ArchiCAD is a complex architectural design tool offering 2D and 3D drafting, visualization and documentation functions for architects and planners to create three-dimensional designs and detailed technical documentation, thus enabling architects to use ArchiCAD from the earliest design phases to the technical detail drawings [REF].
