[Windell] developed an Inkscape extension called Hershey Text that helps you process fonts into vector representations. If you’ve tried to 3D print, plot, or mill text in the past you may have run across the problem of generating vector paths that deal with the outline and fill of the text appropriately. The problem stems from how fonts are defined; either by the area that they enclose, or by the path that is used to draw the outline. Check out [Windell’s] tutorial for this extension where he explains each of these issues and shows how to overcome them.
The image above illustrates the stroke options, which allow you to vector multiple paths to best fill in the correct parts of each character using path-based hardware. The package includes a wide variety of interesting font sets that are in the public domain, and includes tools such as a glyph map generator that make it very user friendly.
