Thanks. Another area of confusion is how to apply linear dimensions to a datum axis? Say datum axis B above now has a linear dimension to the right edge. How can I have a linear dimension or ordinate dimension to an invisible datum axis? It doesn't seem to make much sense to me.
Another question. I've seen position callouts with only a single primary datum plane, Like datum B up above in the image. Does that mean the position of the hole is not controlled relative to any translation in the X or Y direction (x-y plane coplanar with datum A)? This question assumes there...
Thank you so much Burunduk and Garland23. I figured my understanding about fixturing was correct. I'm also aware that when it comes to GD&T, design intent is critical.
Thanks for the clarification that the primary datum does not need to be perpendicular to the tolerance zone. Helpful to know...
I'm having a lot of trouble determining if the below Position callout is legitimate for or not. I've studied a lot of example positions, but there's not much literature out there for referencing datums not immediately adjacent to the position callout.
Almost all hole position callouts I've...
