problem with translation
 

Hi!
I have a file X_T( parasolid) to define my blade. The trouble is that it is located too close from r=0. As a consequence, the curve of the hub cuts r=0.
So, I have to make a translation.
I translate the hub, the shroud and the blade. When I try to link the blade which has been translated, it didn't match with the hub and the shroud in the meridional view.
I don' understand because I apply the same translation to the blade , the shroud and the hub.
any idea?

use the "bulb" Button，and use the bulb function
