17. Comments from Enventive Users…
“We can conceptualize design concepts ten times faster in Enventive than we can with our native CAD
system…
Rather than seeking to simply avoid problems, by using tolerance-based optimization early in the product
development process, well up-front of traditional CAD, we’re able to use Enventive to target and achieve
optimized design solutions and aggressively establish competitive product offerings.”
Yves Le Pottier – Electrical Device Supplier
“I cannot leave a discussion of Enventive without mentioning it is fun to use. The software is graphically
based. Sketches and graphical representations of the parts drive the models. This, coupled with the easy
to use interface, creates “Stack-up Junkies” who want to do the analysis because the software helps
them easily visualize the impact a design change can have on the product.”
Eric Pattok – Delphi Steering Systems
“Our engineering team has been able to use Enventive after 4 days of training. We have been able to
correct some design mistakes that were done in the past due to the limitations of the tools we were
using. In the end, our customer praised us for the speed and professionalism with which we have been
able to complete and present the DFSS phase on this project.”
