How to Make an Airplane

Adding Propeller Engines

part VII

Step 4: How to Add Simple Propeller Engines to this Airplane.

For this I'll refer to "How To Simulate a Rotating Propeller?". We have only to copy the complete definition of the macro "Engine(...)" in this scene file and then add the following to our final union:

//---------------------------------------------------------------
//#macro{ Engine(Number_of_Blades, Blade_Radius,
//               Rotation_Angle, Rotor_On)

 object{ Engine( 5, 2.35, 10, 1)
         scale 0.85
         rotate <0,-90,0>
         translate <-0.30,-0.70,-5.00>
       }

 object{ Engine( 5, 2.35, 10, 1)
         scale 0.85
         rotate <0,-90,0>  scale <1,1,-1>
         translate <-0.30,-0.70,-5.00>
         scale <1,1,-1>
       }
//---------------------------------------------------------------
