Visio does not support fitting a line of text to a curve. You can, however, create text that follows a curved path using WordArt in Word or PowerPoint. You can then copy and paste the WordArt into Visio.
Note
For information about how to create WordArt in Word or PowerPoint, see Insert WordArt.
To copy and paste WordArt into your Visio diagram:
- Select the WordArt, and press Ctrl+C.
- In the Visio diagram, press Ctrl+V.
