Common Datums

1. Unchecked Use Legacy Dimensions

2. Choose the corresponding Feature in Dimensions which should be Xact

3. Choose those datums and input # as in Pic 1

4.B(M)-D(M) should be same as  B-D (M), while A-F could type in

 [C(M)-E]. might not work.. Does it make sense for the rotation with some partial MMC?

KJAdams What feature types are being used for your datums?  2018 only supports common datums consisting of two co-axial circles or cylinders.  See:Defining Datums

this is a repeat of his previous post.

Indeed.

Did you at least read Rob's or Neil's response? Hopefully it helped you somewhat. No need for hostility here.

Hmmmmm....

(1) Coaxial Datum Feature? - PC-DMIS for CMMs - PC-DMIS - Nexus Community

Same issue? Same questions? Somehow less detailed that the first post? 
We are all friends here, sometimes all we have in common is that we were chosen to be Demon Wranglers, but at least that's something! 

Furthermore, did you ask the engineer their design intent with that datum structure? 

WE all help for free.  If we could have helped on the previous post, we would have.  But to have a fit because we don't solve the problem for you is a good way to get all the knowledgeable people to ignore your posts.
