Appliance Design - September 2008 - (Page 58) SOFTWARE SpaceClaim can open, assemble and edit 2D and 3D CAD data from diverse CAD systems. To preserve the critical design intent in the original CAD models, SpaceClaim works with a copy of the data. SpaceClaim then provides accurate solid models and markups of the changes for the production CAD users. have an economic incentive to ignore the problem, because the cost to customers of switching systems, migrating legacy data, and retraining users locks the customer base and often the supply chain to one CAD system. This burden has created a strong latent demand for a solution that lets the extended development team create and edit 3D data regardless of its origin and without becoming experts in the details of history-based modeling. Increasing access Many stakeholders in the design process should be able to work with digital design data, including conceptual engineers, industrial designers, CAE analysts, manufacturing engineers, technical writers, purchasing, supply chain management, and marketing. These contributors are typically not effective CAD operators, because that is not their primary job. They need design tools that permit them to influence and communicate with detailed designers. These tools do not replace production CAD tools. Instead, they enable the extended team to create and work with the CAD data without being CAD experts. 58 applianceDESIGN September 2008 Interactions with detailed design typically fit into three workflows: Concept and specification: Using concept models prior to detailed design so detailed designers can figure out how they are going to structure their feature models. A 3D design tool that allows rapid modeling without the constraints of history-based modeling allows concept teams to make unplanned, creative decisions and converge quickly on the solutions to be detailed. For example, conceptual engineering, conceptual analysis, industrial design, and suggestions from management are common groups that require more versatile tools to provide 3D input to the detailed design teams. Engineering change requests: Specifying changes to existing models, which usually involves changing design intent and rewiring the history-based model. With a 3D design tool, engineering change orders can include an edited solid model that accurately communicates the change. For example, changes are commonly issued by CAE analysts, quality assurance, manufacturing, and field engineers. www.applianceDESIGN.com http://www.elec-troninc.com http://www.appliancedesign.com
