Show HN: Aircad – Professional drafting and 3D modeling in the browser (aircad.com)

Aircad, a new web-based application for professional drafting and 3D modeling, enables users to start drawing directly in their browser without any installations. This platform combines robust 2D and 3D drafting capabilities with features like version history, multiplayer editing, and an AI-powered command agent that enhances user experience by allowing commands to be executed in natural language. With the ability to open DWG and DXF files while maintaining critical layout and dimension elements, Aircad targets efficiency in collaboration, ensuring that every edit is tracked and that users operate with the latest file version. This development is particularly significant for the AI/ML community as it exemplifies the integration of AI in design tools, streamlining workflows by merging traditional drafting techniques with modern technology. The performance capabilities are impressive, managing over 250,000 entities in a single file, which supports complex projects without performance degradation. Furthermore, for developers and users alike, the command scripting feature allows customization through JavaScript, enabling tailored functionalities that enhance the drawing experience. Aircad positions itself as a forward-thinking solution in the CAD landscape, appealing to professionals who value real-time collaboration and robust design tools in a single intuitive interface.
