Welcome. Heavy Fish Design is a JSON-like language for designing and layout of parts for laser cutters or CNC routers. Once you get the hang of it, we think you will have fun with all of things you can do.

Highlights include:
  • easy to use offsetting (i.e. adjusting for kerf).

  • Automatic layout of parts within the size of your material.

  • Splitting across multiple files if parts do not fit within the material.

  • Full featured expression language for easy scaling of components.

  • Easy to compose your designs into reusuable custom components.

Installation

HFD is a command line tool with available binaries for mac and windows (and simple to build for anyone with golang experience). Simply download the package, and open a terminal to render your first design. The zip file contains many example designs, which are easily customizable by changing any of the parameters near the top of the .hfd file.

DOWNLOAD NOW

Open a terminal (these instructions for mac, but should be similar on windows):

$ cd ~/Downloads
$ unzip heavyfishdesign.zip
$ cd heavyfishdesign
$ ./hfd-mac render designs/xmas_tree/nadia.hfd

You may have to override the security settings (usually, just navigate to the hfd-mac file and control+click and select open then allow – after that the command line should work)

Examples

There are loads of examples available in the repo. See HERE for the various HFD files, and to see HERE for the rendered output.
