3D Modeling

Improving CAD to Solver Process with 3D Precise Mesh

In much the same way as physical design has moved from paper 2D drawings to 3D models in software, so has analysis. Designers and manufacturers are rapidly moving away from physical models to perform analyses, such as structural integrity or airflow, in order to shorten design and optimization time, while dramatically improving both the performance and costs of their results.  The processes used for analyses require that the model be discretized into approximations, so that the mathematic equations can be solved at an appropriate scale.

Healing and Preserving 3D Model Intent

Part and parcel with model-based engineering is model translation. Because the model is now the specification, accurate translation from one system to another becomes essential. But even if a model is accurately read, the intent of the model has to also be properly interpreted. Key to proper model interpretation is healing — the process of modifying model data so that it conforms to the rules of the target system, while adhering to the intent of the source.

Rapid 2016 – 3D Printing & Additive Manufacturing Event

On May 15-19, the Society of Manufacturing Engineers held their annual RAPID event — the longest-running, additive manufacturing conference in North America. I attended the show last year, so I was surprised at how much the focus of the show had changed.

Whither 3D Modeling

The term disruptive technology is often overused (and typically just marketing hype), but there are some technologies that evolve over time, having an ever increasing impact on our lives. 3D Modeling is one such technology, often unseen by the public, but changing the way products and systems are designed. Some industries such as aviation could not dream of returning to a world of 2D drawings. But other industries have been slower to adopt the technology, or have limited its rollout.

Premier 2016 3D Modeling Event

This week we released the details for the 3D Insiders’ Summit 2016 and opened registration for the September 28th to 29th event. While this event may not have the cachet of the Oscars or Burning Man (certainly doesn’t have the same dress code), this a significant event in the world of 3D modeling. This is a chance for you to receive hands-on technical training, learn about new features, and meet one-on-one with our technical experts at the Broomfield, Colorado venue.

Does Lisp Influence Your C++?

The idea for this post started on Aug 11, 2011, when I read Gregg’s post about choosing a scripting language for 3DScript, the CGM interactive test bed.  That article had a lot of good ideas, but I feel like it kind of missed the point regarding Lisp/Scheme/Functional Programming.  He used a do loop to try to make the point that the syntax is rather goofy.   The reason scheme came up at all is that it is used as a scripting language for acis3dt.exe o

What You Don't Know You Don't Know

Debugging problems is really easy once you "have them under glass". Get all the input data, get all the code, build it on your computer, and you can bisect down on the problem in the debugger until you have fixed it. (Ok. This is an over simplification. Assume that you are really smart, can talk to someone who knows about the code you are looking at, and have an unlimited supply of time and coffee :-).)

The Trouble with Namespaces

Today, I’m going to talk about the way my attitude towards using namespaces has pretty much done a complete reversal over the last couple of years.  I started off thinking that they looked great, progressed to mild concern that they seemed to be causing unexpected difficulties, and eventually realized that they can become unmanageable if allowed to grow out of control.  Just like a bunch of tribbles. (Yes, the title is a Star Trek reference :).

3D Modeling in Popular Culture

Did anyone else notice in Prometheus (recent movie), that when they landed on the planet of the crazy space men, the ship's captain used something suspiciously like a laser scanner to get a 3D point cloud which mapped the tunnels in the alien city?

I thought that was really cool. Scanners like that actually exist today. (They are not the size of a golf ball, like the scanner in the movie was, but the principal is the same.)
