Thanks for all the help. After going back and reviewing the units amongst my files and getting everything positioned properly it is now working!

One small stumbling block, I was initially using a negative value to scale in xform instead of a decimal (-2 vs .5) which obviously doesn’t work. Apparently I got used to using the negative value with the AIM, PIVOT, etc in rvu, and transferred that to xform!
