Can you help me with this?
What is the perpendicular call out actually doing with the outside surfaces if its not actually giving me perpendicularity to a surface?
What is the difference between perp being on the FoS as in Fig 10-59 vs having one side be a datum with a flatness and the otherside...
I think that clears some things up in my head for me.
Can i have the width be a datum(in this case -C-) and also each surface be their own datum?
so the width be C
the left surface be D
and the right surface be E?
I can set D to be perp to B and A
I can set E to be parallel to D
So Datum C...
i saw that post when doing my searching and it really got me thinking(and confused).
in this case. the overall width can be +/- .01. So the overall rectangle can be a parallelogram with .01 to the top left of the part and .01 to the bottom right of the part. I would rather keep the overall...
I have a big weldment. All sides are to be machined and held flat ~.01"(still working that out). From one long end to the other i was going to hold that dimension as a datum and then hold the rectangular hole pattern to that dimension. Doing it this way i can keep the hole pattern 'symmetric'...
