The Aggregate12Type defines the geometric entity 'aggregate_curve(t):R1->R2'. The 2D curves are normally used to define a trimming curve in the parametric space of a surface.
The optional label attribute is the model entity "nameplate". Normally it can be seen at the entity item in the project tree.
