PRODUCT DEVELOPMENT TECHNOLOGY REVIEWS » DEVELOP3D’s editor, Al Dean, looks at the latest release of SpaceClaim, the system that brought Direct Modelling back to the fore after decades of anonymity. What has the vendor got in store for its next major release? SpaceClaim 2009

he world of 3D product development technology appears Tto be in a state of fl ux. Over the past two years the movements of many vendors, new and old, have seen a rebirth of interest in a fi eld that many pundits considered to be mature, tired and almost squeezed dry of innovation. If the twenty-year ‘overnight’ success of direct modelling/direct editing has done one thing, it’s made 3D CAD interesting again. While there are many reasons that this has happened (advances in solid modelling algorithms and CPUs), it got kick started by the new kid on the block, SpaceClaim. Two years ago the company appeared out of nowhere and showed off its eponymous entitled SpaceClaim application. Much has been said about the product, which rather than relying on a construction history, adds intelligence to the model, regardless of the source. Rather than focussing on what’s new with the 2009 release, I’m going to look at 1 the system as a whole and where it fi ts into the crowded product development sector. After a tumultuous two years, things have fi nally started to settle down in terms of »SpaceClaim 2009 section through the model.

●1 This shows one of the most interesting ways of working with 3D geometry in SpaceClaim. By working at a sketch or section level, and directly manipulating the geometry, users can maintain clarity of sight on what’s going on and the effects of edits, while maintaining the 3D geometry at the same time. This makes working with certain products, such as this lens, much easier ●2 Here, a cast component is taken and the features removed for downstream processes, such as CAM 2 or FEA. Machining stock can be very quickly added to the part, which is particularly useful when the machine shop might not have access to the native geometry DEVELOP3D MARCH 2009 37 REVIEW
