First, there are many applications that cannot benefit from 3D, for example, schematics. Secondly, there is a basic tradeoff to be made before jumping into 3D. What types of work does the user do? What are the benefits of 3D for that type of work? And what are the costs to get there and to perform the work in 3D? Let’s look at a few examples:

Store or distribution center layout comes to mind. The store is built and the walls are up. Now it is time for the merchandisers to decide where to put which department, where to locate the display devices, how traffic will flow and the like. This has always been done in 2D for good reason. It is quicker, easier, more suited to the type of people who do the work, and it works! While it might be interesting to be able to “walk through” a 3D model of the store, does that benefit outweigh the cost? Usually not. It is way more important to have a great, accurate library of symbols to be quickly grabbed and placed precisely on the 2D layout.

01 - Tom Lazear would argue that in many cases such as working drawing level documentation for landscape design, there is little value in 3D over 2D CAD.

How about sports complexes? Sagamore Publishers’ classic book, “Facilities Planning for Health, Fitness and Sports,” edited by Thomas Sawyer, is a good example. They include a copy of VersaCAD 2D with each book knowing that 2D is all that is required to layout a new badminton court. Mechanical part and assembly design was one of the earliest applications to go to 3D. And with software like Solid Edge or SolidWorks, 3D is good. However, there are still simpler applications where 2D can do the job just fine, such as parts that are manufactured by 2.5D including flat parts with holes, flat parts with cutouts and more.

Civil always works in what looks like 2D, but is actually backed by 3D models. Architecture has been a favorite target for 3D or BIM software. It just seems logical that a building which is naturally a 3D object should be designed in 3D. And, of course, all buildings are and always have been designed in 3D. The question is whether the design should continue to be in the mind of the architect or on the computer. The next question is how to display the design in a fashion that is easily understood, economically prepared and satisfactory for building from.

02 - A sample VersaCAD produced architectural elevation at working drawing level.

There is an argument that , for simpler buildings, experienced architects can move more quickly using their collection of information such as standard details, previous projects, catalogs and the like, than they can putting all of that information into a computer. Here again, there are complex, multi-designer projects where the overhead work of dealing with the computer can pay off large benefits when everyone works off a common 3D model. But that argument does not apply for a number of simpler, smaller architectural projects.  Certainly, if industry standards are enforced which requires all buildings must be done in 3D, then the architect has no choice but to adapt or run the risk of not being awarded projects.

So the bottom line is the user needs to make a business decision based on facts and not marketing hype. Here is a short outline on how that analysis might be performed:

Investment Necessary

Benefits to be Derived

• If GSA (or other dictated) – have to do it
• If multi-designer – better coordination
• If owner accepts idea – fewer change-orders
• Earlier – more accurate estimates
• If done right – maybe more satisfied customers

What is above is just an outline. Your own analysis will add detail and other bullet points. When you look closely at what is the true return-on-investment for moving from 2D CAD to 3D CAD/BIM you may be surprised. The point is, to do an honest analysis with no preconceived notions of where you want to arrive. If the rate of return is high, then by all means make the investment to move to a 3D BIM model. If on the other hand the return on investment is not there, then continue to stick with 2D CAD. The benefits of that strategy are typically–again an outline:

• Easier to find capable employees
• Less costly hardware necessary for 2D CAD
• Much less costly 2D CAD software
• Less costly employees
• Think about the project and less about the complex computer software

The bottom line is: there is a case for 2D CAD in a 3D BIM world. While the industry is currently in transition, this means that part of the world benefits more from 2D and part of it benefits more from 3D. You have to evaluate yourself and your business and learn what side best still serves you. 

If you do stick with 2D CAD, there are several excellent choices on the Mac (and Windows). If you do stick wtih 2D CAD, VersaCAD for Mac is an excellent choice!

OpenGL support added to REALBasic

REAL Software has released its new REALBasic and REAL Studio version 3 products. There are more than 100 improvements and 31 new features including, among other great things, OpenGL support for faster creation of 3D applications compared to traditional C-programming methods. 

The software is used to create programs for Mac, Windows and Linux operating systems, using both BASIC computing languages and visually-designed interfaces. The new OpenGLSurface control does require a knowledge of the OpenGL language. However, there are some open source projects that are implementing a RB3D-compatible API on top of the OpenGL for developers who currently use RB3D. 

REAL Software recently published an Introduction to REALbasic video on YouTube.com. 

VersaCAD update coming soon! Focus on Translators

The latest Archway newsletter mentions an upcoming VersaCAD update that will focus on updating its CAD translators, especially on the Mac. The Windows version will get faster and will now support multiple instances. VersaCAD will now have a different and better database engine behind it, paving the way for innovative future upgrades.

Tuned for Vista

VersaCAD 2008 for Windows is tuned to run well on Microsoft’s latest OS, Windows Vista, while maintaining compatibility with Windows XP and Windows 2000. Today VersaCAD 2008 has a tiny footprint for a full-featured CAD application when compared to rivals on the market, enabling it to run on computers with less memory.

VersaCAD 2008 has much improved AutoCAD file support and utilizes the latest API libraries from the Open Design Alliance, including support for AutoCAD 2007, 2008 and 2009. New features also include a Recent Files submenu under the File menu, new Bill of Materials (BOM) menu item, support for nested symbols, improved snap grid, 100 new built-in fonts and a completely new organization of symbol libraries by discipline. All such changes, including XML file format still preserve the API for applications so no existing applications require changes. VersaCAD 2008 still preserves “single keyboard command entry” which yields a short learning curve for a full-featured CAD package. 

Pricing

Single seats of VersaCAD 2008 for Windows are $795.USD and $195.USD for academic use. Existing subscribers will be sent a new license when the product ships, which means essentially now. Perhaps VersaCAD 2008’s best value is its unlimited corporate license pricing, enabling a large corporation to run VersaCAD on dozens of seats for just $3,500.USD. 

The Mac version of the latest VersaCAD 2008 is still under development.
