Autodesk 2009 Product Lineup, Part 2
11 Mar, 2008 By: Robert GreenUpdates to the Revit product line and Inventor focus attention on new 3D design tools.
In the last installment of CAD Manager's Newsletter, I discussed new AutoCAD product news that was unveiled at Autodesk's February press event. Since almost all CAD managers have some degree of interaction with AutoCAD-based products, I figured covering those products first made the most sense for the greatest number of CAD managers.
In this installment I'll share information I gained about the other products Autodesk offers and share my insight on the changes implemented and where Autodesk is trying to position these products. Here goes.
It's the Model that Matters
Throughout the presentations and Q&A sessions I attended, I heard a repeating theme: Model your designs, don't draw them. This advice always was followed by the mantra: Using digital prototypes lets you experience your design before you build it. While most CAD managers have some degree of experience with 3D design tools, it is evident from my past CAD manager surveys that less than half of the CAD users in the English-speaking world actually use 3D design tools to any extent.
It became evident to me that Autodesk is aware that 3D hasn't been totally adopted and that an evangelistic approach to spreading the good word of 3D design would be the order of the day. I endeavored to sort the products out from the marketing and see what emerged.
Revit Architectural and Revit MEP
I've actually seen more movement to Building Information Modeling (BIM) in the last six months than in all my time in the CAD industry. Autodesk's BIM program, Revit, has been capturing a large share of this newly created market, so I wanted to look at the new tools.
Revit has received an overall interface revamping with the new ViewCube and SteeringWheels zoom/pan tools. I admit that it took me a while to get used to the omnipresent ViewCube, but it is growing on me.

But perhaps the most important change to the Revit product area was the continued development of Revit MEP to allow modeling of mechanical, electrical, and plumbing systems in the Revit building shell. This capability helps designers evaluate interferences and model the crucial building space above the ceiling tiles that most of us don't worry about. And new functions in Revit MEP allow for export of HVAC information in gbXML to facilitate analysis outside Revit MEP for computations to support LEED certification or energy audits. As Revit MEP has grown and evolved, it has become more of a design tool application center, which assists engineers with the calculations they need for these critical building systems while giving the spatial modeling benefits that Revit offers.

Revit Conclusions
Like the new AutoCAD 2009 products, the interface and feature changes in the new Revit versions will keep users on their toes. CAD managers will certainly receive some questions. All in all, I see the major benefit of the new Revit technology as the ability to tie together the various design tools that architects and engineers need to design buildings. That's where the CAD manager will be busy.

Inventor
Inventor is AutoCAD's high-end mechanical modeling and analysis tool, and it continues to become more so. The changes to Inventor are more evolutionary, rather than revolutionary, as Inventor becomes more able to handle the pesky tasks that machinery and product design engineers have to deal with.
The new release of Inventor implements a demand loaded type of assembly manipulation that allows it to handle more and more complex assemblies. And within those assemblies the parts can comprise more and more complex surfaces and geometry that would have choked Inventor just a few releases ago. And as the parts start fitting together, you can now interlink the parts with flexible and hard piping/tubing that reacts to the fittings as components in the assembly move.

The last several releases of Inventor Professional have paid more attention to the integration of electrical components into mechanical design — key for industrial machinery. Inventor's new release takes it a bit further by allowing importation of electrical harness data. All in all, Inventor is attacking the electrical part of electro-mechanical design more aggressively, which is great news for those of us who design this type of machinery.
Finally, the graphical representation of what you design continues to become more realistic and more persuasive for use in design reviews and customer demonstrations. Even those of us who learned machinery design on a drafting board have to admit that the visualization tools in Inventor (and most 3D design tools in use now) really do allow us to visualize our designs much more easily than in the past.
Inventor Conclusions
I think most existing Inventor users will be able to use Inventor 2009 without much acclimation. If they want to use the new features, they'll need to be educated on those. However, they should be able to do the tasks they're already used to with very few adjustments. I'm really not that concerned about the user reaction to the new Inventor release as a result.

What Wasn't Said
During its press event Autodesk spent a lot of time talking about the technology benefits of using fully 3D methods (fewer fit errors, easier evaluations of colors and design schemes, analysis of mechanical components) yet very little time talking about the pain points (new file formats, beefier hardware requirements, new software to learn) that come along with the change.
I've found that changing software platforms wreaks havoc with your design staff and makes normally compressed project timelines seem risky because learning new software is never built into schedules. When you factor in good old human resistance to change along with management desires to get things moving immediately, the CAD manager can be squeezed into an untenable situation.
Wrapping Up
In the next CAD Manager's Newsletter, I'll discuss some 3D implementation issues and give you some hints for making the transition smoother. Until then.
