Can I use the drawing for a real project?

As a starting point for layout and layers, yes. The ratings, settings and cable sizes are made up, so the diagram has to be checked and changed for your project before it is used for design or construction.

Why are the layers coloured?

Colours and line weights follow the layers: power circuits are red and heavy, control is cyan, signal is green. The plot style table in the ZIP prints everything black and keeps the line weights, so you can plot in black and white as well.

Which CAD programs open it?

The drawing and the template are in AutoCAD 2018 format, which AutoCAD 2018 and later open, and so do other CAD programs that read this format. The browser viewer needs nothing installed.

A sliding gate operator, from the breaker to the warning lamp, in one drawing

Reversing contactors with a mechanical interlock, overload relay and brake motor, then the control circuit: emergency stop, open and close rungs with hold-in and interlock contacts, limit switches, photocell, key switch with an on-delay relay for auto-close, flashing lamp, hour meter and brake coil. All from the Pro palette.

Free to use and modify in your own projects, including commercial ones. The ZIP holds the sample drawing, a template, a plot style table and a README; no add-in needed. The data in the drawing is made up, so it is not for design or construction. Provided as is, without warranty. Library terms (CXL-1.0)

The template

The electrical template has 16 layers with colours, line weights and linetypes (power circuits, busbars, control, signal, protective earth, enclosure boundaries, text and more), the text styles ISO-2.5 to ISO-5, the dimension style ISO-25 and an ISO A3 layout with a title block and revision table. The layer names are a common convention, not a standard; rename them to match your company's rules.

Layers defined

Every layer in the template with its colour, line weight and linetype, and how many objects of this sample are on it. Layers the sample does not use are still defined, ready for your own drawing.

Sheet and drawing setup

How the sheet is set up, so your own drawings print the same way.

Sheet: ISO A3 landscape, 420 × 297 mm.
Layout: One layout named ISO-A3, plotted at 1:1 on full-bleed A3 media, so the sheet has no printer margin.
Border: 20 mm from the left edge (binding side) and 10 mm from the other edges; the drawing area inside is 390 × 277 mm.
Model space: Units are millimetres. The drawing area is shown at 1:1, so 1 mm in the drawing is 1 mm on paper.
Title block: 160 × 79 mm at the lower right, with a four-line revision table above the company, project, title and approval fields.
Text size: 2.5 mm for labels and notes, 3.5 mm and 5 mm for headings.
Linetype scale: 1, so dashes are sized for plotting at 1:1.
Plot style: None set. Pick the CTB from the ZIP in the page setup for black-and-white plots.

How to use it

Open the sample drawing to see how layers, text and the title block are used, or open it in the browser first, nothing to install.
Start your own drawing from the template (NEW, then pick the DWT file). Copy the CTB file to your plot styles folder if you want black-and-white plots.
Insert blocks from the symbol library into your drawing. The blocks in the sample are copies; they do not change when a library changes.
