Question Regarding True Position

[[Ra...]]

Call out No.34

Can i make a symmetry and a symmetry plane from the design as shown. Taking Two planes on left side and Two planes on Right side and creating symmetry plane and a symmetry. Call out a true position and use one of those as datum's and other as the feature.

or would there be a better way of doing this ?

Thank you guys.

Yes you can, but if you are indebted to standards you have to check whether it is ISO or ASME..

ISO.

Yes, what you could do is take the symmetry planes of the planes on the left, and do the same for the planes on the right. After doing so, you can create a plane and recall the 2 symmetry planes. After doing that, you can do what you have to in order to get the true position.

This will also work with symmetry points. If you do it with points, it will take the midpoint of the 2 symmetry points and pull the true position for that.

Did I explain it wrong? I know am almost positive I have done this in the past.

Even though both ends are the same thickness, they do not appear to be the same feature. So, to me, it is position of the symmetry plane on the right to the symmetry plane (Datum A )on the left.

Oh wow. I didn't even realize that. Guess it really was a long day for me yesterday 🤣 thanks for clarifying though.
