Part measurement with reinstallation

Hello everyone!
Could you help me please?
I have a part with bases which i need to measured for coordinate system. But i need measured elements on the other side.
I read in pc dmis help that need measured elements, to do best fit, then turn over the part, measured another elements for to do best fit 2 and then equate coordinate systems, but CAD model don't transformation.
How can i solve this?
P. S. Sorry for my english.
