Saving your drawing using Pack & Go creates a new file that contains both your drawing and your CAD files referenced in your drawing. This makes it easier to work on the go without access to local networks or for sharing with colleagues.
To save files as a Pack & Go package, follow these steps:
Select the Create Pack & Go package from the File menu.
CET Designer prompts you to save your drawing. Click Yes. The Pack & Go dialog opens.
CET Designer suggests
a location for the saved file. To change the location, click the 
button
and select a new location. When you are satisfied, click the Pack & Go button.
To open a Pack & Go file, follow these steps:
Select Open from the File menu. The Load Drawing dialog opens.
Locate the requested file and click the Open button.
