I was unsatisfied with the first wing I did for my SketchUp aeroplane. The thing that most niggled me was the wing tip, which I couldn’t model successfully. My inability to create a nice rounded tip had me posting a request for assistance on the Google SketchUp Help forum.
Luckily for me, help came in the guise of Gaieus and Panzerlite -
Help thread: 'How to create a rounded wingtip' - who advised me on the best way to produce the semi-teardrop shape I wanted. And in this post I will take you through how I created the lower wings of my aeroplane model.
1. The wing profileA wing profile is a highly sophisticated piece of technology. But, for the simplified model I wanted to make I would not be creating a completely authentic profile. I used the 'pull' tool to turn the profile into a panel.
The top profile section (red) is an authentic profile – traced from an original blueprint for the Nieuport 17 fighter. The bottom panel (green) shows my simplification of the profile, removing many of the curves, flattening the bottom and making the profile on a horizontal plane. This will become important when I ‘lathe’ the profile later to make the wingtip.
2. Making the wing panelsI am making the lower wing out of ten identical panels (move/copy/x10), this is just to give the impression of the wing 'ribs' of the original.
3. Lathing the profile into the wingtipNext I copied the profile section and prepared a circle in order to 'lathe' ('Follow Me' tool) the profile into a teardrop shape.
4. Quartering the teardropI now want to quarter the teardrop shape into four segments. I do this by drawing a flat plane through the center of the object, making the plane (rectangle) a grouped object. I always
group objects which I am using to INTERSECT with other objects. I have found this makes intersections neater and more successful.
Having intersected through the vertical plane, and finish by intersecting through the horizontal. discarding the three unwanted segments, I end up with the following quarter teardrop shape:
5. Fitting the teardrop wing-tip to the wing panelsNothing difficult here, I simply join the wing tip to it's adjacent panel - remembering to create a face on the bottom of the wing-tip of course.
6. Orientating the wingThe lower wing of the Nieuport 17 isn't straight, it's actually slightly swept back and angled upward towards the tip. I used the rotate tool to rotate the wing to the correct final orientation.
7. The finished wing!Well, that wasn't too difficult. Although I have to stress that a bit of planning and a bit of judicious simplification of the original wing profile helped make this easy. Had I attempted to make the wing using the authentic profile things would have been a lot more difficult.
However, for my goal of a uncomplex representation of the plane the simplified component are just right. This simplified model would be ideal for using as a component itself inside another model as it simplicity gives it a relatively small file size.
An authentic rendering of the same plane would result in a huge file size. So even before you start you must plan what you want to use the model for, and this will decide for you just how complex (and authentic) your model is going to be.
