四、设计素描的画法 设计素描因其目的及对象物的特点,它并不要求象数学公式与几何学那样严格准确,它是介于理性与感性间一种思维,是方法与感觉并用,经验与程式并存的一门课,在比例大小上凭感觉与经验确定,彼此间的相互关系与形态过渡靠逻辑推理与几何方法确立。为了培养三维的思维能力和准确的绘制能力,要求每一位绘制者徒手绘制,比例及形态间关系用眼观察确定。 Fourth, the sketch of the design of the design of the sketch because of its purpose and the characteristics of the object, it does not require as strict and accurate as mathematical formulas and geometry, it is a kind of thinking between the rational and emotional, is the method and the feeling of use, A lesson in which experience and program coexist is determined by feelings and experience in terms of proportion. The mutual relations and pattern transitions are established by logical reasoning and geometric methods. In order to cultivate three-dimensional thinking ability and accurate drawing ability, each drawing person is required to draw by hand, and the relationship between the proportion and the form is observed with the eye.
