How to Make a Cruise Missile

### Step 1: The Wings

In an analog way to the "wings" at the "Torpedo" we buildt the wings here with a scaled and sheered cone. We use a macro to keep the design more flexible. The variables are the wing base radius "Wing_Radius1", the wing end radius "Wing_Radius2", the wing length "Wing_Height" and the sheering factor of the wings "Wing_Sheer".

The "Wing macro":

 ```#macro Wing(Wing_Radius1, Wing_Radius2, Wing_Height, Wing_Sheer) cone { <0,0,0>,Wing_Radius1, <0,Wing_Height,0>, Wing_Radius2 scale <1,1,0.1> matrix< 1, 0, 0, -Wing_Sheer, 1, 0, 0, 0, 1, 0, 0, 0> } // end of cone ----------- #end //------------- end of macro ```

### Step 2: The Body

In the same way like the "Torpedo" we buildt the body by two ellipsoids (red) and a cylinder (yellow) all with the same radius. This time we use a macro to stay more flexible. The variables are the missile radius "M_Radius", the length of the missile "M_Len", the width of the wings "Wing_Width" and the scale used for the tail "Tail_Scale".

 ```#macro Missile (M_Radius, M_Len, M_Wing_Width, Tail_Scale) union{ sphere { <0,0,0>,M_Radius scale<1.5,1,1> } // end of sphere --------------- cylinder{<-(M_Len-Tail_Scale*M_Radius),0,0>,<0,0,0>,M_Radius  } // end of cylinder --------------- sphere { <0,0,0>,M_Radius scale translate<-(M_Len-Tail_Scale*M_Radius),0,0> } // end of sphere ---------------- // the wings object{ Wing(0.75,0.25,2.0,0.35) translate<-M_Len+0.8,0,0>} object{ Wing(1.0,0.4,3.5,0.25) rotate < 85,0,0> translate<-M_Len*0.7,-M_Radius/2,0>} object{ Wing(1.0,0.4,3.5,0.25) rotate <-85,0,0> translate<-M_Len*0.7,-M_Radius/2,0>} // the engines torus{ 0.8,0.5 rotate<0,0,90> scale<7,1,1>*0.25 rotate<0,3,3> translate<-M_Len*0.85,M_Radius*0.95,-M_Radius/2> } // end of torus --------- torus{ 0.8,0.5 rotate<0,0,90> scale<8,1,1>*0.25 rotate<0,3,3> translate<-M_Len*0.85,M_Radius*0.95,-M_Radius/2> scale<1,1,-1> } // end of torus ---------- }// end of union #end //-------- end of missile macro ```
