Fix Missing Text and Drawings in AutoCAD PDFs Opened in Acrobat 2017
Question details
The user needs to resolve an issue where a PDF exported from AutoCAD fails to display certain text and drawing elements when opened in Adobe Acrobat Pro 2017.
- Product
- Adobe Acrobat Pro 2017
- Device & OS
- not provided
- Scenario
- Opening and viewing a complex PDF file exported from AutoCAD.
- Observed behavior
- Text and drawings are missing or fail to render in Acrobat Pro 2017, even though the same PDF displays perfectly in Chrome and Adobe Reader DC.
Before adjusting application settings, verify that your graphics drivers are up to date and close any background applications that might interfere with rendering software.
Modify Display and Rendering Preferences in Acrobat
Disabling hardware acceleration and adjusting page display cache settings often resolves rendering conflicts for complex AutoCAD PDFs.
Acrobat 2017 attempts to use your system's graphics card to smooth out and render 2D graphics. However, complex CAD exports can sometimes clash with this hardware acceleration, resulting in blank or missing elements. Modifying these display preferences forces the software to use a more stable software rendering path.
Launch Adobe Acrobat Pro 2017, click on the 'Edit' menu at the top, and select 'Preferences' (or press Ctrl+K).
In the left-hand category pane of the Preferences window, select 'Page Display'.
Under the 'Rendering' section, uncheck the box for 'Use 2D graphics acceleration'. You may also want to uncheck 'Use page cache' to ensure the document is redrawn fresh.
Click 'OK' to save the changes. Close Acrobat entirely and reopen your AutoCAD PDF to verify if the missing elements now appear.
Update Adobe Acrobat to the Latest Patch
Applying the latest official patches can fix known bugs related to rendering PDF files exported from third-party software like AutoCAD.

Frequently Asked Questions
Why does my AutoCAD PDF look fine in Chrome but not in Acrobat?
Web browsers like Google Chrome use different, often simpler, built-in PDF rendering engines (like PDFium) compared to Adobe Acrobat. If a PDF contains complex CAD layering or specific graphical encodings, Acrobat might try to render them using advanced hardware acceleration, which can sometimes fail or hide elements if there is a graphics driver conflict.
Can exporting from AutoCAD differently prevent this missing text issue?
Yes. When exporting from AutoCAD, using the built-in 'DWG to PDF.pc3' plotter or adjusting the PDF export options to embed all fonts and flatten layers can greatly improve rendering compatibility with older versions of Adobe Acrobat.
Will resetting Adobe Acrobat preferences delete my saved PDF files?
No. Resetting or changing Acrobat's preferences only modifies the application's default behaviors, such as display settings, viewing modes, and interface configurations. Your actual PDF documents and saved data will remain completely unaffected.
