IMSI User Reviews
"TurboCAD development has been quite dedicated in following AutoCAD’s functionality and offering a bigger bang for the buck." —AEC Magazine"
"With its TurboCAD line, IMSI has been demonstrating for years that the drafting needs of many thousands of engineering and architectural professionals can be more than adequately met with software costing only a couple hundred dollars." —Joel O.
"I've used a couple of different apps for CAD and I am very surprised at how much DesignCAD 3D Max can do and still be easy to use as it is." —Roger B.
"I found TurboCAD many years ago while looking for inexpensive design software for home use. TurboCAD Deluxe fit the bill perfectly and continues to please today." —Tracy R.
"TurboCAD is a solid CAD program and is, in my opinion, one of the best values on the market. It has executed every CAD-oriented task I have attempted flawlessly. The UI is mostly straightforward. It didn't take long before I was moving around efficiently in the environment. This is a 5 star program in my world." —Richard K.
"DesignCAD is simple and stable. Have been using for years. Consider it my second language after English. Does everything I need for 2D drafting, never locks up or crashes, even in Windows." —Lowell S.
"The makers of TurboCAD have done a great job making the type of program (CAD) that I was intimidated by very easy to use. It has the power of other programs priced in the high hundreds if not thousands." —Robert M.
"I began using TurboCAD in 2002 and all these years later I still get excited when I think about using TurboCAD on a daily basis." —Don C.
"I have used at least a dozen other CAD programs, and the DesignCAD user interface is far and away the easiest to use and most versatile." —Phil H.
"I have used a number of other CAD programs and I believe TurboCAD's DWG translation is much better than average. I have even seen situations where TurboCAD salvaged drawings unopenable in AutoCAD (that were not created in TurboCAD)" —Joseph M
