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
