SpaceClaim were minimal. You could open up mesh fi les, observe, and maybe reference any given facet. To appreciate today’s capabilities though, you have to be aware of a mis- conception in the market that reverse engineering is a simple fi le transfer: click a couple of buttons, some translations happen, and out comes a clean CAD fi le—similar to translating a language. There’s a lot more going on behind the scenes that the average person needing to reverse engineer just didn’t understand. Space- Claim began developing some wonder- ful tools, where reverse engineering of fi les is closer to a few button clicks. Much functionality has been squeezed into one tool that essentially autosur- faces mesh data. Users can quickly create clean surfaces and solid bodies
for downstream applications. ME: What other key tools does the
software provide for additive manufac- turing, which is seeing an explosion in
interest by manufacturing? Graham: Roughly a decade ago when SpaceClaim emerged, it was groundbreaking. It took a new technol- ogy called direct modeling to a whole new level and made 3D modeling ac- cessible to any engineer. Today you’re seeing some solid-modeling capabilities making their way into the faceted data sphere, much like it happened a de- cade ago. For example, you can grab a couple of facets and move them, or pull on what looks like a hole and increase or decrease the diameter. You can use SpaceClaim to repair or perform Boolean operations on faceted data, in a similar way to CAD fi les. In a way, I liken work in SpaceClaim to working in digital clay. Anybody can visualize what it is they want, and SpaceClaim is mak- ing the digitization of that a reality. Another important aspect of SpaceClaim in the 3D printing realm is optimization.

to shell any kind of fi le and add an infi ll to it. This balances the strength-to-weight ratio. It can also smooth out an STL, with a tool called shrinkwrapping, by essentially wrapping a blanket over it and ignoring small irregularities or spikes in the model.
