Answer» Correct choice is (a) We can generate flat WRAP surface by using linear interpolation method To explain: A flat wrap surface has same tangent ANGLES for DIFFERENT conic curves. When linear interpolation method is used, it does not always provide constant cross-sections or c/s with same tangent angles. Hence, it MAY or may not produce flat wrap. We can generate flat wrap by providing some CONSTRAINTS as well.
