Combing Through 3D CAD Programs

Look around. Nearly everything that you interact with was likely a creation of three-dimensional computer-aided design (3D CAD) — homes, furniture, automobiles, lighting, smartphones, computers. At its most basic level, a CAD program takes a designer’s two-dimensional sketch and extrudes, or solidifies, that drawing into a three-dimensional model. Depending the industrial focus of the CAD program, and the modular extensions used to support and enhance its software, product developers and engineers are able to design extremely intricate products that can be built or manufactured. At Proto Labs, every single part submitted for manufacturing arrives as a 3D CAD model in one of several different file formats derived from different CAD programs. Continue reading
