Problem:
2 concentric holes that need to maintain a minimum distance between their walls.
If the larger hole, which provides the reference datum, is at its maximum tolerance the smaller hole can be more off its ideal position - see large view in below image.
Which would be the correct...
Is it actually required to put a "THRU" or "THRU ALL" on a through-hole?
ASME Y14.5 (2009) specifies: "Where it is not clear that a hole goes through, the notation THRU follows a dimension."
Any other cut-out geometry is by default assumed to go all the way through a part body if no depth or...
ASME Y14.5-2009 has this for Two Coaxial Datum Features defining a Single Datum Axis:
Would it be OK to use this also with 2 sets of parallel planes like this:
Is there a way to indicate that the envelope principle should not apply when defining the thickness of a flexible part, for example a gasket made of a flexible rubber sheet?
This is how the part should be allowed to look like this when not constrained:
But on the drawing (and if installed) it...
