We live in a three-dimensional world.? To design objects for everyday living?? users must learn how to create in three dimensions.? For precise modern designs that must conform to specific tolerances?? we use computers to create a digital model first?? and then pass that model on to a machine?? such as a CNC router or 3D printer for fabrication.?

????? There are many software packages that are used to create digital models.? One such package that is popular for industrial?? product?? and graphic design and architecture is Rhinoceros 3D?? or ??Rhino.??? Grasshopper is a visual scripting platform for Rhino.? With it?? the user can build precise?? customizable Rhino objects by simply dragging boxes around the screen and connecting them with virtual ??wires.??? No knowledge of programming is necessary!?
