AutoCAD vs IntelliCAD

AutoCAD is software for precise 2D and 3D drafting, design, and modeling. It uses DWG as its primary file format and also supports DXF and PDF underlays. Seven specialized toolsets address architecture, mechanical, MEP, electrical, plant, mapping, and raster design. Teams can share DWG files, work in parallel, and add markups with multiple users. AI capabilities include markup assistance, block replacement suggestions, and contextual productivity tips. Standalone subscriptions include Forma Data Management Essentials. AutoCAD runs on Windows, macOS, web, iOS, and Android; subscriptions include web and mobile access. Each subscription is assigned to one named user and can be installed on up to three devices, with use limited to one device at a time. A 15-day free trial is available. Pricing starts at $175 per month; listed options are $260 per month or $2,095 per year. Eligible students and educators can receive renewable one-year access while eligible.

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.
