Generative Design

The future of CAD

Whatz the clouds got to do with it ?

The cloud brings together the possibility of massive computational resources and connectivity in an unprecedented scale across a wide range of business, educational and entertainment activities.

Are the Architects ready for the cloud?

The answer is ” No”.  But, will they get there? ” Yes”. Most likely, in the  same wrong way they adopted CAD – to replicate the drawing board with CRT screens  – without consideration to the true potential of computers. This was a big jump for many architects. It happened  only because they were assured that the Cathode Ray Tube (CRT) was better than the drawing board. Companies such as Amazon, Microsoft, Apple and Autodesk are all now busy building the rail roads in the kingdom in heaven – in which platforms of great promise will dominate the next era of human dependence on computation. So, everyone will get there for sure.

But what will design be in the cloud ?

I believe that the cloud will  initially be used in the same way that computers were used to replace existing PC based practices. PC bound CAD systems will soon be operating on cloud platforms. Speed and connectivity bonuses are good enough to lure most CAD dependent designers. But once they are all there, it is likely to transform the practice of design in way that it was transformed by the PC/CAD revolution. But then, without them realizing it, the clocks will be turned back on them. Design processes will go back a few billion years – to where design began.

Design will be – as in nature

Nature in itself  is a massive computational environment that has evolved over billions of years. Its key virtues of building complexity based on shared code and ability to explore possibilities through random exploration using highly evolved strategies and methods will come to dominate the art of design – orchestrated by human designers, the way humans have harvested the potential of natures design capability to turn grass in to wheat and rice and wolf into dog; primarily by manipulating a highly evolved refined and structured design processes.

Design as it is now

Before we consider the lofty heights that clouds can take us to, let’s review where we are with CAD now. The turbocharged drafting machines now connected to data-bases powered graphically by games technologies have got us quite far. A diverse set of capabilities and professional work practices – are now slowly coming together; but mostly at the back-end of the design process. But here it is too late, as all the important designs are already made and opportunities to make significant improvements are limited. It is known that more than 80% of decisions and commitments are made in the early stages of the design process (shaded in green) where now computers play a very limited role.

The codification and comodification of CAD

Most CAD packages now handle the drudgery of 3D manipulation fairly well. The dark regions shown – is dominated by code that reduce design labor ( most CAD companies have similar capabilities in this area). The push now, is into early stage design, where significant improvements can be made. Software like Grasshopper and platforms like Vasari are now extending the reach of CAD into early stage design. Further up stream is generative design.

What the clouds mean for generative design?

It is like asking what gasoline means for your car? Generative design can drink it all – all the computational capabilities that the cloud can provide. It will soon be possible to roll apparently dumb, random and computationally intensive approaches that nature has chosen in its great wisdom. Hopefully, it will be based on an open and shared genetic infrastructure – so that knowledge generated will not be lost but be shared and built upon.

The fundamental change will be the ability to consider multiple possibilities in virtual environments. In sharp contrast to the singular and somewhat perturbed linear approach mastered by designers on account of their limited mental processing capabilities. The design processes now used by designers are based on the limits of the processing capability of the human mind and its ability to consider only a large but limited number of possibilities. Kasparov is no longer the champion of chess.

The maturing of many CAD technologies has already greatly reduced the human labor in taking early stage concepts to reality that is close to real, making it possible to consider multiple possibilities of great maturity – instead of dumping them at the end of a doodling process as part of an ancient design ritual.
