What it is

IntelliCAD is commercial 2D/3D CAD software and a development platform for building 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 legal compatibility described for releases 2.6 through 2020. It also supports DXF files and PDF underlays. Developers can use LISP, DCL, VBA, COM, .NET, and C++ extensions. Version 15 adds Drawing Compare, AI feature previews, and a modernized LISP API. Supported AI previews 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. IntelliCAD 15 requires 64-bit Windows 10 or 11; the Mobile Viewer is available for Windows desktop and Android. Pricing is on request, and end-user support comes from the selling member.
