IntelliCAD is the CAD core software managed its source code and brand by IntelliCAD Technology Consortium , which is the US NPO (Non-Profit Organization). (Here and later we call "ITC".)
This software has a high compatibility of command and data with AutoCAD and is developped to offer an useful platform in place of AutoCAD. ITC don't sell IntelliCAD by themselves and the commercial member companies of ITC provide their original products with their own specification, or utilize it as their company internal use.
Now IntelliCAD is working all over the world and translated into around 17 languages, such as English, German, French, Italian, Spanish, Dutch, Russian, Chinese.
