Does anybody know how to design model aircraft from 3-view drawings?

Let say...I want to design Christen Eagle what should I do next
Calculate wing area? weight? Power? Or....I just plotted down from the 3-view drawing? And how to determine the airfoil should I choose?

Thank you very much for anybody telling me...: )

I have designed several models from 3-view drawings. First, I must deceide the size of model I want. In order to do this, I must deceide how the model is to fly. If I want a model that flies and lands slowly, it must have a low wing loading (wing area divided by weight- in USA, usually square feet divided by weight in ounces.) If the model is to be fast, it will have a higher wing loading. Larger models can have higher wing loading than small ones for similar flight characteristics. What size engine or motor will I use? For a .20 to .25 two stroke, or .30 to .40 four stroke, I want to keep the weight down to around 3 pounds. For a .40 to .46 two stroke, or .60 four stroke, I want a weight of 4 to 5 pounds. A .60 two stroke or .91 four stroke would carry 6 to 8 pounds, etc.
For example, if I want a model for a .40 two stroke engine that will fly and land at a moderate speed, then I plan for about 5 pounds. A moderate wing loading for this weight is 20 ounces per sq. ft. 5 pounds is 80 ounces, and dividing this by 20 gives 4 sqare feet of wing area, or 576 square inches. Find the aspect ratio of the wing in the 3-view ( this is the wingspan divided by the chord, or average width). If the ratio is, for instance, 6, then the model wingspan will be 6 times the average chord, or width. By trial and error, I find that a width of 9.9 times the aspect ratio 6 gives a wingspan of 58.8 inches, and an area of 576.
Now I know how big to make the model- I scale up the 3-view so that the wingspan is 58.8 inches.
The best way to design the structure is to use a plan of a similar size model to determine the size of materials, spacing of ribs (unless you want the same number of ribs as the 3-view). I hope this is of some help. Designing a model is not simple, but it allows one to build a unique model. ..like this 1929 Church-Heath racer I designed from a 3-view..John

Thank you very much, that's very useful for me...

Designing a scale biplane like the Christen "Eagle" would be a difficult task. I would see if there is a kit for a Pitts Special around the size you want, and convert it into an "Eagle" which would be easy since it was copied from a Pitts Special.
