 data to physics codes that support sub-block geometric modeling. This page will talk about
 how spatial information is assigned to components on a block, how spatial data can be assigned
 and accessed, and how those data may or may not be updated by the framework.

 Blueprints
 ----------
 
 In your blueprints file, you likely have a core grid that defines where assemblies reside in the reactor. Assemblies
 are assigned to locations on that grid according to their ``specifcier`` blueprint attribute. Below is an example
