摘要
针对高职院校机械类专业开设的制图测绘实训课程,分析了目前制图测绘教学中出现的学生忽视测量准确性、零部件表达不准确、疲于完成图纸绘制等问题,提出了将三维建模引入制图测绘教学,利用三维模型与二维图纸的转换提升零部件表达的准确性,利用三维装配来约束零件尺寸测量的准确性,同时由三维模型直接生成二维工程图,大大提高了绘图的速度和准确度,也符合现代设计理念。
According to the practical courses of drawing mapping for the students majored in mechanics in higher vocational colleges and universities,this paper analyzes the problems neglected by the students in drawing mapping teaching such as the measurement precision,inaccurate expression for spare parts,tiredness of finishing drawing and so on,proposes to introduce 3D modeling into drawing mapping teaching,to raise the precision for the expression of spare parts by taking the advantage of the conversion between 3D model and 2D drawing,to use 3D assembly to constrain the precision of spare parts size measurement,and to generate 2D engineering drawing directly from 3D model,which greatly boosts the speed and accuracy of the drawing and which befits modern design idea.
