Universal 2D & 3D Parametric CAD for Digital Manufacturing, CNC & Engineering

CadFold (cadfold.com) is a universal parametric CAD and digital fabrication platform built for mechanical engineers, CNC machinists, laser operators, 3D printing makers, sheet metal fabricators, digital craft & embroidery studios, and packaging designers who need accurate, production-ready CAD geometry without expensive desktop software or login walls.

Our 5-Point Pre-Flight Topological Verification Standard

Every parametric studio and ready-to-make template on CadFold is evaluated by our automated geometry verifier before export:

1. 1. Closed Outer Contour & Manifold Geometry Verification (Tolerance ≤ 0.001 mm): Ensures all cutting paths and profiles form continuous, watertight loops so CNC routers, laser cutters, and CAM slicers never stall on open vertices.
2. 2. Zero Collinear Duplicate Line Guarantee: Eliminates overlapping toolpath segments that cause double-burning, material charring, or redundant machine passes.
3. 3. Physical Material & Tool Allowance Sanity Check: Validates material thickness (T), tool kerf/cutter offsets (±K/2), mechanical clearances, and DIN 6935 bend reliefs against physical geometric bounds.
4. 4. Standardized Multi-Layer Segregation: Separates CUT, CREASE / BEND, ETCH / SCORE, and DIMENSIONS into named CAD layers.
5. 5. True Millimeter & Inch Unit Calibration: Embeds explicit $INSUNITS = 4 metric headers in AutoCAD DXF files, physical mm viewBoxes in SVG files, and a physical 50.0mm calibration scale bar in PDF files.

100% Client-Side Privacy & Commercial Manufacturing License

All custom dimensions entered into our parametric studios are calculated directly inside your web browser using our client-side TypeScript geometry kernel. Your proprietary part dimensions never leave your device. Furthermore, all generated and downloaded CAD files (.DXF, .SVG, .PDF, and upcoming 3D/stitch formats) are 100% free for both personal and commercial manufacturing.
