CMS IntelliCAD 8.3, and following, is available in 64-bit (x64) only because x64 is about 30% faster than 32-bit. 64-bit systems are increasingly replacing 32-bit systems. The 64-bit version of IntelliCAD runs faster than 32-bit, but can use all available system memory to handle large drawing files. 32-bit applications can access up to 3GB of RAM on 32-bit operating systems and up to 4GB of RAM on 64-bit operating systems. To avoid such limitation, the CMS IntelliCAD is only available for 64-bit systems starting from 8.2 version.

CMS IntelliCAD CAD Software is now available as multi-core 64-bit application only.
