Computer-aided design (CAD) software modernized drafting, bringing it into the digital age. But while it increased productivity and merged the roles of draftsmen, designers and engineers, it did little to empower those outside these specialized fields. Software for other fields however, has enabled a wide range of people to do things previously limited to a small group of experts.

Similarly, 3-D modeling software should be so easy to learn that anyone can mock up an idea.
