown below. The outside diameter has 8 gaps around the 360° degrees which creates 8 arcs. How can I define those...

    How to interpret those dimensions ?

    Couple of questions: 1.) If drawing shows ASME Y14.100 only, should I understand that rule#1 is enforced? Or only if ASME Y14.5 invoked directly (shown on the face of the drawing) implies envelope principle being in charge? 2.) How to interpret what tolerances are applicable to the dimensions...

    ISO and Individually note

    ISO 16792:2021 it is for MBD, but my question is not really related with it even it is invoked in the TDP (Technical Data Package). 1. If a pattern has 5 holes and only one hole is detailed, then what is the best way to show that are actually 5 holes? 5x under the detailed view or 5x for the...

    Is it OK to have drawing with tolerances that are over the ISO standard?

    Probably instead of saying "it is Ok" you should have asked "it is clear for the reader of this drawing", otherwise stated does the drawing specify clearly and unambiguously the requirements?

    Compound datums for hole intentionally not perpendicular to surface into which it is drilled

    Is this ISO or ASME drawing? Because in ISO "A-B" (where "A" is a planar surface and "B" is a cylindrical surface) DOES make sense and it is valid. However "A" SECONDARY and "B" TERTIARY are pushing the line of absurdity.

    Movable datum target on flexible parts

    Do you think movable datum target could be used on flexible parts - subject to free state variation? Or maybe the standard's intent has always been to use it for rigid parts only? Any examples, books, training materials to support this approach.

    ISO 8015 and envelope requirements

    Looks like there is still room for (more) arguments and ISO is not crystal clear on this aspect. Does not look like I have enough support from the standards and its theory to go back to the designer to have the print corrected.

    ISO 8015 and envelope requirements

    Should I understand that this subject is not clearly defined by the ISO standards? Or offer multiple legal interpretation? What is a standard industry practice?

    ISO 8015 and envelope requirements

    3DDave, Please clarify a little your opinion: your statements (copied above) from ISO Standards is to prove or disprove cr7's stance that ISO 8015 and E combo is an invalid specification? If i read the first sentence posted above i would say that E is a portion of an ISO standard, hence ISO...

    ISO 8015 and envelope requirements

    Do you have some statements from applicable ISO standards to support your point? I am trying to show it to designer in order to get the print fixed.

    ISO 8015 and envelope requirements

    Cr7, I understand your reply, but that was not what I was asking😊 I've seen drawings with only 8015 E and I am questioning their validity in ISO GPS.

    ISO 8015 and envelope requirements

    When on an ISO drawing that has ISO 8015 already specified, the designer wants to have the envelope requirement enforced, does he need to specify also ISO 14405-1 along with circled E or just circled E is enough somewhere close to ISO 8015 already shown? So, is ISO 8015 E a valid ISO GPS...

    Profile Basic Dimensions

    Can you use multiple in between symbols one in top of the other? Then each will have its own separate features to be applied to and because of multiplier note will make a pattern.
