AutoCAD 2026 Known Issues

This topic contains important information for Autodesk AutoCAD.

DWG Convert, Etransmit, and Archive

The ZIP option of the DWGCONVERT, ETRANSMIT, and ARCHIVE commands now creates UTF-8 ZIP files. This uses the popular 8-bit form of Unicode for file names. You can package files with names that have extended font characters. However, the file names do not display correctly if you use ZIP utilities that don't support UTF-8 ZIP files. Use a ZIP utility such as 7-Zip to correctly display and extract these files.

Feature-Specific Requirements

  • Starting with AutoCAD 2017-based products, BMP files no longer support the color value of 192,192,192 as a transparent color. Custom images that need to support transparency must be saved as PNG files.

  • AutoCAD’s Data Extraction workflow automatically uses Microsoft’s Access Database Engine by default when it’s available on your system. If the Access Database Engine is not available, the Jet Database Engine is used as in previous releases.

  • Using ACCoreConsole to publish only publishes drawings using software Z-buffer rasterization. To plot using hardware-accelerated rasterization, plot or publish through AutoCAD. BGCorePublish utilizes ACCoreConsole and should be turned off to use hardware-accelerated rasterization.
