In the “hardware” or physical product world of engineering, there are usually three primary silos:
These silos result in linear, iterative, and time-consuming processes. Let’s look at how we can eliminate them.
In my previous experience as an analyst, I recall numerous conversations in which a designer handed off models to an analyst, who would then laugh. “I don’t even need to mesh the model. I can tell you’re going to have problems.”
How much time could be saved if engineers could easily perform their own basic structural, modal, or thermal analyses in conjunction with the design process?
Tools like Creo Simulation Live empower users to perform their own analyses in real-time while they design. Creo Simulation Live uses ANSYS technology built into Creo Parametric and solves using your computer’s Graphics Processing Unit (GPU).
All the design needs to do is define loads and constraints and the results presented immediately. Best of all, the results update as you make changes to the model – so you effectively incorporate analysis into the design process.

By integrating analysis into design, a silo gets eliminated and designers are able to iterate more quickly and arrive at an optimal solution faster.
Breaking down the silos between design and manufacturing can significantly reduce cost and time-to-market by identifying expensive or impossible processes early.
Someone performing rudimentary machining toolpath generation could realize that a part could require an excessive number of setups and tool changes. Or they might identify deep pockets or other features that would cause tool chatter and defects – if they could be machined at all.

For plastic injection molded and cast parts, mold cavity definition could reveal that the part might have too many undercuts, or insufficient draft to allow proper release.
As for additive manufacturing, verification during design can answer questions such as:
You can eliminate these silos by having manufacturing engineers work with designers or providing designers with manufacturing modules within their CAD tool.
These silos within engineering don’t even cover the other areas in the enterprise, such as:
These domains typically don’t use CAD. To connect these domains to engineering data, we can leverage a product lifecycle management (PLM) software system like Windchill. PLM systems don’t just provide CAD data management, but also allow end users to:
One of the biggest benefits of PLM is the ability to provide visualization of CAD data across the enterprise, without installing the native CAD authoring application (like Creo Parametric) locally. People can view the data on a computer, tablet, or phone using an ordinary web browser. They can also perform measurements, view cross sections, examine mass properties, detect interference, and explode the components.
CAD and PLM can break down the barriers both within engineering, and between engineering and the rest of the enterprise. And not a minute too soon. Smart connected product design is about to add more groups to the party--think software engineers and design technologists.
What technologies and processes will you need to accommodate them all? We’ll talk about that in a future blog post.
