Fix Repeated Prompts When Converting AutoCAD DWG to PDF in Acrobat
Question details
The user encounters repeated prompts and interruptions when attempting to combine AutoCAD 2019 DWG files into a single PDF using Adobe Acrobat Pro 2017.
- Product
- Adobe Acrobat Pro 2017, AutoCAD 2019
- Device & OS
- not provided
- Scenario
- Combining multiple AutoCAD DWG files into a merged PDF document.
- Observed behavior
- Acrobat triggers continuous pop-up prompts during the conversion process, likely due to file format incompatibility.
Ensure you have saved all active AutoCAD projects to avoid data loss and verify that you have administrative privileges to install any necessary software updates.
Export to PDF Directly Within AutoCAD (Recommended)
Bypass the Acrobat conversion engine entirely by exporting your DWG files as PDFs directly from AutoCAD, then combine the PDFs in Acrobat.
Adobe Acrobat Pro 2017 often struggles with newer DWG formats created by AutoCAD 2018 or 2019. Creating PDFs natively in AutoCAD before combining them is the most reliable workaround.
Launch AutoCAD 2019 and open the DWG file that is causing the prompts.
Navigate to the Application Menu (the 'A' icon at the top left), select 'Export', and click on 'PDF'. Choose your preferred PDF quality settings and save the file.
Export the remaining DWG files as individual PDFs to a local folder.
Open Adobe Acrobat Pro 2017, select the 'Combine Files' tool, and add the newly exported PDFs to merge them without format prompts.
Save DWG Files to an Earlier Compatible Format
Save your AutoCAD 2019 files as an older DWG version to ensure compatibility with Adobe Acrobat Pro 2017.
Update Acrobat and AutoCAD Components
Ensure both software programs are updated to their latest versions to patch known conversion bugs.
Easily Merge and Manage Your PDFs with WPS Office
After exporting your AutoCAD designs as PDFs, use the WPS Office PDF toolkit to quickly combine, edit, and organize them. It provides a smooth, crash-free experience for merging high-quality design documents.
- 1. Open WPS PDF: Launch WPS Office and click on the 'PDF' tab to open the PDF toolkit.
- 2. Select Merge PDF: Click on the 'Merge PDF' tool located on the main dashboard.
- 3. Add Your Exported Files: Click 'Add Files' and select the PDF files you exported from AutoCAD.
- 4. Combine and Save: Arrange the files in your desired order, click 'Merge', and save your combined PDF document.
Frequently Asked Questions
Why does Acrobat Pro 2017 prompt repeatedly when converting AutoCAD 2019 DWG files?
This occurs because Acrobat Pro 2017's internal conversion engine does not natively support the newer DWG file structure introduced in AutoCAD 2018 and later. The mismatch causes Acrobat to repeatedly trigger compatibility warnings.
Does saving the DWG to an older version affect my drawing quality?
Saving to an older format like AutoCAD 2013 DWG generally retains your layout and visual quality for printing or PDF conversion. However, you might lose the editability of certain advanced features specific to AutoCAD 2019 if you reopen the file to edit.
Can I merge DWG files directly into one PDF without having AutoCAD installed?
Directly merging DWG files into a PDF without AutoCAD usually requires third-party CAD viewing software or dedicated conversion tools. For the most accurate result without errors, exporting to PDF from the native AutoCAD application first is highly recommended.
