Autocad standard line weights – No. 2

Following on from our last post about Autocad line weights, plot styles etc – we have had a query from one of our readers about what the standards are for line weights when drawing, for example, windows, walls and so on.

So, to make it easy for you guys we have put together a template model file for you to download. The model file contains basic standard layers to use when drawing. The colours of these layers correspond with the plot style file that you can also download here. We figured this was the easiest way to demonstrate the standard line weights for objects.

Layer Standards

How to use the template:

This is super simple – either save the dwg file and use it every time you start a new drawing – this way the layers are already set up. Or, you can copy and paste the layers from the template file into your own drawing.

How to use the Plot Style:

The plot style file is for when you print (or pdf) a drawing. This contains the line weights that correspond with the layer colours. All you need to do is put the ctb file into the plot style location. This is usually in Autodesk/AutoCAD 2013/Contents/UserData/Plotters/Plot Styles or something like this depending on your version and operating system. Then when you go to plot, select plot style, and find the FIA plotstyle template. Simple!

Hope you found this post useful – hit us up with any comments, we would love to hear what you guys think of the website – and what else we can do to help.

  1. hi, thanks so much for your template! Just one question though, what scale is this plotstyle designed for? I ask this because different scales require different lineweights for the same objects.

    • Hi, thanks for your question. This layer set up and plot style should work with pretty much any scale. I use a similar one for most of my drawings – so it works well for A3 1:100, 1:50 drawings. However, if doing detailed drawings at A1, then it seems to work ok for that too. Sometimes I create a couple of extra layers/colours and edit my plot styles if I am needing more line widths.
      Generally your scale corresponds with the paper size you are using – so the line weights should work. Hope that helps but if you have any more questions just ask!

  2. Hi, both of these seem incredibly useful. I’m new to CAD and computer drawing, I successfully loaded your Plotstyle and Layer, however in the Layer Template there were no lineweights assigned to each layer. Could you help me out?

    • Hi Patrick, I don’t assign line weights to layers, I tend to use the plot style to assign line weights. What this means is when you come to print or pdf the drawing, if you select the plotstyle the line weights will then show up on the print out at the different thicknesses according to the colour. So effectively the layer colours are the line weights. Hope that helps…

  3. A much better way of doing it is to assign a lineweight to each layer then plot with monochrome. That solves the problem of emailing drawings around and the recipient not having (or not understanding how to use) your custom .CTB file.

    • Hi Paul,
      Good point. I think the trouble is that there are so many different ways of doing it, and usually most practices have their unique standards and guidances so it varies from one person to the next. I don’t use the method you suggested personally, and have never worked anywhere that does it like that – but it certainly seems like a good option. Thanks for your thoughts – much appreciated. 🙂

  4. Good post! We are linking to this great article on our website.
    Keep up the great writing.

  5. This was VERY useful for my Acad works. Really helps my designs/drawings. Much thanks \!

  6. can i get the line weight values in mm.

  7. How do you see your line weights as they will be printed in the paper space rather than the allocated colours?? thanks 🙂

    • Hi Lucy, the best way is to print a pdf to preview your work. I am not aware of any other way of previewing the line weights.
