A free version available for commercial use. Domestic CAD "JDesignCAD" that integrates 2D and 3D.

JDesignCAD is a domestically produced general-purpose CAD that integrates 2D drafting and direct solid modeling into a single environment. It can be used for a wide range of applications, from the design of mechanical parts, jigs, and enclosures to architectural, interior, furniture, and product design considerations. It includes features such as extrusion, rotation, sweep, loft, solid cutting with surfaces, real-time section display, and interference checking. The free version can also be used for commercial purposes, offering basic 2D and 3D functions, editing, saving, and output in JDC format, as well as STL output for 3D printers. The paid Standard version provides the ability to export to external CAD formats and includes CAE (analysis) functionality. It supports cost reduction in the introduction of design environments and improves operational efficiency for both small and large enterprises.
