GStarCAD is based on the well-known IntelliCAD software which is the industry standard for low-cost CAD software. GStarCAD is the innovative alternative to AutoCAD that provides OpenDWG file compatibility, similar environment, as well as full support for AutoCAD commands, menus, scripts, styles, patterns etc. GStarCAD is the top quality version of IntelliCAD worldwide, 99% identical to AutoCAD and its speeds and performances with an attractive and competitive price are totally unbeatable. Unrivaled AutoCAD compatibility GStarCAD's native file format is .DWG, so when you open an existing Autodesk AutoCAD file (2.5 to 2009), there's no file conversion and no data loss. GStarCAD also provides a full compatibility with AutoCAD Command Line, menu (.MNU) and script (.SCR) files, hatches, fonts and true type fonts-Complex linetypes, Multiline Text, Lightweight polyline, Draw commands, Audit & Recover as well as AutoLISP and ADS. That means you can start to work immediately using the AutoCAD files, commands and applications you rely on. Exceptional productivity GStarCAD offers smooth Microsoft Windows integration plus many unique productivity features, including the ability to multiple open drawings (MDI) at once; a Drawing Explorer which 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 GStarCAD drawings (or just parts of them) into a Microsoft Office application file or a Visio 2000 Technical Edition schematic.
