Drawing is an art, MBD is a science

Creating 2D drawings is an art – knowing what information is required and how to display it in a readable arrangement, while being efficient with the space provided, takes certain skill and experience. It used to also take a steady hand when a piece of paper and a pencil were the tools of choice. When CAD systems found their way into industry, capturing information in an electronic format was both a faster way to get the job done and provided a more consistent presentation of information.

Igniting the 3D documentation revolution – 3D PDF for the model based enterprise

Revolution? What revolution?

In 2005, Adobe® made a bold move by adding support for interactive 3D graphics within PDF files, including Acrobat® Reader®, which continues to this day. More importantly, Adobe acquired a file format that enabled 3D PDF to be adopted throughout the manufacturing industry. How that format has ignited a revolution in 3D documentation is the topic of this post.

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.

Engineering Drawings are Dead. Now What?

So that last article was rather frightening for some, you know, with the zombies and the whole thing with engineering drawings not being alive and all that. For some, it was downright traumatic. Many have rightly pointed out that cost constraints and the limitations of today's tools make Model Based Engineering (MBE) seem like an impossibly far off dream. Yet the value of evolving engineering documentation to its logical next step seems clear. So the question remains: how can we possibly get there from here? Read the rest of this entry »

Engineering Drawings are Dead

CAD has largely replaced the engineering drawing – embrace the change.

The era of hand-drawn engineering illustrations has come and gone. Yet so much of the engineering community both far and wide seem to hopelessly cling to the past. Of course, we're talking about engineering drawings. And yes, it's time for the drawing to die. But just like those pesky zombies on AMC’s hit TV show about failed team dynamics, it seems engineering drawings keep coming back to life. If we're not careful they'll eat our brains. Someone get me a shotgun. Read the rest of this entry »
