How to draw electrical diagrams

You can create a drawing using the File - New menu command or the icon
Select the desired size for your drawing and configure it in the Print Settings and Page Size dialogues.
Insert a title block if it hasn't been added already, using the 'Program Settings' command (F12 - Document - Title block)
If your project requires multiple layers, create and organize them in the Layers panel, naming each layer according to its specific function or content.
To incorporate a scanned floor plan into your project, insert it into a lower layer.
Begin placing larger objects with a snap setting of 10 mm, and adjust as necessary for finer placement.
Add symbols and other objects to your drawing, positioning them precisely. Ensure there is some margin at the edges of the drawing to accommodate different printer requirements.
Ensure that all symbols, especially the crucial ones, are correctly positioned before drawing connections (wires). While it is possible to move symbols with attached wires over short distances, doing so may disrupt their connections.
Use the s key to switch to the wires drawing mode and start drawing wires. Start with the major wires crossing the entire length of the drawing. If any connection was started the wrong way and you are not able to continue, you can cancel the latest diversion by pressing the backspace ⌫ key. You can end a connection in the air by pressing the right mouse button.
