Illustrator 26.4.1 missing save to DXF

Hi @krzysztof255671842llj,

Sorry about the trouble you are facing. I would like to know if you were able to locate the "save to DXF" as suggested by @Kevin Stohlmeyer? If not, would you mind sharing a few more details like:

• Did this start happening after upgrading to 26.4.1?
• What is the Windows 10 build no.?
• What is the canvas/ artboard resolution of the file you are trying to export as DXF.? Does reducing the artboard size help you get the export option?
• Are there any recent changes made to your system? For example, any antivirus, system updates, or web extensions installed recently.
• Does resetting Illustrator Preferences (https://helpx.adobe.com/in/illustrator/using/setting-preferences.html) help to resolve the issue?
  Disclaimer: Please note that resetting preferences will remove all the custom settings, and Illustrator will launch with default settings. You can also take a backup of the folders in case you want to. Location is mentioned in the article.
• Would you mind checking if installing the previous version of Illustrator resolves the issue or not?

We are here to help. We just need more info.

Thanks & Regards,

Anshul Saini

You'll find it under Export As.. not Save As.
