3-D Rendering

Written by James Kroeker, Senior Draftsman

In today’s design world, using 3D modeling can be very beneficial. If a client is looking to build that "perfect" project, but doesn't really have much direction to go in, this is where 3D modeling can really be invaluable. With the new generation of computers, you can show a project in "virtual reality" so you can see the building design, lighting schematics, and general cosmetic appearances. It also helps to decide how to change your structure to better suit your needs, as this excerpt demonstrates:

"Suarez-Kuehne Architecture is a small firm that has discovered big benefits of using AutoCAD Architectural Desktop with 3D Studio VIZ R2.

‘Communicating design concepts to clients can be a challenge,’ said Scott Kuehne, Suarez-Kuehne principal and architect. ‘I use 3D Studio VIZ and AutoCAD Architectural Desktop together to show clients realistic spacial qualities.’

Kuehne used the software to insert alternate plumbing figures into a three-dimensional drawing for a homeowner who had difficulty weighing his options for a master bath design.

‘Using the tools together, and toggling in 2D and 3D, I quickly created a frame of reference,’ said Kuehne. ‘We could choose what worked best for the space and the client, ultimately saving time and expense. When clients can visualize spacial relationships through accurate renderings, we can keep the process moving forward without having to rethink critical design decisions later’ " ("AutoCAD Architectural Desktop," Autodesk, (1999). San Rafael, CA: Autodesk, Inc.)

I have in a short time learned how powerful this architectural software can be. I can create and render a 3D model in less time than drawing all exterior elevations of the same drawing in a typical 2D representation. The best part about it is that once I have modified the model to fit the required changes, I can take a 'snapshot' of it from any angle I choose.

I have also seen people sit down, look at a typical blueprint and get this look of "I don't understand" on their face. The general public cannot completely visualize from a 2D plan. The 3D model is a rendering of what the final product will look like when it is completed.

There are drawbacks to the software, though: the learning curve and, of course the cost. It is not at all uncommon to spend $2000.00 and up for a high-end rendering/modeling program. The good news is that there are several cheaper, less intuitive programs available, such as "Bryce 3D" by Metacreations.

The 3D software industry is changing rapidly. It is hard to identify the best package. I have used Accurender 3, and have found that the price is amazingly affordable for the power it has. It comes with a $495 price tag, but the learning curve is diminished if you are fluent in 3D modeling in AutoCAD. This by far, for the money and ease of use, is where I lay my bottom dollar. The software can create not only photo realistic images, but it also has the capability to render a walk-through, or 'fly-by' as well as a very hands-on panoramic image. A panoramic let's you actually take control of the image; you can control where you want to look simply by dragging the mouse in the direction you wish to view. The first one you see is a truly incredible experience, and one that you won't easily forget.

All in all, in today’s competitive designing industry, 3D modeling is a vital part of everyday working drawings. It is the easiest way to find possible faults, streamline your production, and 'walk-through' your creation before ever breaking ground. It is the way of the future.
