IDEA from 4M Solutions is a BIM application for architectural design built on top of IntelliCAD®, which is best known as the low-cost alternative to Autodesk® AutoCAD®. The development of IntelliCAD is regulated by the IntelliCAD Technology Consortium (ITC), which does not market or sell IntelliCAD itself but, instead, grants access to the source code of IntelliCAD to commercial and non-commercial members. The commercial members pay a fee to join the ITC and can develop and sell commercial versions of IntelliCAD, while non-commercial members can freely use the IntelliCAD source code for internal or academic use. All members are required to submit the fixes and improvements that they make to the product back to the consortium. Thus the development of IntelliCAD is distributed across developers from different organizations, making this joint effort truly unique in contrast to other strictly proprietary CAD software products developed by individual vendors. IntelliCAD is currently in version 6.6, with a beta of version 7.0 currently being tested by ITC members.There are a large number of commercial companies world-wide who are members of the ITC and supply and support retail versions of IntelliCAD. One of the leading ITC members is 4M Solutions, based in Greece; others include BRICSNET, Autodsys, Inc., CADian, ZwCAD, and many more.
