Used to retrieve a Live Blueprint and have it show up on the page.

This macro allows a user to reuse a blueprint and its substitution fields on pages throughout a site. When the blueprint is subsequently updated, every page using that live blueprint will automatically be updated. 

Because Live Blueprints are not accessible in the Blueprint Menu, the Live Blueprint Macro is the only way to reference Live Blueprints. You can use multiple Live Blueprint Macros on a page, each with its own unique data if substitution fields were used in the Live Blueprint.
