The Filter Only button is used to process a selected operation to create a new operation. Click an operation in the Operations Tree and a filter from the Filter List box. Then click the Filter Only button. If the filter has an associated dialog box, it will then be displayed for you to enter the values for applicable parameters. After you click OK, SURFCAM will display the Keep Operation dialog box.
Click Accept and an icon for the new "filtered" operation will be added as the last one in the current Setup Section. It will have the same name as the "unfiltered" operation you previously clicked. You may then decide which of these two operations you wish to keep.
