Updated and Expanded for AutoCAD 2005!
Tailoring AutoCAD 2005 is the new e-book for AutoCAD 2005. Download as a 260-page e-book in PDF format (US$26.95) or on CD ($31.95). Covers all areas of customization, from changing the user interface to writing toolbar macros and LISP routines.
Back in June, Alibre was granted US patent 6,748,419 for technology that might become important in the future. The patent envisions a method of doing 3D solid modeling using multiple computers connected to each other via any sort of network. The invention has five layers of computing:
1. The user interface - what the user sees on the computer screen.
2. The design application - generates visual representations of models and formulates requests to the design server; runs on the user's computer.
3. The design server - stores the session management program, the model data (for one or more concurrent design apps), the 3D solids modeler, and 2D/3D constraints manager.
4. The repository server - stores and serves model files.
5. The administrative server - coordinates network activities (and is not unique to this patent).
The patent envisions the five layers existing on a single computer, or on multiple computers:
When several users access the same model file, the additional users receive data proxies; the repository server ensures that only one user can edit the model at a time.

Interview with Alibre CEO Greg Milliken
upFront.eZine: "Distributed computing isn't a new concept. So, then how does your patent differ from other software that seems to do the same thing?"
Greg Milliken: "Key areas of the invention's differentiation relate to its specific application to CAD and 3D modeling, and that being distributed across various client applications, design servers, and repository servers.
"In addition, also important to the invention are how various inputs, such as change requests, are managed across a distributed network. Configurations of the invention can vary greatly when you consider the number of ways one could manage various servers and data storage related to an in-process engineering design."
upFront.eZine: "Do you feel your patent may be infringed by others?"
Greg Milliken: "It is possible other software products are infringing on the patent, but for now we are not making any specific claims in that regard. We are just taking stock of the market and various products, and if we find any that do, you can be sure we will pursue it."
upFront.eZine: "The way Alibre Design operates has changed from when it was first launched, and from when your firm first applied for this patent [in 1999]. Alibre Disign now runs primarily on local computers, not over the Internet."
Greg Milliken: "Initially, when the company was launched, Alibre was all about collaboration. Over time we shored up our 3D modeling capabilities and built a sound and growing business in the mainstream 3D CAD space. I firmly believe that the collaborative aspects of our technology are visionary and strategic to the company's future.
"Collaboration via the Internet and intranets will bring the next big advancement in mechanical design, engineering, and manufacturing. It will likely take time to become mainstream, but when it does it will have a huge impact on the way products are developed, we believe -- more so than any modeling advance, like parametrics did or could.
"In the meantime, we'll just continue the good fight of growing our business and making 3D parametric CAD available to everyone. And in the process, each new sale is akin to wiring the 'last mile' of the manufacturing industry."
Autodesk University was last week, and Autodesk flew in many of the CAD media (80, by our count) from around the world (USA, Canada, England, Romania, and Korea were source countries we noticed). Herewith some of our notes and photos from the event.
The CEO of Autodesk, Carol Bartz, presented the keynote address in person this year. She pleaded for 4,400+ attendees to "embrace change," and remarked on the democratization of design by Autodesk software.
Scott Borduin, chief technology officer, showed off features that users might find in future releases of AutoCAD and Inventor -- features similar to those found in the now-discontinued Autodesk Actrix and in the still available IronCAD (and father to both, Tri-Spectives from 3D/eye).
You'll be hearing much more of AutoCAD 2006 in the months to come (due in March), but here is a brief overview of the features illustrated by Mr Borduin:
Dean Kamen was the feature guest speaker, who during his entire talk moved about on a Segway, which he invented. He spoke of the problems in developing inventions that are innovative. He described a cart invented by the Chinese hundreds of year ago: outfitted with gears, it pointed precise, straight paths through the Gobi Desert ['gobi' means 'desert' in Ural-Altaic languages]. Inventive? Yes; innovative? No. Hundreds of years earlier, the Chinese had discovered the lodestone, but didn't figure out the compass.
Las Vegas Water Works
The media attending Adesk U were invited to the Las Vegas water works facility. They build and maintain 36,000 miles (I think) of pipes in the fastest growing city of the USA. To keep track of it all, they implemented several CAD-GIS programs to automate the addition and recovery of field data.
As-built and repair data is collected by GPS systems accurate to 2 cm (1"). Even all service trucks are outfitted with a GPS; we saw a real-time map that showed the location of the trucks: green icons for those that moved in the last 30 seconds; red for those that were stopped. The administrator said he used the GPS data to prove an employee deserved his speeding ticket.
The GPS data is transmitted back to the central office, and integrated into the GIS database through routines written in AutoCAD. Software automatically adjusts plans with the as-built data. As much as possible is done with AutoCAD, because CAD operators are cheaper to employ than GIS operators.

Letters to the Editor
"I've yet to encounter a single user that runs AutoCAD without an application. Then again, I'm a software developer, so most users that I meet at least use something that I wrote. Compared to AutoCAD, most platforms only provide second class APIs. Leaving AutoCAD means leaving their productivity tools.
"Getting LT users should be an easier
task, since there's no official API. The price in Europe is higher
than in the US; it's about US$1,700 here in Sweden, the amazon.co.uk
price is about US$1,480."
The editor replies, "Autodesk says 70-80% of customers customize AutoCAD in some way."
