A draftsman is not the same as an architect. An architect is involved in the design of buildings, while a draftsman produces drawings of architectural designs. A structural engineer is responsible for the structural integrity of a building.

Not exactly. A draftsman is someone who creates detailed drawings of architectural or engineering designs. An architect is someone who designs buildings, and a structural engineer is someone who designs the structure of buildings (ie, the beams, columns, and other supporting elements).
