How to Draw Electrical Diagrams

  1. Create a new drawing with File - New or click the new file icon icon: new file.
  2. Set up your drawing size in the Print Settings and Page Size dialogs.
  3. Add a title block if you haven't already: go to F12 - Document - Title Block. See the Insert a Title Block guide for details.
  4. If your project needs multiple layers, organize them in the Layers panel. Give each layer a descriptive name based on its function or content.
  5. Want to include a scanned floor plan? Insert it into a lower layer so it stays in the background.
  6. Start placing larger objects with a snap setting of 10 mm. You can reduce this later for finer positioning.
  7. Add symbols and other objects, positioning them precisely. Leave some margin at the drawing edges to account for different printer requirements.
  8. Place all your symbols -- especially the critical ones -- before drawing wires. Moving symbols after wires are attached can break connections.
  9. Press s to enter wire-drawing mode. Draw the main wires first, spanning the length of the drawing. Press Backspace to undo the last segment, or right-click to end a wire in open space.
