Streamlining Concept Design and Downstream Engineering – Choosing the Right Tools For Successful Workflows
December 23rd, 2011 by Jeff Rowe
A recent study entitled, “Trends in Concept Design,” conducted by PTC, found that the majority of respondents are recreating concept designs once the concept design is released to downstream engineering stages. For example, recreating drawings, sketches, and models that were generated during the concept phase and released to the engineering department for further development. This approach is known as throwing a design “over the transom,” not knowing how the final product will be realized as compared with the original design intent from the concept phase.
Clearly, this approach is not only inefficient, but also usually contributes to too many unexpected and undesirable results between the concept stage and the marketplace.
Fortunately, today there are tools and approaches to help manufacturers eliminate the need for data recreation, streamlining the concept design stage of product development and downstream engineering processes. Even at the concept stage, manufacturing companies are increasingly reusing existing design data instead of creating everything from scratch – a potential big time saver reusing design data that is already known to work.
At the concept stage, using a tool, such as Creo Direct, you can create regular geometry for 3D purposes. In Creo Direct, you can create and edit 3D designs through direct interaction with their geometry. You can make changes to the basic design elements at any point with little impact to the overall design process. The resulting geometry is compatible with all the Creo applications, including Creo Parametric that is used for refining designs downstream in the product development process. In fact, even 2D sketches captured with Creo Sketch are compatible with Creo Parametric.
The Creo Sketch and Creo Direct user interface is similar to that of Creo Parametric, and so supports and streamlines the design process.
Creo Parametric can share data seamlessly with other Creo apps, notably Creo Direct and Creo Simulate. This means that time is not wasted on data recreation or translation, resulting in costly errors. Users can seamlessly move between different modes of modeling and 2D and 3D design data can easily move between apps while retaining original design intent. This all provides a very high level of interoperability productivity gains throughout many product development processes between design and engineering groups.
In the end, successful product development, from the concept stage, to engineering, to production all comes down to interoperability between the various groups at various stages and the tools they use. Interoperability is vital for optimizing collaboration between groups and stages and for maximizing the potential for a product’s ultimate success.
