This control lets you decide how and if parts that are not annotated will be included in existing packages. Choose from: Complete Existing Packages - To configure your Matching Options, first select how you would like to Complete Existing Packages.Part - Choose this to process location by Part.Designator - Choose Designator to process location by Designator.Across then up - In this mode, scanning will start at the bottom left of the schematic sheet and move left to right until all components are designated.Down then across - In this mode, scanning will start at the top left of the schematic sheet and move top to bottom until all components are designated.Up then across - In this mode, scanning will start at the bottom left of the schematic sheet and move bottom to top until all components are designated.Across then down - In this mode, scanning will start at the top left of the schematic sheet and move left to right until all components are designated.As you select one of each of the four positional annotation methods available, the graphical representation dynamically updates to illustrate how the components will be annotated. Positional annotation is directed through the Order of Processing control. Use the Tools » Annotate Schematics command which brings up the Annotate dialog OPTIONS/CONTROLS Order of Processing You can customize your annotation to package multi-part components, set Index and Suffix options, Reset Schematic Designators including any duplicate designators and Back Annotate from PCB. The Annotate dialog allows you to systematically assign designators to all or selected parts in selected sheets of your current project, ensuring designators are unique and ordered based on their position.
