OMG LOL. I didn't check this thread for a few days to come back to this.... Thanks guys lol!!!!. I'm new to eng-tips, but thanks for the entertainment.
Burunduk, Now going back to one post of yours from Sept 30 where you had a screen shot of the 2018 standard (I only have the 2009 standard) I...
Burunduk, It wouldn't work in the top view as then the trimmed edge would be 'kind of" normal to the page..as in I then would be trying to control the profile in and out of the page not left or right, up or down.
I added a top view so you can see what i mean. Maybe if I just did a detailed view...
it doesn't matter if a feature is machined or not to use it as a datum or dimension to it. the example you gave I don't see the holes toleranced to the step at all as the 28.75 is just a reference.
I would just add a tolerance to the 28.75 step to the large hole or you could add a surface...
does anyone have idea or references how to profile tolerance a complex trimmed edge on say a vac formed part? I don't really see any good examples in the standard to other places. Would it make sense to just point to the trimmed edge with a 'ALL OVER' profile tolerance with a note below that...
Thanks for all the responses.
I tried to clean up the print to clarify what i'm asking. Basically without a control/tolerance of C to datum B, sounds like datum simulator C would not stay at basic but just "translate" to touch as much of Datum Feature C as possible (parallel to eachother)
I am looking for clarification on alignments when a datum axis or center point has precedence before a datum plane or line in a DRF, especially when the plane/ line is offset to the center point or axis
According to the standards I see for 2009/2018, the plane or line datum simulator progresses...
