Drawing without Drawing

Parametric modeling integrates both experimental design (CAD) and its realization (CAM) and verification (CAE). It is susceptible generative systems variations and 'mutations', based on parameters that are translated into a pro gramming language by 'genetic algorithms', as the named John Holland in 1970. This raises the possibility to operate, simultaneously, with multiple solutions, for the sake of ideation and prototyping later. These prototypes programmatically parameterized with Grasshopper, may even become smart objects with Arduino hardware microprocessor programming electronic components.
