【Abstract】 In this paper, the parametric design technology for curves is studied and analyzed. And six key points of curves parametric design are proposed that include the classification of curves, the extraction of curves dimension, the induction of basic constraint relations, the geometrical and topological structure representation of curves and surfaces, the geometric reasoning method for constraints, and the satisfaction way for constraints. The dimensions of curves are discussed. And also the satisfaction method of constraint relations among curves is researched. Finally, an example is analyzed.更多还原
