# Box Girder Shape \[CBG]

The ‘Box Girder Shape’ refers to the cross section of the box girder. Different cross sections of the box girders within a project may require distinct box girder shapes to be defined in OpenBrIM. These cross sections will later be assigned to the Concrete Box Girder section of the workflow, along with their location definitions.
