Inkstitch is an extension / add on for Inkscape, which converts vector drawings to embroidery files.
Turtlestitch has the ability to export drawings in SVG (Scalable Vector Graphics) which is the native format for Inkscape. It is not uncommon to make a Turtlestitch drawing that is too large for the embroidery machine to use, but Inkscape can be used to scale such drawings and then Inkstitch can make a file that can be used.
