Project Details
I use some CAD/3D software called "Carrara Studio". You can get more information about it at Eovia.
Paul and discussed how we would allow access to the internal structure of the model, and also how to install a scale interior. We decided to allow for the nose of the aircraft to be separable, as in these images. Paul sent me the top image, which he created by manipulating an image of the CAD model I sent him. I followed up by actually re-creating Paul's concept with our CAD model. (bottom image)
As we began to gather more documentation, it became apparent that all the drawings did not match. The image here is a composite of five different versions of the side view, superimposed on top of each other, showing the differences. We both took photos of the B200s in our area, and eventually decided on a particular drawing from Raytheon to use as the basis for our model. This decision was based on our belief that it was the most accurate, and also with the idea in mind that the Raytheon documentation was the most likely set of data that we would eventually present to scale judges at contests.
I created 3 virtual pieces of "paper", on which I could place the drawings. Using this approach, I could quickly compare our CAD model to many different drawings, and get a feel for which ones made the most sense to use. Small discrepancies show up quickly when you look at them from a 3D point of view. You can see that this set of Raytheon drawings, from their "Walkaround" brochure, does not exactly match the more precise drawings we selected.
