IntelliCAD is the intelligent choice for architects, engineers, designers.
Edit by : IntelliCAD?is the intelligent choice for architects, engineers, designers - virtually any professional who creates or uses CAD drawings.

IntelliCADs native file format is .DWG, so when you open an existing DWG file theres no file conversion and no data loss. We provide industry standard compatibility with an AutoCAD command set, as well programming apis such as LISP and SDS (IntelliCADs C programming API). That means you can get to work immediately using the DWG files, commands and applications you rely on.

IntelliCAD offers many unique productivity features, including the ability to open multiple drawings at once; a Drawing Explorer that lets you Review and exchange drawing content with drag-and-drop ease; and visual customization of menus and toolbars -- no programming required! And thanks to its ActiveX integration, you can insert IntelliCAD drawings (or just parts of them) into a Microsoft Office application file such as Word or Excel.

For the first time ever, you can buy a heavy-duty CAD program thats compatible with the .DWG file format and industry standard applications at mass-market pricing. Other feature-rich, low-cost CAD programs have tried to Create their own standard as opposed to leveraging the existing .DWG standard. IntelliCADs low price makes it affordable to anyone who creates and uses .DWG files.

If you have existing applications that were built using the ADS or AutoLISP libraries, you can quickly port them to IntelliCAD, using the same languages and functions you are used to. IntelliCAD also includes a VB object model to implement custom programs quickly within your organization.
