IMSI/Design Debuts First 3D DWG Viewer for iPhone

Engineers and architects alike can mobilize their designs with the free TurboViewer app, which was built from the ground up for the iOS platform.

By Cadalyst Staff

CAD software developer IMSI/Design, the maker of TurboCAD, recently announced that its TurboViewer application — released in June for the iPad — is now available for the iPhone. The free app is the first native DWG viewer that supports both 2D and 3D CAD DWG files for the iOS platform.

TurboViewer supports both 2D (left) and 3D (center) files. Users can zoom and rotate with multitouch gestures, or can tap the orange Views button to select from a list of viewing angles (right).

"We built TurboViewer from the ground up for iPad and iPhone," said Royal Farros, chairman and CEO of IMSI/Design. "We think architects, engineers, and designers are going to love having their plans in the palms of their hands."

IMSI/Design COO Bob Mayer explained to Cadalyst that several factors differentiate his company's new release from other mobile tools already on the market. "Currently, we are the only app that can view and navigate 3D DWG files natively on the iOS platform, and Android support is coming soon. AutoCAD WS, for example, only handles 2D. Read more »


IMAGINiT Tricks Tutorial: Prepare Semi-Unintelligent Parts with Suppression and Sculpt Wrapping

When Shrinkwrap doesn't provide enough control for your needs, other Autodesk Inventor tools can simplify your designs for downstream use.

By Mark Flayler

When a design is to be sent out for vendor or client use, it is often necessary to remove some design information, but also to retain critical information for the downstream users. In the end, we want a part that is easy for our clients to use, but difficult for them to have another manufacturer replicate or reverse-engineer. Sometimes this is unavoidable with your particular products, but for parts with complex core/cavity systems like hydraulics manifolds or castings, it is definitely something to strive for. A fair balance must be struck between the outside world and your engineering department on what is critical and what is not.

When Autodesk Inventor introduced Shrinkwrap in 2010, many users got the idea that this was the be-all and end-all simplification tool for this need. After looking at Shrinkwrap, however, it becomes apparent that this is an all-or-nothing scenario, where very little control is given over specific hole-patching and how much of the hole depth is patched. Also, control for removing other outside geometry is not available; Shrinkwrap simply removes interior geometry.


Once the design criteria have been examined and agreed upon, the simplification process can begin. In this example (below left), we have determined that the half-moon–shaped cut on the bottom of this part, as well as the location of two of the mounting holes (in red, below right), are too design-sensitive to be examined by third parties directly through the model.
