G-code to STL

This tool converts G-code into an STL mesh for visualization, simulation, and preprint validation. It interprets standard 2.5D toolpaths rather than exact machine behavior, producing a geometric proxy you can inspect in a 3D viewer.
Conceptually, it parses G0/G1 moves, arcs, and extrusion-like commands, builds layer slices by Z, and constructs cross-section contours that are triangulated into a mesh. Arc commands are approximated by short segments; unit handling and scaling are applied to align with your workflow.
This workflow benefits CAM engineers, CNC operators, and prototyping teams who need a quick geometry preview before printing or simulating. By generating an STL from the toolpath, you can check for tool clearance, trapped volumes, or material estimates without running a physical job.
Key differentiators include robust unit handling, adjustable mesh detail, and a direct STL export with optional ASCII or binary formats. The tool also provides mesh statistics (vertices, triangles, bounding box) to inform performance planning and downstream processing.
