Rules for Using Check Out
Consider these rules when using Check Out:
By default, when you check out a generic CATIA V5 CAD document, all instances are also checked out.
You can make changes to the attributes in Windchill without checking out individual CAD document.
When you check out a generic, the design table and the CATIA V5 model file are added to the workspace as the primary content.
When you check out a design table, all instances such as generic part, design table, and instance part are checked out into the workspace.
