Burunduk's latest activity

greenimi, You have to keep "LOCATION of the ENTIRE SURFACE" in its context. Which is relevant to 12-6: It centers the surface to the...

greenimi, if you insist, you could replace those total runout controls by dynamic profiles with customized datum reference frames that...

Dynamic profile releases the feature from size control, but not from location control. For example, If you apply the dynamic profile to...

Depends on how you present it on a 2D drawing. If you show a cross section perpendicular to the pipe (on a plane similar to that on...

"square" as in "presents itself as a projected rectangle or circle along its perimeter" as the OP put it. It's true that there is no...

greenimi, OP's image is a screencap from MBD. The collection of surfaces forming the entire "square" groove (bottom and sides) is...

I think it is realistic. If the OD is not too deformed and the variation in size is not too large within a batch (and it doesn't have to...

Thank you for the answer, pmarc. It is interesting and surprising, but makes a lot of sense at the same time. I think I won't be wrong...

The OP applied the profile specifically to the groove. Not sure where your concern about a general profile comes from, I don't think...

greenimi, Burunduk nailed it. Burunduk, I guess that person might or might not be right depending on the tolerance values used. In the...

There is no exact definition in ASME Y14.5 of a "refinement". An obvious refinement is: " hey, that profile of a surface limits form...

pmarc, I agree and think that your suggestion is totally valid. Each of the requirements would need to be met or the part is rejected...

Not that rubust if you consider that the face in which the hole was made and the other end of the cylindrical portion of the hole are...

That is indeed a problem. Whatever you do datum-referencing the cylinder will give you its axis as a reference.

Not a FOS, but it is considered OK to specify a directly toleranced depth.
