symmetry in a drawing
symmetry in a drawing
(OP)
hi everyone,
i have a question about symmetry in drawings , what is the correct way to indicate symmetry on a drawing in such a way that i wont have to write the dimensions of features that are in the middle of the symmetric part , its a little hard to explain in writing so i have an example in the attached photo , what i want is not to use the dimensions 25 and 40 that specify the distance to the center of the hole but rather that this dimensions will be implicit from the symmetry of the part.
thanks.

2) In your case I'd probably have done something like Checker Hater depending on function etc. Here is his illustration imbedded.

Also the OP says "what i want is not to use the dimensions 25 and 40 that specify the distance to the center of the hole but rather that this dimensions will be implicit from the symmetry of the part"
