doubt symmetrical object listing

Zamparto

Bye to all,

I have a doubt about the quotation of a symmetric object compared to a plan. In my case (enclosed image), I have four holes, symmetrical to two, and two "relays", also symmetric. can I quote only the holes and the rise that are on the left and give for """"""""" the quotas of those that are on the right, since the symmetry line is present, or is it necessary to quote everything?

thanks to allDisegno.webp
 
first you must specify that it is a symmetry axis by putting l'indicazione cl; then or quoti regarding the symmetry axis, therefore not from the outer edge or repeat the quotas, but this depends on the function of the object.
quota 65 makes little sense because it is a result, therefore it would eventually go in parentheses, and therefore does not allow construction
lacks the height of both the plate and the lifts.
missing hole size
 
the distances of the holes I would have no doubt to replicate them, as well as the width of the rise (30 seconds more? Maybe less...). then I would only quote a hole with the note "nr. 2+2 holes". less "interpretations" let and the better it is.
 
So duplicating the odds I also have to duplicate geometric tolerances and roughness, right?

not necessarily.
you must always start from what is the functional quotation. tolerances must be put where they serve and consequently roughness.
you could also quote interaxes compared to cl 617 and 517 by inserting tolerances on those odds
or tolerate only 50 and not 40 which may not be important and therefore remain with general tolerances
if you do not know what is the function of the particular you make a generalist quotation to pleasure provided it is complete
