How to Draw Electrical Diagrams
Why care about the procedure? Because a well-planned drawing is finished faster and you avoid frustrating last-minute rework. The following steps guide you through the whole process, from a blank page to a finished drawing.
- Create a new drawing with the menu
File-Newor by clicking the icon
. - Set the drawing size — without the right dimensions the drawing won't print well. Enter them in the print settings and the page size.
- Insert a title block (if the drawing doesn't have one yet) with the key
F12-Title block. Every professional drawing should have a title block — it identifies the document and gives it a professional look. - Prepare the layers — if you need more layers, create them right away in the Layers panel. Name each layer after its purpose — your future self will thank you.
- Working over a scanned floor plan of a building? Insert it into the bottom layer as a background for drawing.
- When placing objects, start with a snap of 10 mm and refine it gradually.
Leave enough free space in the drawing — later changes will be easier. - Insert the symbols and other objects, then move them to their final positions. Leave some space at the edges — you never know which printer the drawing will be printed on.
- ⚠️ Before you start drawing wires, check that the symbols are in the right places (at least the key ones). Symbols with connected wires can later be moved only over short distances. When wired symbols are moved further, the wires may become disconnected.
-
Draw the wires. Press the
skey to switch to wire-drawing mode. Start with the longest wires that run across the whole drawing. A branch went wrong? Undo it with the backspace key⌫. End a wire in open space with the right mouse button. - Check the drawing — use the Outputs - List of wires function and verify that everything is connected correctly.
- Finally, check that texts, symbols or wires don't overlap. A readable drawing is the foundation.
💡 Pro tip: Save regularly (Ctrl+S), especially before drawing wires. If something goes wrong, simply go back to the last good version with the menu command File - Restore from archive.
