CNC Code Viewer is a G-code editing and simulation tool designed for CNC programmers, process engineers, and shop floor operators. It supports mainstream CNC formats such as .nc/.cnc/.tap/.gcode and automatically recognizes file encoding, preserving the original character set during reading and saving.\n\nCore Capabilities:\n* **Visual Simulation:** Built-in 2D and 3D trajectory views, color-coded by trajectory type, displaying real-time feed, rapid traverse, tool position, and statistical data for easy inspection of machining paths.\n* **Enhanced Editing:** Integrated line numbers, syntax highlighting, find/replace, cut/copy/paste, undo/redo, font scaling, and night mode, suitable for reviewing complex programs over extended periods.\n* **Program Structure Analysis:** Automatically extracts key sections such as G00/G01, cycle machining, and tool changes, generating outline lists. Users can filter by type and jump to line numbers with one click, accelerating the location of critical instructions.\n* **Measurement and Annotation:** Supports trajectory distance measurement, envelope calculation, risk warnings, tool table viewing, and custom annotations to aid in on-site communication.\n\nMulti-format export: Simulation screenshots and statistical information can be exported as PNG/SVG/PDF/CSV for easy reporting and archiving.\n\nOverall, CNC Code Viewer integrates editing, debugging, analysis, and display into a single interface, making the process of writing and verifying CNC programs more intuitive and efficient.
