LibreCAD
The premier open-source application for high-precision 2D Computer-Aided Design.
The professional-grade CAD platform with native DWG support and an open API for mission-critical engineering.
nanoCAD is a high-performance CAD platform designed as a technically superior alternative to legacy CAD solutions. Built on a native DWG core, it ensures 100% data integrity with architectural and engineering files. The 2026 iteration leverages a modular architecture, allowing users to scale from a basic 2D drafting engine to a complex 3D modeling environment using the C3D geometric kernel. For developers and AI architects, nanoCAD is notable for its 'Open API' strategy, supporting C++, C#, .NET, JavaScript, and LISP, enabling deep automation and integration with external ML models for generative design. Its performance in handling massive point clouds and complex 3D datasets positions it as a leader for infrastructure and industrial projects. Unlike competitors moving toward cloud-only models, nanoCAD maintains a flexible approach with both subscription and perpetual licensing options, catering to industries requiring offline stability and data sovereignty. The platform includes advanced raster-to-vector conversion, a powerful table editor with Excel-like functionality, and built-in support for IFC files, making it a pivotal tool in modern BIM workflows.
