# Status of tools in Model Close screen

If the tools that were used by the Model earlier are not issued to some other model and are in the Usable state in the Tool master, then its Status is displayed as Used in the list view.

If the tools that were used by the Model earlier are not issued to some other model and are in the Reground state in the Tool Master, then its Status is displayed as Reground in the list view.

If the tools that were used by the Model earlier are not issued to some other model and are in the Non-Usable state in the Tool Master, then its Status is displayed as Non Usable in the list view.

All tools other than the tools that were used by the Model earlier are displayed in the list view with their status as Available.

If the Status of the Tool is Used, Reground or Non Usable, then on selection of the Tool from the list view, the grid displays the values for the parameters on which the tool had operated for the Model. You can modify the value of the parameter(s), by checking the check box corresponding to the tool and then entering value in the grid for the parameter(s).

If the status of the tool is available then the Value column of the grid is empty. If you select a tool with Status as Available, then you have to enter the value for all the parameters for that tool.
