Enventive is a pre-CAD design optimization tool that can optimize mechanical systems before CAD modeling to reduce design iterations, testing prototypes, and costs. It uses equation-based modeling to simulate parameters like forces and tolerances. This allows analysis of design tradeoffs early in the design process. Enventive has been growing rapidly and is used by over 75% of automotive companies to streamline product development.

1. Enventive
Pre - CAD Design Optimization

2. Why Pre-CAD design optimization?
• To reduce CAD modeling rework
• To reduce design iterations and increase productivity
• To analyze the effect of parameters such as forces,
friction, tolerance etc before CAD activity
• To reduce number of prototypes and reduce costs
• To make designs robust enough to accommodate
manufacturing variation

3. What is Enventive ?
• Enventive is a pre-CAD design optimization
tool that can optimize the mechanical system
design before the CAD activity.
• An equation based geometric modeling tool
• A sophisticated GD&T tool that can virtually
model any physical parameter like forces,
friction etc.
• A tolerance analysis tool that’s also an
integral part of the conceptual design
process.

5. Enventive – What it can do
• Process capabilities taken into account early in investigation.
• Export to CAD softwares
• Diverse types of complex analyses:
• Complex kinematics.
• Complex ISO tolerancing.
• Physical aspects (forces, contacts): need for DOE and prototypes
reduced.
• Structured Transfer Function optimization (focused on costs):
 Number of contributors.
 Sensitivities.
 Tolerances
 Process Capabilities
 Tolerances on small impacts contributors.
• Design reliability justification from consultation phase.
 Customer Confidence.
• Ease of use and of deployment among engineers (no full time specialist
required).

10. 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.”
Pedro Lopes – Ficosa International
