Orbi by ar_grasshopper_collective_thn is a plug-in for Grasshopper that generates patterns parametrically with symmetry groups. Orbi allows to select a symmetry group and define any geometry as the fundamental region of a pattern. The fundamental region is the smallest part that is repeated in a pattern.

In Orbi the shape of the fundamental region is displayed and used as drawing area for an input
geometry. The fundamental region can be freely arranged and oriented in space. Once the fundamental region and the symmetry group are defined, the corresponding pattern is generated automatically.
