Our software
- TurboCAD® – full 2D drafting and 3D solid modelling, from hobby projects to professional practice. Also available for Mac.

How we got here
IMSI began as a software publisher in 1983 and entered the CAD market in 1988, private-labelling the program ProDesign — now DesignCAD — under the IMSI Design name. The following year the company began reselling TurboCAD, the brand that became its flagship, and has owned and developed it since 1990.

What customers say
Works great! The price of the program is very reasonable for a 2D program, which is what I needed.

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.
