Replacements
Listings that take over the same core job as ZWCAD.
AutoCAD
Autodesk's 2D drafting and 3D CAD application, available on the desktop and in the browser.
AutoCAD is Autodesk's native DWG application for 2D drafting and 3D modelling with shared desktop and web versions, sold under subscription and requiring an Autodesk account.
BricsCAD
Native-DWG CAD software with 2D drafting, 3D modeling, BIM, and mechanical variants.
BricsCAD also works natively with DWG for 2D and 3D, adds BIM and mechanical variants, and runs on Windows, macOS and Linux after a paid licence.
GstarCAD
Commercial CAD software for 2D drafting and 3D design that works natively with DWG files.
GstarCAD is another Windows DWG-native CAD for 2D and 3D work, with separate industry editions for mechanical and architectural design and related cloud and BIM products.
progeCAD Professional
AutoCAD-compatible 2D and 3D DWG CAD software for Windows sold with a perpetual licence.
progeCAD Professional keeps an AutoCAD-style DWG workflow on Windows with a perpetual licence, and it imports Revit, IFC, STEP and PDF files.
nanoCAD
A DWG-compatible 2D drafting and 3D modelling CAD platform for Windows with optional modules.
nanoCAD offers freemium DWG-compatible CAD on Windows with modular add-ons for mechanical, construction and survey work, but it recommends fairly demanding hardware.
DraftSight
A commercial 2D CAD desktop application for drafting and editing DWG drawings, from Dassault Systèmes.
DraftSight from Dassault Systèmes offers full DWG support on Windows at a lower budget, focused mainly on 2D drafting and paid after the trial.
LibreCAD
A 2D CAD program for DXF and DWG drawings, built from the free edition of QCAD.
LibreCAD is free and open source on Windows, macOS and Linux, reading DWG and writing DXF and DWG, but it handles 2D drawing only.
QCAD
A 2D CAD program for technical drawings: floor plans, mechanical parts, schematics and diagrams, with DXF and DWG in and out.
QCAD is open-source 2D CAD with DXF support on three platforms, keeping DWG support in the paid Professional edition and offering no 3D modelling.
Also worth comparing
These listings name ZWCAD as their own alternative, so the relationship runs both ways.
TurboCAD
Commercial 2D and 3D CAD software for drafting and mechanical and architectural design on Windows and Mac.
ZWCAD is paid Windows CAD with native DWG compatibility and a perpetual licence option, covering 2D drafting and 3D work but not macOS.
