Navigation:  Model Geometry > Editing Model Geometry > Move

Modify > Move acts on selected nodes and allows them and their connected members, shells and bricks to be moved by the specified X, Y, and Z distances.

 

It has an option to allow nodes and elements to be merged.  When the option is selected to Merge nodes and elements, if a copied node, member, or shell falls exactly on top of another node, member, or shell, the program will automatically eliminate the duplicate to avoid problems with model geometry.
