To change an element created previously, place the cursor at the element mark. Then use the change function by pressing the F14 key. The same display as the one to create the element is displayed on the image area, except that the previously entered parameters appear in their appropriate fields. The following parameters are common to all elements in this display: In addition to the parameters shown above, depending on the element type, you need to enter the mandatory parameters. By pressing the F4 key, you can also more precisely specify an element by adding more parameters. Step 6. Define the specifications. Field Name Description Mark The element mark is displayed in this field. It could be either a system-assigned mark or a user-assigned name. Measurement method This field shows the measurement method used to specify the position. You may change this field by pressing the F6 key. Position The position parameter consists of across and down values. These values specify the horizontal and vertical position of the element being defined. Possible values for each measurement method in this field are: Measurement Method Possible Value Range Inches 0 to 22.75 Centimeters 0 to 57.79 Row/Columns 1to999 Note: The possible value range depends on the size of the overlay or the page layout. If the size is smaller than the values, the overlay or page layout size is the maximum possible value. The Overlay Utility and the Print Format Utility check the specified values to make sure the element is completely contained in the overlay, the record layout, or the page layout by referring to the page size which was previously defined in the overlay specifications or the PFD specifications. If you press the F6 key to change the addressing from the current value to another, the values of this field will be changed to the appropriate values for the new unit of measure as accurately as possible by the Overlay Utility and the Print Format Utility. The element display position in the image area will be moved to the new position if you change the value in this field. Chapter 13. Design Operation 241
