PureCutCNC
2.5D CAD/CAM workspace for designing parts, defining machining operations, previewing toolpaths and post-processing G-code.
What it does and how it connects
PureCutCNC is a browser-based 2.5D CAD/CAM workspace for designing parts, defining machining operations, previewing toolpaths, and checking the result in 3D and simulation before export. Sketching covers rectangles, circles, polygons, splines, composite profiles, text, tabs and clamps, with grid and feature snapping and direct editing. SVG and DXF import as native sketch features, and STL, OBJ and STEP models drive 3D surface machining with rough and finish passes.
Operations include pockets, contours, carving and V-carving, plus surface rough and finish for imported meshes. A standalone command-line converter turns an existing Visual Mill, Vectric/Estlcam, ArtCAM, ECam, SheetCAM, Autodesk HSM/Inventor or Mastercam post-processor file into a PureCutCNC machine definition, with a full report of exactly what was and was not carried over.
The durable product scope, supported surfaces, terminology and CNC safety contract are defined in the repo's PROJECT.md, and contributors and AI agents are pointed at INDEX.md and AGENTS.md first.
Alternatives
Compare side by side- FlatCAM Evo
A desktop 2D CAM program that turns Gerber and drill files into G-code for PCB milling, rather than a browser workspace for designing parts and machining operations.
- CADence
Parametric 3D CAD for makers that runs in the browser and as a desktop app, with no CAM operations or G-code export stated.
- SketchForge-3D
A local-first browser 3D design editor for building and cutting shapes and exporting models, with no machining operations or toolpath preview.
