Although it is not a direct method, you can use Blender:
- File -> Import -> Scalable Vector Graphics (the resulting object is a path)
- Object Mode -> Object -> Convert -> Mesh (to get a triangulated shape)
- Object Mode -> Add Modifier -> Decimate (to reduce the number of faces when necessary)
- Edit Mode -> Face -> Tris to Quads (to convert some triangles to quadrilaterals)
- Export -> LDraw (you need to install the free extension ExportLdraw)
