In dimensioning a drawing, the Numbers placed in the dimension lines represent dimension that are only approximate and do not represent any degree ofaccuracy unless so stated by the designer.
It guides the formation of the three-dimensional numerical bender's data and supplies a algorithm of checking the accuracyof the drawing through observation the three-dimensional virtual image.
提供了一种通过生成立体的三维虚拟图像来检查设计图纸准确性的计算方法。
