Standard when Creating Mirror Image Parts...
(OP)
What is the Drawing Standard when Detailing a Mirror Image Part (such as a manifold)?
Does one need to re-dimension the mirrored part?
note: these 2 parts would be on one drawing with different Configuration Numbers.
Hopefully this makes sense...

RE: Standard when Creating Mirror Image Parts...
I have seen several methods ie:- mirrored parts on same drawing but only one dimensioned and a note that says one as shown, one opposite hand.
Individual drawings for each one both fully dimensioned which in my opinion is the best as It doesn't leave anything open to interpretation by the person producing the
component and they cannot misread and produce the wrong handed component.

We only dimension one side, usually the LH part, and note on the drawing that the RH part is an exact opposite in all respects (datums and dimensions). We only "model" one part; the other model is a mirror copy, and is completely associated to the original, so changes are only made one time.
As far as where this is determined in any official standard...?
RE: Standard when Creating Mirror Image Parts...
You have a fair point there, I suppose it comes down to how well you trust your supplier not to foul up.

Two methods described: First is that both drawings are dimensioned fully one one print. Second is basically how desertfox described.

How I build a model has a lot to do with my design intent. If my intent is that the two components are left and and right hand, I would prefer to tabulate the drawing and provide the note. If the LH, RH is something that happened and that I may or may not maintain, I would make two separate drawings.
Your point about form, fit and function is absolutely correct, and it renders much of this discussion moot.
I really appreciate how you show the left hand components, and you tell the fabricator that the right hand component is opposite. It is about time us left handed people got recognition or priority or whatever. :)
