Both ZWCAD and GstarCAD are popular CAD software options developed by Chinese companies. While they share similarities and offer comparable features, they have some differences. Here's a comparison between ZWCAD and GstarCAD:

Interface and Compatibility: ZWCAD and GstarCAD have interfaces similar to AutoCAD, making them more accessible to users familiar with AutoCAD. They also support the DWG file format, allowing seamless compatibility with AutoCAD files.

Features and Functionality: Both software provide 2D drafting and 3D modelling capabilities and a range of tools and features expected in CAD software. They offer standard drafting tools, layer management, dimensioning, and object properties.

GstarCAD offers several unique features that set it apart from other CAD software options. 

Here are some notable features of GstarCAD, e.g., Rapid Distance, 
AREA TABLE, AUTO LAYER, ATTRIBUTE INCREMENT, SYMMETRIC, BREAK OBJECT, BLOCK BREAK, AutoXLS Table, TEXT INCREMENTAL COPY and more.

These unique features in GstarCAD enhance productivity, simplify design workflows, and provide flexibility for users. It's essential to evaluate these features and your specific requirements to determine if they align with your needs and can contribute to your CAD workflow.

Price and Editions: ZWCAD offers different editions to cater to different user requirements and budgets, including ZWCAD Standard, ZWCAD Professional, and ZWCAD Mechanical. GstarCAD, on the other hand, offers a light version and full editions like GstarCAD LT, GstarCAD Standard, GstarCAD Professional, and GstarCAD Mechanical. The pricing structure may include perpetual licenses or subscription plans. It's recommended to visit the GstarCAD website or contact our sales team for specific pricing details. The GstarCAD price is more competitive because it is a self-developed core instead of an open source from IntelliCAD.
