I have a related question if nobody minds. One way I *would* like to relate the different sides of the plate is to have the position of dowel hole datums closely tied together in the degree of freedom they control, the x-direction. However I do not want a super tight y-direction tolerance and I...

Thanks pmarc, that makes sense, I can see how the linear dimension is ambiguous. Is defining the bottom surface, one side, and the back surface as datums the best thing to do? Those surfaces are not particularly functional. From a function perspective wouldn't it make more sense to define the...

Thanks for all the input everyone, especially 3DDave. Good to know I wasn't totally barking up the wrong tree with my approach. I had just never seen a drawing with so many datums before. I guess most examples in standards and training are kept minimalist. To try to clarify design intent, The...
