If you are designing a four-sided tube using a simple drawing program, do you a. Create a large rectangle and add three equidistant 'bisecting' lines within it? ex. a 1 inch wide square tube would consist of a 4 inch wide rectangle an lines at the 1, 2, and 3 inch marks or b. Create a single rectangle and daisychain three more to it? ex. create a 1 inch wide rectangle and add another 1 inch wide rectangle adjacent to it and so on. (Of course the two adjacent lines would actually occupy the same space so as not to introduce an additional line thickness) The same question applies to creating rudders, wings, etc. Opinions?
