In their own words
IntelliCAD
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.
QCAD Professional
QCAD Professional is 2D CAD software for technical drawings such as building plans, mechanical parts, and diagrams. It runs on Linux, macOS, and Windows. Drawing tools include layers, blocks, construction and modification commands, object snaps, measuring, and scaled multipage printing. The Professional edition reads and writes DWG and DXF through version R32, covering 2018–2026, and supports PDF, SVG, bitmap, DWF, and DGN formats. Its Library Browser offers more than 5,000 CAD parts as free add-ons. An ECMAScript (JavaScript) interface supports creating and modifying entities and building interactive CAD tools. Command-line utilities batch-convert drawings to PDF, SVG, bitmaps, and other formats. QCAD offers Professional trial packages and a free, open-source Community Edition. The single-user perpetual license can be installed on multiple computers and operating systems for one user, with new-version updates included for one year. The download plan costs 48.00 USD once.
