smart guides not showing

Hello @Jolyn28220540napo,

We understand that encountering technical issues can be frustrating. I hope the suggestions shared by Jacob and Met1 helped resolve the problem. If not, kindly try manually resetting Illustrator's preferences to check if it helps:

For macOS
• Close all Adobe applications.
• Go to the following locations
• ~/Library/Caches
• ~/Library/Application Support/Adobe
• ~/Library/Preferences
• Rename Adobe Illustrator, com.adobe.illustrator and Adobe Illustrator 27 Settings folders to Adobe Illustrator.old, com.adobe.illustrator.old and Adobe Illustrator 27 Settings.old
• Launch Illustrator from the Creative Cloud.

Note: Location starting with this "~" sign indicates the User Library, which is hidden. So, you need to copy & paste the exact path in spotlight search or from Finder Menu > Go > Go to Folder > Paste the location in the dialog box like this:

For Windows
- Close all Adobe applications.
- Go to Location C:\Users\%USERPROFILE%\AppData\Roaming\Adobe
- Rename Adobe Illustrator and Adobe Illustrator 27 Settings folders to Adobe Illustrator.old and Adobe Illustrator - 27 Settings.old

Disclaimer: Please note that renaming preferences folders will remove all the custom settings, and Illustrator will launch with default settings. You can also save a backup of the folders in case you want to. The location is mentioned above.

Looking forward to your response.

Thanks,

Anubhav

Has to be asked - do you have Smart Guides turned on?

Jolyn,

There are different kinds of guides, one of them being the Smart ones, and what you see for them dpends on the settings.
