Rules for Using Undo Checkout
Consider these rules when using the Undo Checkout action:
By default, all members of the design table are selected when you perform an Undo Checkout action. You cannot exclude any member from the selection.
When you perform an undo checkout action, CAD documents created for the new instances are removed from the workspace.
Undo checkout can cause new files (for a generic, that includes a design table and instances) to be downloaded. You may be prompted to replace the model in session. If this occurs, all members of the design table must be replaced or none of them.
