IntelliCAD vs RoomSketcher

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.

RoomSketcher is floor plan and home design software for making layouts, furnishing and decorating rooms, and viewing designs in 3D. AI Convert takes a JPG, PNG, or PDF plan and turns walls, doors, and windows into editable project elements in under five seconds. FloorCapture uses LiDAR on an iPhone or iPad to capture a property and produce an editable floor plan. Outputs include 2D and 3D plans, AI renders, Live 3D walkthroughs, and 360 views. Projects are stored in the cloud and available across devices; the app also works offline and syncs again when connected. It runs on Windows, Mac, iPad, and Android tablets. Phones use the web portal and cannot draw or edit floor plans in the app. Credits cover projects, several visual outputs, AI Convert, FloorCapture, and ordered plans. A free plan is available; Pro costs $12 a month billed annually ($144 per year).
