We'll examine how plot styles work, highlight the differences between STB and CTB plot styles, and explain why we recommend CTB styles to minimize the confusion and maximize your time spent designing.The British Technical Drawing standards allows for three Line weights on each drawing.
#AUTOCAD PLOT STYLE NOT CHANGING LINEWEIGHTS HOW TO#

Because you are converting your office to use CTB styles, your ultimate step is to convert your lineweight-based template to a CTB template. If you are currently working with lineweight-based plotting styles, you likely have template – a DWT file that you use as a drawing template to ensure that all your drawings have a lineweight-based plotting style. BatchMan is a batch file processing tool that applies processes, including STB to CTB conversion, to multiple CAD drawings. To convert your STB styles to CTB styles across multiple CAD drawings – or across all your company's existing drawings – complete the conversion steps outlined above using our BatchMan tool. The lineweight-based styles in the drawing you currently have open will be converted to CTB styles. Now go through and assign a color to each layer depending on the color standards you set. In the Layer Properties Manger, click the top of the Lineweight column to sort your layers by lineweight. Type CONVERTPSTYLES in the Command line, and press Enter. Open your Layer Properties Manager by typing Layer in the Command line and pressing Enter. However, you'll use these same steps when converting all your existing drawings to CTB, as well as when converting your lineweight-based template to a CTB template. The following steps outline how to convert lineweight-based styles to CTB styles in a single drawing. If your office assigns a lineweight to each layer for plotting purposes, you can convert your plotting styles to CTB styles by assigning a color to each layer. Either way, it's a good idea to convert to CTB styles.Ĭonverting Lineweight-Based Styles to CTB Styles Moreover, colors are simply easier to pick out from each other in a drawing. So if you need to scale a drawing up or down for plotting, you will need to rescale each lineweight individually when you plot – a nightmare, to say the least. Lineweight-based styles are problematic because, unlike color-based styles, they don't allow global rescaling.


That's why the majority of landscape architects choose to use (and why we recommend using) a color for each plotting style – otherwise known as CTB styles. In reality, however, lineweights are difficult to distinguish from each other on a computer screen – especially one with a lower resolution. In these cases, the logic goes that the designer will be able to see the lineweights in the drawing exactly as they plot. In the example below, each layer is assigned a lineweight, and the plot styles are all set to the exact same value.

Some offices configure their plotting styles by setting a specific lineweight to each layer they will plot. Lineweight-Based Plotting Styles Overview As you develop your own plot standards, we highly recommend using an administrative document like our Pens file that you can easily print and distribute to each employee.
