You're right -- It doesn't make since to create a solid model ONLY to tak=
advantage of 3D printing. If solid modeling is at the core of the produc=
development process, the company can use this master model data to drive
engineering, analysis, visualization, documentation, and tooling. I'm no=
telling you anything you don't already know, but it's important to keep i=
mind that if one isolates a given activity that requires you to create
computer model data, you risk losing the benefit of that activity. That'=
why integration of data is so important. The lack of intergration, coupl=
with the rigid steps that one must follow to get work done, are reasons w=
CAD solid modeling hasn't been terribly successful for highly creative
(e.g., ergonomic) industrial design work -- a task that requires fast,
flexible, and intuitive tools.
