Why Is AutoCAD Not Plotting?

AutoCAD is a powerful software used by professionals in various industries, such as architecture, engineering, and design, to create precise and detailed drawings. However, there may be instances when you encounter issues with plotting your drawings. In this article, we will explore some common reasons why AutoCAD may not be plotting correctly and provide solutions to help you resolve these issues.

1. Plotter Configuration

If your drawings are not plotting as expected, the first thing you should check is your plotter configuration. The plotter configuration determines how your drawing will be printed or plotted on a physical device.

To access the plotter configuration settings in AutoCAD:

  1. Go to the “Print” or “Plot” dialog box.
  2. Select the desired plotter from the list.
  3. Click on the “Properties” button.

Ensure that the correct paper size, orientation, and other settings specific to your plotter are selected. It’s also important to verify that you have the necessary drivers installed for your plotter.

2. Plot Style Table

The plot style table (CTB or STB) defines how colors and lineweights are represented when plotting a drawing. If your drawing is not plotting with the correct colors or lineweights, it could be due to an issue with the plot style table. To check and update the plot style table:

  1. Navigate to the “Plot Style Manager” by typing PLOTSTYLE in AutoCAD’s command line.
  2. Select the appropriate CTB or STB file for your drawing.
  3. Click on “Set Current” to apply the selected plot style table.

Ensure that the plot style table you are using is compatible with your drawing and contains the correct color and lineweight settings.

3. Layer Properties

Another common reason for plotting issues in AutoCAD is incorrect layer properties. If certain elements of your drawing are not appearing or printing as expected, check their layer properties. To modify layer properties:

  1. Type LAYER in AutoCAD’s command line to open the “Layer Properties Manager”.
  2. Select the layer containing the problematic elements.
  3. Verify that the correct color, linetype, and lineweight are assigned to the layer.

If necessary, make adjustments to ensure that the layer properties align with your desired plotting outcome.

4. Drawing Scale

Inaccurate plotting can also occur if your drawing scale is set incorrectly. The drawing scale determines how measurements and objects in your drawing relate to real-world dimensions. To adjust the drawing scale:

  1. Navigate to the “Drawing Scale” option in AutoCAD’s status bar.
  2. Select a suitable scale from the drop-down list or choose “Custom” for a specific scale ratio.
  3. Verify that you have set the correct units for your drawing (e.g., inches or millimeters).

5. Plot Preview

If you are still experiencing issues with plotting, it can be helpful to preview how your drawing will be plotted before sending it to print. The plot preview function allows you to visualize any potential problems and make adjustments accordingly. To use plot preview:

  1. Go to the “Print” or “Plot” dialog box.
  2. Click on the “Preview” button.
  3. Inspect the previewed plot and look for any anomalies or discrepancies.

If you identify any issues, go back to the previous steps in this article to troubleshoot and correct them before proceeding with the final plot.

In conclusion, plotting issues in AutoCAD can be frustrating but can often be resolved with some troubleshooting. By checking your plotter configuration, plot style table, layer properties, drawing scale, and using the plot preview function, you can address common problems and ensure accurate and successful plotting of your drawings.
