Overview

CMS IntelliCAD is a Windows desktop CAD package for architectural, civil construction, mechanical, electrical and HVAC drawing work. It is best suited to users who need broad file exchange, AutoCAD customization support or programming tools alongside drafting. Its range of license models is useful, but Mac users should account for the Windows requirement before buying.

Key features

Native DWG support is backed by DXF, DWF, DGN, PDF and image underlays, as well as SAT, DAE, SVG, IFC, RVT/RFA, STEP and IGES. This breadth is useful when work crosses drafting, BIM and 3D exchange; it is less important for someone who only needs a basic viewer. PDF underlays and batch printing also suit document-heavy workflows.

Users can bring across AutoCAD menus, fonts, scripts and symbol libraries. The programming toolkit includes Microsoft VBA 7.1, LISP, SDS, IRX/DRX and a Microsoft .NET 4.5 API, making IntelliCAD a stronger fit for teams with established custom tools or automation than for occasional drafting. Spatial's 3D ACIS Modeler is included, QuoteCAD Manufacturing is an integration, and Easy Run uses Turbo.net application streaming.

The separate ETOOLBOX Free CAD Viewer supports 2D and 3D DWG, DXF and DWF viewing on Android and Windows. It opens DWG files from device or cloud folders without requiring CAD file uploads, a useful option for reviewing drawings away from a desktop. CMS IntelliCAD also supports offline use.

Pricing

The free ETOOLBOX CAD Viewer plan is 0.00 USD per free, billed per seat, and covers 2D/3D DWG, DXF and DWF viewing on Android and Windows. It is a viewer rather than a substitute for the paid desktop CAD tools.

CMS IntelliCAD PE Easy Run costs 249.95 USD per year, billed per year. It includes an always-updated subscription, DWG/DGN, 2D/3D surface tools, LISP, IRX/DRX, SDS, VBA 7.1 and .NET API support. Choose it if ongoing updates and programming support matter more than owning a perpetual standalone license.

CMS IntelliCAD PE costs 279.95 USD per once, billed per unit, for a 64-bit standalone download. It includes 2D/3D support, raster and realistic rendering, BIM IFC/Revit, AEC objects and geographic mapping. The CMS IntelliCAD PE EASY RUN Perpetual plan is 599.95 USD per once, billed per seat, with updates for life, DWG/DGN, 2D/3D surfaces, Revit support, VBA 7.1 and .NET API. That higher one-time price suits buyers seeking a perpetual Easy Run license with continuing updates. Support is free through the forum, with paid support packs also available.

Platforms

The CAD software is supported on Microsoft Windows. Although macOS appears among the platform options, running IntelliCAD on macOS through virtual 64-bit Windows requires a USB dongle license; it is not a native Mac CAD workstation. ETOOLBOX provides a separate viewer for Android and Windows.

Who it's for

IntelliCAD is a sensible choice for Windows users doing professional drafting across the listed disciplines, especially when DWG compatibility, exchange formats, AutoCAD customizations or code reuse are priorities. Buyers should compare the included tools and license terms against their workflow: the free plan is for viewing, while the paid plans target CAD creation. It is a poor fit for anyone who needs a native macOS CAD application.

Pros and cons

Pro: Native DWG plus a wide range of exchange formats can reduce friction when collaborators use different CAD and BIM tools.
Pro: AutoCAD customization transfer and multiple programming APIs give teams a path to carry existing tools into their workflow.
Pro: Perpetual and subscription licensing provide different ways to pay, and the free viewer covers basic 2D/3D drawing review.
Con: The CAD application runs on Windows; Mac users need virtual 64-bit Windows and a USB dongle license.
Con: The free option is a viewer, not the full CAD package, so drawing and programming workflows require a paid plan.

Alternatives

2D CAD Software is a useful category comparison for readers still weighing drafting tools. Choose RoomSketcher instead if your priority is floor plans and 3D snapshots, with a free plan that starts with two credits. ProfiCAD is an alternative with a 30-day full-feature trial and a free home license. For free browser-based 2D CAD with drawings saved locally, consider LiberoDraft; it requires registration to unlock the start link. LibreCAD is a free, open-source 2D CAD option with no subscription or license costs. QElectroTech is a free GNU/GPL alternative. AutoCAD is worth considering if you want the original AutoCAD product and its listed mobile, web and desktop platforms. Floorplanner is a freemium web option with up to five free projects, though free exports are SD and watermarked. GstarCAD is another paid CAD alternative with Standard and Professional perpetual licenses.

Verdict

Choose CMS IntelliCAD if you need Windows-based CAD with native DWG, broad file compatibility and the option to reuse AutoCAD customizations or programming tools. Its varied license models are another advantage. Look elsewhere if you need native macOS CAD or a full-featured free drafting application.
