About Heartline Works

Heartline Works is a design-first resource platform for makers, laser cutters, CNC users, jewelers and casting professionals. Its two main libraries are Vector / Laser / CNC designs and Jewelry / Casting / 3D designs. Professional tools and calculators and guides support them.

What we publish

• Design files in SVG, DXF, PDF and PNG for laser and CNC, and STL and OBJ for casting and 3D work. Every design currently in the library is an original Heartline Works construction, with its source and licence stated on its page.
• Guides on preparing files, kerf, formats and casting weight.
• Calculators with visible formulas, worked examples and stated limitations.

How we try to earn trust

• We say where files and data come from, and when we last checked.
• We offer a format only when a real file in that format is generated and checked. We never relabel one format as another, and we do not offer AI or CDR files we cannot generate reliably.
• Market values are labelled as reference values, with the data time. When data is unavailable we say so instead of showing an old number as current.
