RE: Visio
Hello Gillian
Thank you for your question, and apologies for the unusually long delay in response.
To align shapes in Visio:
1. Select the shapes you wish to align (click on one shape, hold down Shift while clicking on the other shape or shapes you wish to select, then release the Shift key).
2. On the menu, select Shape - Align Shapes.
3. Choose the desired alignment option, and click OK.
I hope this helps.
Amanda
