But you can later convert it to mesh and using plug-in called "Reduce mesh" do what it is supposed to do, that is reduce poligons if you need when you don't reduce it during converting, but it is rather silly plug-in as it's reducing abilities is... bad. That's why my tracks are simple to make my hand work reduced to minimum and to make them less resource hungry I've uploaded Alphard someday so why don't you check my poligon work
