The amazing, fantabulous, bewildering world of cloud CAD: Infrastructure

"Cloud" is now a household word in today's engineering software landscape. That's both good and bad. Good in that new technology is actively being sought and aggressively adopted for CAD applications, bad in that the term places a whimsically diverse range of development, delivery, infrastructure, and virtualization technologies under one fantastically generic umbrella. So when it comes to cloud CAD, there's naturally quite a bit of consternation over whether your particular flavor of cloud-enabled CAD software might be pure, true, or perhaps even fluffy enough.

How design democratization leads to graphical commoditization

When you associate the state of CAD graphics to an alien conspiracy it just might incite a cheer, conversely perhaps a bit of rage, or in the very best case thoughtful commentary from a lagomorph well versed in computational geometry. The crux of my original article was not to convict or condemn, but rather to warn that the continually evolving CAD universe, and by association professional CAD graphics, is on the precipice of something here unto unforeseen and unimagined. It might seem like the end of all things. Something disconcerting enough that a forlorn and distraught Samwise Gamgee might longingly implore, "Don't professional graphics matter, Mr. Frodo?" For which our brave hobbit might reply: "They do Sam, they do. But not for me."

Stop whining about MBD and accurately model your products

Why is it so important for 3D data to be exact? After all, drawings on a drafting board weren't a mathematically accurate representation of designs and they got the job done just fine. Right? Well sort of. We’ve all heard the stories of someone faking in a dimension to show the right value, causing the 2D drawing to become a less accurate representation of the final product and out of sync with the 3D model (if there was one). The results of these out of sync documents usually amount to an unhappy boss.

Stop laughing at 2D CAD

It’s amazing to see where computational mechanics is heading and how different modeling techniques are constantly evolving. Not even twenty years ago, mechanical systems were drafted as plane sketches with an endless array of symbols and norms to convey as much as possible about an accurate and common three dimensional shape. Now however, we have the full 3D CAD experience ready and easy to manipulate.

Why ECC RAM matters, but probably not for most CAD design

When we put together a self-build kick-ass CAD workstation a couple weeks ago, we managed to raise a few eyebrows in our seemingly reckless disregard for random access memory. We didn’t bother to spec a system with ECC RAM, and some of you questioned why populate a CAD workstation with “the cheap stuff?” To get to the bottom of this we’re going to have to talk about billions and billions of bits, uncorrectable errors, hyperactive bananas, and supernovae. Quick, someone tweet at Neil deGrasse Tyson.

It’s Time to Get Over IGES

About five seconds into your average conversation about CAD translation, someone will invariably mention one of the venerable and long-held neutral formats: STEP or IGES. Neutral CAD formats are the great equalizers of CAD interchange; the old stand-bys of an increasingly multi-CAD world. They provide the bridge to migrate geometry from one proprietary CAD system to another. While direct translation or newer direct modeling techniques now often preempt the use of neutral formats, chances are high you'll need to rely on them at one time or another. But a word of caution: while STEP and IGES are often grouped together in the same breath, they are certainly not equivalent. In fact, if formats were horses, it's probably time to send the IGES pony to the glue factory.

Avoiding Multi-CAD Pitfalls

The broad diversity of CAD technologies available today offers more choice and capability than ever before. All that variety presents a unique problem, however. Given any moderately complex design involving different engineering disciplines, design partners, and/or suppliers, chances are you'll be wrangling multiple CAD platforms. We call it – wait for it – multi-CAD. Multi-CAD is simply a reality of design in the 21st century.
