Precision 1:1 Parametric CAD for Packaging, Laser Cutting & Fabrication

CadFold (cadfold.com) is an engineering CAD utility built for packaging engineers, laser cutter operators, CNC machinists, sheet metal fabricators, and product designers who need accurate, machine-ready 1:1 vector geometry without expensive enterprise CAD subscriptions or login walls.

Our 5-Point Pre-Flight Topological Verification Standard

Every parametric studio and static template on CadFold is evaluated by our automated geometry verifier before export:

1. 1. Closed Outer Contour Verification (Tolerance ≤ 0.001 mm): Ensures all outer cutting paths form continuous, watertight loops so CNC routers and laser cutters never stall on open vertices.
2. 2. Zero Collinear Duplicate Line Guarantee: Eliminates overlapping cut segments that cause double-burning, wood charring, or double knife strikes.
3. 3. Physical Allowance Sanity Check: Validates material thickness (T), rollover bridges (2T + 0.5mm), laser kerf offsets (±K/2), and DIN 6935 bend reliefs against physical geometric bounds.
4. 4. Standardized Layer Segregation: Separates CUT, CREASE, SCORE, and DIMENSIONS into named DXF and SVG layers.
5. 5. Explicit 1:1 Millimeter Unit Headers: Embeds $INSUNITS = 4 in AutoCAD DXF files, physical mm viewBoxes in SVG files, and a physical 50.0mm calibration ruler 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 product dimensions never leave your device. Furthermore, all generated and downloaded .DXF, .SVG, and .PDF files are 100% free for both personal and commercial physical manufacturing.
