Do Engineers Use CAD? It’s Still a Major Debate

Do you browse LinkedIn? No seriously. I know that many years ago, LinkedIn was basically a place to post your online resume. But a couple years ago, they came out with professional groups where folks could discuss career and other work topics. Then they came out with a more newspaper-like view of your connections’ updates. Now it’s fairly easy to traverse and read good articles. Anyway, the other day I was looking through some articles in my connections’ and groups’ feeds when I came across one that resonated with me. Its title is… Engineers as Draftsman, my how times have changed… in the Mechanical Design Forum. Here’s a original post.

The Success of Spaceclaim: An Tale of Granularity for CAD?

Remember when Direct Modeling was rare. Seriously, more than five years ago, the modeling approach was pretty much relegated to being delivered to market by much smaller software providers. I’ll never forget a conversation I had with a head of product management at one of the largest CAD software providers. “That war was fought, and feature-based modeling won a long time ago”, he had said to me.

Where the Interoperability Movement Falls Flat

Ah, interoperability. A lot of changed over the course of the last few years. The CAD industry has become reinvigorated. 3D visualization seems to have become more focused on applications as opposed to just cool technology. PLM systems have started to become mainstream while more granular systems have simultaneously emerged. And despite all that change, at least one thing has been very consistent.

The Disconnect between Traditional CAD and Design

In the past three years, we’ve seen more dramatic change to the CAD industry that we’ve seen in the prior ten. Direct modeling has taken hold in many mainstream CAD applications. There has been an admission that 2D is a valid form of design and not just some laggard characteristic. There’s been a literal explosion of capabilities all related to design and engineering. All of these changes hint that there was a prior problem with how traditional CAD served users.

Altair’s OptiStruct: Functionally Driven Concept Design

Do you remember when the first simulation based optimization tools hit the industry? From what you might have read, it might have seemed as if nirvana had been found. All you have to do is define a simulation, define the design variables that should change and identify your objective and poof, the perfect design would …

Tetra4D: Leveraging the Adobe Ecosystem

What are your first thoughts when you hear the words “pdf” and “product development?” When I first heard them together, I have to admit that I wasn’t buzzing with excitement. Sure, there are lots of documents involved in product development, but I there’s nothing specific about that for engineering. My general expectation is that pdf …

Is CAD Still Disruption Ready?

Over the past year, CAD has seen some major changes. We went from incremental improvements spread across suites of CAD applications to new ways of modeling, opening up the application to potentially larger number of users. It’s definitely been interesting to see the industry reinvigorated with many new discussions and lots of passion. As I …

NX Simulation: One Model to Rule Them All

When you start looking at simulation software tools, you quickly realize that there is a lot there. There are tools for preprocessing. Tools to interrogate simulation results. There are many solvers. But one of the software tools that seems to do a lot is NX from Siemens PLM. Yes, the same NX that is also …

What Wasn’t Said at SolidWorks World 2012

A few weeks ago, I attended the spectacle that is SolidWorks World in San Diego. It was an impressive event with over 5,500 attendees. But for me, I was struck by the notable lack of news. And that’s not a bad thing necessarily. But just because there might not be any explicitly announced news coming …
