Did you know that with PTC Creo Flexible Modeling Extension (FMX) it's possible to modify design geometry anytime without having to touch the design intent? PTC Creo FMX’s direct modeling technology allows you to edit geometry regardless of whether it is independent or constrained, and provides multiple selection criteria to quickly handpick the desired geometry for editing.
Upstream process improvements. Dutch designer Nout Van Heumen uses PTC Creo FMX upstream to make real-time changes to concept models during design review sessions. Van Heumen is a freelance industrial designer who's work includes the world’s first electric motorcycle, the Orphiro, and the Artisides OIO, an electric guitar made from space-age materials with leading-edge design.
Van Heumen creates concept designs for many products and presents these to clients in review meetings. But the clients frequently request changes, perhaps wanting to move a feature or make a dimension longer or shorter, and this can be a challenge for Van Heumen.
In the past, Van Heumen made these changes by altering the design intent of the model – a process that took too long to perform in a client meeting. So he would go back to his office to make the suggested changes and typically brought many versions of the design back to the client at the next meeting a week or two later. Often, while viewing these versions, the client would have additional ideas for changes, which again required additional design modifications back at Van Heumen’s office, followed by additional meetings.
This time-consuming process was solved for Van Heumen when he discovered PTC Creo FMX. Now, he brings his laptop to design meetings and displays the model on a projector. When a customer suggests a change to the concept design, Van Heumen uses PTC Creo FMX to select the right geometry and the quickly makes the changes by overriding the design intent.
To save time, Van Heumen often changes just enough to enable to the customer to envision what the concept will look like with the change. For example, if the customer is considering making the product longer, Van Heumen might increase the length of the enclosure during the meeting without worrying about updating the internal components.
The end result is that the client is able to make decisions much faster than in the past and Van Heumen saves huge amounts of time by not having to go through the complex process of changing the design intent for multiple design alternatives and travel back and forth to the customer to present these ideas.
Downstream process improvements. KTM, a leading manufacturer of motorsports vehicles, uses PTC Creo FMX direct modeling technology downstream to make changes to different CAD data files sent by suppliers.
KTM focuses on sports-oriented motorcycles, including both production and racing bikes. The company purchases many components from suppliers who use a variety of CAD systems and typically provide the geometry for parts in neutral file formats such as IGES or STEP. These neutral files are stripped of the design intent that exists in their native file formats.
KTM engineers bring these component models into the assembly models used to define their design. Often, they discover that they can improve the design of the motorcycle by modifying suppliers’ components. For example, the component as it currently exists might not fit a new design, but with a slight change it works perfectly. In the past, editing the neutral files would have required specifying design intent. A common workaround was to mark up the drawings with redlines or text, but these were subject to errors when interpreted by the supplier, resulting in extra work and delays.
Now, KTM engineers use PTC Creo FMX to modify the neutral files and sometimes native CAD files without having to specify the design intent. These files can then be sent to suppliers to request changes in a format that is nearly impossible to misinterpret. The modified models can also be incorporated into assembly models.
PTC Creo FMX provides an easy-to-use, fast and powerful set of geometry editing tools that enables users to make the changes they want without having to worry about the design intent.
By providing the ability to modify 3D CAD geometry without having to address the design intent, PTC Creo FMX substantially increases the efficiency of both the upstream and downstream design process.
