Fix AutoCAD PDF Text Appearing as Dots in Adobe Acrobat
Question details
The user needs to resolve an issue where text in a PDF exported from AutoCAD does not render correctly in Adobe Acrobat.
- Product
- Adobe Acrobat and AutoCAD
- Device & OS
- not provided
- Scenario
- Opening and viewing an AutoCAD-generated PDF file in Adobe Acrobat.
- Observed behavior
- Text elements within the PDF appear as dots instead of readable alphanumeric characters due to missing or unembedded fonts.
Ensure you have access to the original AutoCAD (.dwg) file, as the most effective and permanent fix requires re-exporting the PDF with the correct font settings.
Enable Font Embedding in AutoCAD PDF Export Settings
The best way to ensure text displays correctly in any PDF viewer is to embed the fonts directly when creating the PDF in AutoCAD.
When AutoCAD exports a PDF without embedding the fonts, Adobe Acrobat relies on your local system fonts to display the text. If the specific CAD font is missing from your computer, Acrobat will display dots. Embedding the fonts forces the PDF to carry the text data with it.
Open your drawing in AutoCAD and initiate the 'Plot' or 'Export to PDF' command from the main application menu.
Select 'DWG to PDF.pc3' or your preferred PDF plotter from the printer/plotter dropdown, then click on the 'PDF Options' button.
Under the Data section in the PDF Options dialog, check the box labeled 'Capture fonts used in the drawing'.
Click 'OK' to save these settings, and proceed to export or plot your PDF again. The new file will contain the embedded fonts.
Verify Font Embedding and Use Local Fonts in Adobe Acrobat
Verify if the fonts are actually missing from the PDF and try using local system fonts as a temporary viewing workaround.

Frequently Asked Questions
Why do some PDF viewers show the AutoCAD text correctly while Acrobat shows dots?
Different PDF viewers handle missing fonts differently. Some lightweight web browsers or viewers automatically substitute missing fonts with standard system fonts to force the text to render. Adobe Acrobat, however, strictly adheres to the PDF's font dictionary and will display dots if the exact font isn't embedded and cannot be accurately mapped.
Can I fix the dots in the PDF without having access to AutoCAD?
It is very difficult to fix permanently without the source file. If the fonts weren't embedded during creation, the PDF lacks the necessary shape data for the text. You would need the original author to re-export the file with 'Capture fonts' enabled in AutoCAD, or you must install the exact missing CAD font on your local computer.
What does 'Embedded Subset' mean in PDF font properties?
'Embedded Subset' means that only the specific characters used in the document are saved within the PDF, rather than the entire font family. This keeps the file size small while ensuring the text displays perfectly on any device.
