If you don't use Autodesk® Vault® or Gain Collaboration or any similar programs then this tool might help you to manage your documents.

Many Autodesk® Inventor® users (like me) have the problem with copying inventor files Parts and Assemblies (.ipt & .iam) and its drawings (.idw or .dwg).

Copy Assistant Will help you overcome this Problem. The program is set by default to copy the active document, but the user can select another Document to be copied.
Only one document can be copied after clicking the app icon.

To get the best use of the program, please make sure that the drawing document is in the same folder as the Reference document (.ipt or .iam)

If you are using .dwg or .idw format files for your drawings, don't worry the App can copy it too!

It also helps you when replacing a component in an Assembly.
