《数学通报》2012年第9期刊登的《“斜二测直观图不是平行投影空间图形”的证明》(以下简称文[1])一文,其论点“斜二测直观图不是平行投影空间图形”及“用斜二测画法画出的直观图并不符合平行投影原理”是错误的.事实上,用斜二测画法画出的直观图是轴测图的一种,而轴测图就是以投影面为画面,按平行投影原理画出的一种图象.其理论依据是波克—许华尔兹定理.因此,用斜二测画法画出的直观图符合 The “” oblique second test visual map published in the 9th issue of the “Mathematical Bulletin” 2012 is not a proof of the parallel projection spatial pattern “ (hereinafter referred to as ”[1]), and its argument “” The projected spatial graphics “and”&&&&.&&&&&&& The oblique visual plots drawn by the oblique second plot method do not conform to the principle of parallel projection". It is wrong. In fact, the visual plots drawn with diagonal plots are axonometric. One is that an axonometric drawing is an image based on the principle of parallel projection with the projection plane as a picture. Its theoretical basis is the Polk-Xuertz’s theorem. Therefore, an intuitive drawing drawn with oblique second plotting is used. meets the
