The Schematic Editor Window

Use the Schematic Editor window to place components and wire them together.

• Click and drag components to move them.
• Copy and Paste components and their wires within the schematic editor.
• Copy and paste to other schematics.

As you place the cursor near a pin of a component, it changes from an arrow to a large X, indicating the schematic editor is in wiring mode. In wiring mode, click to start drawing a wire, and click again to end the wire.

Place commonly used items such as ports, grounds, and page connectors in the schematic; either click their toolbar icons or use the Draw menu.

Controls to Zoom In, Zoom Out, and Fit Drawing to the editor window are available on the View menu, the toolbar, and on the shortcut menu that opens when you right-click a schematic.
