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 whole hotel floor, drawn with the palette

Ten guest rooms, a corridor, a lift lobby and a riser room: 314 devices from the Pro palette - room control, lighting, sockets, fire alarm, security and data - placed, tagged and counted on one sheet.

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 symbols are blocks from our own libraries, with their attributes filled in. The sheet and its title block come from our ISO A3 title block template. Download them to draw your own diagrams.

The template

The architectural template has 10 layers with colours, line weights and linetypes (walls, floor finishes, hidden elements, column grid, symbols, escape routes, tags, dimensions, text and notes), 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.

Styles defined

The text styles, the dimension style and the linetypes that the template defines, so you do not have to set them up in each new drawing.

Text style	TB-en	Arial, used by the title block
Dimension style	ISO-25	Text 2.5 mm, arrows 2.5 mm, extension lines 1.25 mm beyond the dimension line and 0.625 mm from the object, dimension lines 3.75 mm apart, 0 decimals
Linetype	Continuous	Solid line
Linetype	DASHED	Dashed
Linetype	DASHDOT	Dash-dot
Linetype	CENTER	Centre line
Linetype	PHANTOM	Phantom line
Linetype	HIDDEN	Hidden line

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.
