Create diagrams with shape recognition in Microsoft OneNote

Shape recognition in Microsoft OneNote makes it easy to convert crudely drawn shapes into perfect circles, ovals, squares, rectangles, and triangles to help you create professional-looking diagrams and drawings.


  1. On the Draw tab, select the pen, color, and stroke thickness you want, and then tap the Shape Recognition tool near the far right of the ribbon.

  2. On the page, use your finger or stylus to draw a shape — such as a circle, oval, square, rectangle, or triangle. You can draw the shape in one stroke (for example, a circle or an oval) or with several strokes (for example, a square, a rectangle, or a triangle). For best results, be sure to connect your ink strokes as best as you can.

  3. If you make a mistake at any time while drawing ink, or if OneNote’s recognition of the shape is not what you wanted, you can tap the Undo arrow near the top left corner of the app to undo the last action, and then try again. If necessary, you can tap the Undo arrow repeatedly to step back in your drawing as far as you want.

  4. If you want OneNote to stop recognizing and correcting shapes, tap the Shape Recognition tool near the far right of the ribbon once more to turn off shape recognition.
