Deleting an IF_Block removes all uses of the IF_Block from the reservoir's operation sets, even if the IF_Block is nested inside another IF_Block. After removing all reference to the IF_Block in the operation sets, the IF_Block is then deleted from the reservoir. Since Delete is such an encompassing operation, it is only available from the IF_Block menu.
To delete an IF_Block:
Select an IF_Block in the *Zone-Rules* tree. [Any IF_Block will do in order to activate the *Delete* option in the IF_Block menu.]
Select the IF_Block you want to delete from the list of existing IF_Blocks and click OK.
A Delete IF_Block confirm dialog will open ("Figure: Delete IF_Block Confirm Dialog"). Click Yes to complete the delete process. No will abort the delete process.
