FAQ: Autocad File Conversion to PDF Issues

1. Can I convert AutoCAD files to PDF in AutoCAD LT?

Yes, you absolutely can. AutoCAD LT, despite being a more streamlined and less feature-intensive version of AutoCAD, still allows users to convert their DWG files to PDF. Just like in the full version of AutoCAD, you can find this feature in the ‘Plot’ or ‘Print’ menu, where you should see ‘DWG to PDF’ listed as a printer. Select this printer, specify your desired settings, and proceed with the ‘Print’ command to generate a PDF.

This feature in AutoCAD LT not only provides convenience for design professionals needing to share their work but also maintains the integrity of the design. The high-quality PDF preserves all the details of the DWG file, ensuring that what you see in AutoCAD LT is what you get in the PDF. However, it’s worth noting that if the built-in conversion feature is unavailable, you might need to try troubleshooting methods similar to those for the full version of AutoCAD.

2. Can I convert AutoCAD files to PDF on a Mac?

Yes, you can. AutoCAD for Mac, similar to its Windows counterpart, allows for the conversion of DWG files to PDF. The process is straightforward. You simply need to choose “Print” from the File menu, then in the Printer dropdown menu, select the “Print to PDF” option.

This versatility of AutoCAD across different operating systems means that whether you’re using a Windows PC or a Mac, you can create, share, and print your designs in the universal PDF format. In case you encounter difficulties in the conversion process, the methods and steps for troubleshooting are generally the same across both platforms. It’s worth remembering that external factors like printer drivers and software compatibility might also affect the process.

3. Why are my converted PDFs losing quality?

The loss of quality in the converted PDF can be attributed to several factors. The settings used during the conversion process can significantly affect the quality of the final PDF. For instance, if you’re using a raster graphics configuration instead of a vector one, the result may not retain the sharpness and precision of the original DWG file.

AutoCAD provides an array of settings for PDF conversion, including options for quality enhancement. You can adjust these parameters under the ‘Options’ button in the ‘Plot’ dialogue box. Here you’ll find settings for vector graphics, gradient hatches, lines merge, and more. It’s always good practice to experiment with these settings and preview the results before finalizing the conversion.

4. What do I do if AutoCAD crashes during the conversion process?

If AutoCAD is consistently crashing during the conversion process, it could be a sign of a deeper software issue. You might be dealing with an installation problem, a corrupt DWG file, or even a lack of system resources, which could cause the software to crash under the heavy processing load of conversion.

Lastly, ensure your computer meets the system requirements for running AutoCAD, as resource limitations could also be causing the crashes.

5. How can I batch convert AutoCAD files to PDF?

Batch conversion of DWG files to PDF can be a real time-saver, especially when dealing with multiple files. AutoCAD has a built-in feature for this – the Batch Plot. You can access this feature through the ‘Application Menu’, where you select ‘Publish’. Here you can add multiple DWG files to the list and select ‘DWG to PDF’ as the printer.

Remember that batch conversion is a demanding process and can be resource-intensive. Therefore, ensure your computer has adequate processing power and memory to handle the task. Additionally, monitor the conversion process, as errors in one file could halt the entire batch conversion process.

6. Why are layers not preserved when converting to PDF?

When you convert a DWG file to PDF, the expectation is that all elements of the file, including layers, will be preserved. However, sometimes layers might not be visible in the PDF. This can be caused by settings not being properly configured to include layers during the conversion process.

In the Plot dialogue box, under the DWG to PDF.pc3 settings, ensure the ‘Include layer information’ box is checked. This ensures that your PDF will preserve and display the layer information from your AutoCAD file. Remember, layer visibility in the PDF might also depend on the capabilities of the PDF viewer you are using.

7. Are online conversion tools safe for converting AutoCAD files to PDF?

Online conversion tools can be a handy solution when in-built or third-party software solutions aren’t available or working. However, when it comes to safety, it largely depends on the specific tool you’re using. As these tools require you to upload your DWG files to their servers, you should be aware of the potential security risks involved.

Before using an online converter, check if the website uses a secure connection (https). Read through the tool’s privacy policy to understand how they handle your data. Some reputable online conversion tools commit to automatically deleting your files after a certain period, which can provide some peace of mind. Always remember, if your files contain sensitive or proprietary information, using a secure, offline conversion method is recommended.


While encountering the “Conversion of AutoCAD files to PDF has been disabled” error can be frustrating, there are various ways to resolve the issue and alternative methods for converting your files. Navigating through these challenges not only ensures your work proceeds without interruption but also helps you better understand and use your software tools.
