Search for third-party shapes and stencils
If you need more shapes than a particular Visio template provides, you have a couple of options. You can search for shapes and stencils that are local to your device. You can also search for stencils that are online, created by third-parties or even Microsoft.
For more information about how to search for third-party shapes and stencils with Visio Pro for Office 365, see Find more shapes and stencils.
