Design World: Parametric or Direct Modeling, One or the Other, or Both?

By ADMIN | Published: FEB 16, 2012

Design World publishes a paper by PTC’s VP of Product Management, Brian Thompson, on the features and benefits of parametric and direct modeling CAD solutions:

There are a few differences between parametric and direct modeling. The parametric paradigm provides an “engineer it” approach to design which requires you to anticipate and define feature constraints, relations, and dependencies to ensure that any design modification will update all related downstream geometry in a predefined way.

Direct modeling, on the other hand, provides a “just do it” modeling strategy that gives you the power to quickly define and capture geometry. You focus on creating geometry rather than building features, constraints, and design intent into your models.

In one minute or so: How is Creo different from other vendors’ offerings?

It seems like every vendor offers a direct modeling option with their parametric solutions. In this group of video responses to your most frequently asked questions, Mike Campbell, Divisional Vice President of Creo Product Development, explains how we serve the non-parametric user as well. We’ve summarized his answers in just a few words (for you skimmers), but you’ll want to view the complete videos for details.

 Q. How does Creo compare to products from other vendors who offers multiple CAD approaches?
“We serve the non-parametric user as well as the parametric user. We have solutions for those who are overserved by parametric modelers.”


Q. Will I need to install every Creo 1.0 app?
“Each app is standalone.”


Q. Is the Creo 1.0 UI new?
“Yes.”

Design News: PTC’s Direct Modeling Strategy

“What’s important about this 18.0 release is that we’ve made tighter integration for our legacy customers so they can continue using the core engineering system, but still benefit from the other Creo Apps, like advanced FEA tools,” says Teague. “Data can now move back and forth … and we’re creating a process that enables both direct and parametric modeling whereas before they were separate tools.” To create this tighter integration, PTC leveraged its Granite kernel so solids can be sent back and forth between the two systems.”

Creo Customers: World Records, Microsoft Kinect, and Creo

How Creo helped Microsoft’s Kinect for Xbox 360 become the world’s fastest-selling consumer electronics device ever.

 

“Officially named the fastest-selling consumer electronics device ever by Guinness World Records, Kinect for Xbox 360 has gone down in history as one of the greatest successes in the gaming sector. The first of its kind on the market, the controller-free entertainment system sold an average of 133,333 units per day to total eight million units in its first 60 days between 4 November 2010 and 3 January 2011 – a figure no other consumer electronics device has exceeded within this time span.. Rebecca Lambert takes a look at how the use of PTC technology has helped make Microsoft Kinect the success it is today.

 ‘The incredible speed and flexibility of direct modelling has enabled us to achieve results that would not have been possible with a parametric approach. Each method has unique advantages, so the blending of these capabilities in Creo enables users to access the extended capabilities of both. The result is a toolset that is powerful, flexible and very fast.’ Louis Barinaga, director of mechanical engineering, Xbox Accessories.”
