What IntelliCAD is
IntelliCAD is commercial 2D/3D CAD software and a platform for developing CAD solutions. The IntelliCAD Technology Consortium licenses it to commercial members, who market and support products for architects, designers, engineers, surveyors and other CAD users. The platform reads and writes native DWG files, with compatibility described for releases 2.6 through 2020, and supports DXF files and PDF underlays. Developers can use LISP, DCL, VBA, COM, .NET and C++ extensions. IntelliCAD 15 adds Drawing Compare, AI feature previews and a modernized LISP API. For supported versions, the AI preview can connect with Claude, Google Antigravity or ChatGPT to query drawings and run generated LISP code. BIM tools attach IFC, Revit RVT and Revit RFA files as underlays and access model data. IntelliCAD 15 requires 64-bit Windows 10 or Windows 11; its Mobile Viewer is available for Windows desktop and Android. End-user support comes from the selling commercial member.
