Question Regarding True Position

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, 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.

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.
