3D CAD Converter
3D CAD Converter is Windows software for viewing and converting 3D models.
What 3D CAD Converter is
3D CAD Converter is Windows software for viewing and converting 3D models. It supports STEP, IGES, STL, OBJ, and more than 15 other formats, with batch processing for complete folders, file-naming templates, and mirrored folder structures. Before meshing, it can repair broken STEP, IGES, and BREP surfaces. Adjustable tessellation controls and quality presets shape mesh output. Its GPU-accelerated viewer provides wireframe, solid, and X-ray modes, measurement tools, and assembly inspection. A command-line interface offers watch-folder operation, profiles, JSON output, and exit codes for CI/CD workflows. An included MCP server allows AI agents including Claude, Claude Code, Cursor, Codex, and VS Code to interact with local CAD files. The maker says processing is local, personal data is not collected, and the app works offline after setup. Setup needs internet unless using the full offline installer. It targets 3D printing, CNC, manufacturing, CAD exchange, web and real-time 3D, and archival work.
