It should work, believe me!
Here a bit more code, which shows what I mean -

#declare Norm = <0,0,0>;
#declare loc = trace (M1, start, <0,0,0>, Norm);
#if (vlength(Norm) != 0)
        object {
                eye
                rotate <degrees (atan2 (Norm.z,Norm.y)),0,-degrees (atan2
(Norm.x,Norm.y))>
                translate loc
        }
#end

If the difficulties persist, please post the relevant code part.
