- Product

- Device & OS

- Scenario
- Using drawing or note-taking tools on an iPad to draw straight lines.

- The ruler tool is missing or unavailable in the app interface.
Ensure your iPad is connected to the internet so you can check for app updates, and verify that you are in a note-editing view rather than a read-only mode.
Update OneNote and Check the Draw Tab
The most common reason for missing features is an outdated app version or looking in the wrong menu tab.
Microsoft frequently updates the OneNote app for iPadOS to add features or fix bugs. If the ruler is missing, updating to the latest version and ensuring you are in the correct drawing mode is the first step.
Open the App Store on your iPad, search for Microsoft OneNote, and tap 'Update' if a newer version is available.
Launch the OneNote app and navigate to the specific notebook page where you want to draw.
Tap the 'Draw' tab located at the top menu ribbon of the screen.
Look for the 'Ruler' icon among the drawing tools (usually next to the pens and eraser) and tap it to activate it on your screen.

Verify Feature Support on Your Device
If the ruler is still missing after an update, it might be temporarily unsupported in your region's current build or restricted by account type.
Try WPS Office for Note-Taking and Document Editing on iPad
If OneNote isn't meeting your needs or features like the drawing ruler are missing, try WPS Office. It offers a comprehensive suite of tools for writing, PDF annotation, and document editing directly on your iPad, all in a lightweight and free application.
- 1. Download the App: Go to the App Store on your iPad, search for WPS Office, and download the free application.
- 2. Open a Document or PDF: Launch WPS Office and tap the '+' icon to create a new document, or open an existing PDF for annotation.
- 3. Use Annotation Tools: Select the 'Annotation' or 'Draw' tab to access various pens, highlighters, and shape tools for your note-taking needs.
