based CAD for the Rest of Us   Three-dimensional (3D) modeling
is no longer an issue on a personal computer (PC).  But what has
yet to be proved is whether the "personal" part of a PC also
applies to improving personal productivity—both for "casual" and
for "high-end" computer-aided design (CAD) users.  For many
people—especially casual users—increasing personal CAD
productivity is akin to making the CAD system "accessible." This
means making it easy to use. It means ensuring that the hardware
requirements—processor and random access memory—are affordable,
if not already on the desktop. And it means providing a heckuva
lot of functionality at bargain-basement prices.  A new

associativity and interoperability capabilities, and artificial
intelligence.  Reva
