You won't get them any better than that using this method without getting deeper into it like Silviski mentioned .!. . . .or drawing them from scratch.
BUT I don't see the problem here.? Get your basic shape imported then tweak the error out in CAD. It's a one time deal after that intial first import and tweak you have perfect templates.
You don't need to waste material for the intial test just put felt tip pencil in the spindle and draw out the shape and compare against your original template. You see the error and it takes 5mins to correct and away you go perfect parts every time.!!
