There are multiple tiers: , nanoCAD Plus (paid, for 2D drafting), and nanoCAD Pro (paid, adding 3D modeling and BIM capabilities). This review focuses mostly on the Free version, then contrasts it with paid upgrades. Key Features | Feature | nanoCAD Free | nanoCAD Plus / Pro | |---------|--------------|--------------------| | Native .dwg support (up to 2024) | ✅ | ✅ | | Classic AutoCAD-like interface & commands | ✅ | ✅ | | 2D drafting & annotation | ✅ | ✅ | | External references (XRefs) | ❌ | ✅ | | Raster image handling | Basic | Advanced | | 3D solid modeling | ❌ | ✅ (Pro) | | BIM / IFC import | ❌ | ✅ (Pro) | | LISP, .NET, C++ API | ❌ | ✅ | | Printing & layouts | Limited | Full |
The interface can be switched between (AutoCAD-like) and classic toolbar mode. Performance is snappy even on modest hardware (runs on Windows 7/8/10/11, no macOS/Linux native version). What’s Great (Pros) ✅ Truly free for basic 2D – No watermarks, no time limits, no cloud requirement. ✅ High AutoCAD compatibility – Scripts, blocks, and drawings generally work seamlessly. ✅ Lightweight – Installer is ~300 MB; runs faster than AutoCAD on old PCs. ✅ Familiar interface – If you know AutoCAD, you can use nanoCAD immediately. ✅ Active development – Updates every few months. ✅ Good PDF import/export (in free version too). What’s Lacking (Cons) ❌ No XRefs in free version – This is a dealbreaker for many professionals who rely on external references. ❌ Windows only – No Mac or Linux version. ❌ Limited 3D – Free version has zero 3D; Pro’s 3D is still less mature than BricsCAD or AutoCAD. ❌ No mobile or web app – Desktop only. ❌ Smaller user community – Fewer tutorials, forums, or third-party plugins compared to AutoCAD or DraftSight. ❌ Print/plot quirks – Some users report difficulty with custom paper sizes and CTB/STB plot styles. Pricing (as of 2025) | Version | Price (approx) | License type | |---------|----------------|---------------| | nanoCAD Free | $0 | Perpetual, free | | nanoCAD Plus | $180 / year | Subscription | | nanoCAD Pro | $300 / year | Subscription | nanocad review
Overview nanoCAD (developed by Nanosoft) is a CAD software platform designed primarily for the Russian and former Soviet markets, but increasingly used worldwide. Its main claim to fame is offering a free version that aims for high compatibility with AutoCAD’s .dwg format, native command structure, and interface. There are multiple tiers: , nanoCAD Plus (paid,
Note: The free version is essentially a robust 2D viewer/editor, but with notable omissions like XRefs. Excellent DWG fidelity – nanoCAD opens and saves files without corrupting geometry, text styles, or dimensions. Command aliases (e.g., L for Line, C for Circle) match AutoCAD, making transition easy for experienced users. Performance is snappy even on modest hardware (runs
, the $180/year Plus version is a steal for XRef support and advanced raster tools. The Pro version is harder to recommend over BricsCAD or ZWCAD unless you specifically want a lightweight BIM workflow.
Compare to AutoCAD: ~$2,000/year. DraftSight Professional: ~$300/year.
