Direct Model Simplification
The current trend of including the minutest of details on a CAD model is one that will frustrate many illustrators, as generally only a simplified diagram of the product is required. To help overcome this, Schott Systeme have included a new suite of 'defeaturing' tools. Based on their direct 'non feature' based 3D modeller, designs from almost any CAD system can be imported and subsequently simplified in preparation for illustration, without requiring the original CAD software. This process includes the location and automatic removal of overcomplicated 3D detail such as ribs, embossed text and logos, as well as unwanted fillets and chamfers. The result is a simplified version of the design generated in a matter of clicks, in preparation for further illustration.
Technical Outline Defeaturing
Providing an alternate approach to that of actually modifying the 3D product data, Schott Systeme have in addition supplied the user with the ability to defeature the illustration during the actual rendering process. Moreover, this approach enables the simplification of illustrations on poor quality CAD models that cannot easily be modified in 3D, in addition to instantly reducing the detail level of complex features such as screw threads and gear wheels. Simplification of these illustrations is undertaken during the rendering of an image, and by using a dedicated ‘thick and thin’ outline shader, differing line weights automatically help depict and illustrate the product in its simplest form.
About Schott Systeme GmbH
Celebrating over 25 years of CAD/CAM excellence, Schott Systeme continues to develop the software solution originally launched back in 1983. Starting out as one of the very first vector based graphics packages for the PC, their product 'Pictures by PC' as the name suggests, has evolved into one of the most mature CAD/CAM and technical documentation products available today. Being a fully integrated 2D/3D CAD, CAM and graphics package, Pictures by PC caters for all aspects of workshop machining, through to product design and documentation.
