Digital Sketching and the Engineering Notebook

You didn’t think we were done talking about engineering notebooks, did you? In all seriousness, I have talked about this subject a couple times fairly recently. In a post titled The Forlorn Engineering Notebook, I wrote about the fact that technology had essentially left the engineering notebook behind. Then in a post titled Digital Notebooks …

The Long and Winding Road of 3D Visualization

I will never forget my first exposure to 3D visualization. It was back in 1996 or so. I was assisting on the development of a Crew Return Vehicle (CRV) program at NASA Johnson Space Center in Houston. There was an executive presentation on the progress of the program and how their new parametric feature-based CAD …

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 …

Digital Notebooks for Engineering?

A little more than a month ago, I published a post titled The Forlorn Engineering Notebook. My point in it was that while certain activities in engineering like the creation of drawings and automation of processes had seen dramatic changes in enabling technology, the engineering notebook had been pretty much ignored and forgotten. There are …

The Forlorn Engineering Notebook

I’ll never forget the first time I went to go see a real engineer work. During the summer between my sophomore and junior years in college, I worked for a technology transfer program at school. Our job was to visit various local manufacturers and assist them with their designs by applying the latest technology, which …

Low Spatial Intelligence as an Impediment to 3D CAD

If you’ve been following the engineering-matters blog for a while, you know I’ve written a good bit about CAD over the past year or so. And why not? It’s an industry that’s been re-energized by a number of big shifts in technology during that time. Several old and new software providers are trying harder than …

The Pitfalls of Multi-Disciplinary Simulations: Divergent Model Abstractions

For the past few years, most of the simulation and analysis industry has been abuzz concerning multi-disciplinary (MD) simulations, and rightly so. MD analysis offers a far more realistic view of product performance than one-off simulations. But despite the increasing availability of MD simulation capabilities, it’s not all roses. In fact, there are some serious …

CAD Standardization: Approaching An Obsolete Practice?

I remember back when I came into the industry, back in 1995, CAD standardizations ruled. OEMs at the top of design chains carried huge power in selecting a CAD application and then requiring their suppliers to deliver 3D models to them in that format. OEMs that switched their standard from one CAD application to another …

The Next Disruptive Wave for CAD Applications?

The last few years in CAD have been invigorating, haven’t they? Most recently, there’s been a scramble to get direct modeling functionality out in front of both CAD Specialists and many other roles to expand the use of 3D. And before that there was an ongoing effort by many to improve the usability of CAD software which mostly came in the form of where icons are at or how small dialog boxes can be.
