Part 2 of the Perceived Quality Series shows how a Monte Carlo analysis can be set up and used to determine the appearance of a product incorporating variation. Sign up for the DCS Newsletter to keep up to date on Part 3 of the Perceived Quality Series (http://www.3dcs.com/mailing-list.html): Part 1 – Spec Studies (February) Part 2 – Variation Studies (March) Part 3 – High End Visualization Tools (March) Perceived Quality has become more valuable to manufacturing as OEM’s begin to understand that the perception of their vehicles’ quality is almost as important as the quality of their vehicles. With ratings given based on Perceived Quality, and teams dedicated to its application, it is clear that Perceived Quality Studies are valuable to cutting edge manufacturers. Stop working with nominal products and see how your design will impact your product's appearance when built. Adjust the inputs based on specifications and tolerances and quickly re-run the analysis to determine the outcome. Through iterative changes, match manufacturing specifications with design objectives. Get all of DCS's Webinars On Demand at: http://community.3dcs.com/webinars
