【摘要】 工科专业学生,特别是机械和模具专业的学生,无论课程设计、毕业设计都要手绘工程图,以往都是通过丁字尺在图板上绘制,使用不方便,效率低,操作的不熟悉带来的是作图效果的不理想,使学生产生畏难心理,最终导致课程设计完成效果不理想。基于此,设计一款多功能工程绘图尺,能大大加快工程图特别是模具图的绘制速度,提高课程设计的教学质量和教学效果,增强学生手绘工程图的技能,从而为今后的社会实践和就业打下坚实的基础。更多还原

【Abstract】 Engineering students,especially machinery and mold professional students,regardless of the curriculum design,graduation design to hand draw engineering drawings,the past is by drawing the T-square is on board,the useis not convenient,the efficiency is low,are not familiar with the operation is brought about by the drawing effect is not ideal,so that students have a psychological fear,eventually leading to the curriculum complete the design of the effect is not ideal. Based on this,to design a multifunctional engineering drawing ruler,can greatly speed up the engineering drawings especially mould drawing speed,improve the quality of teaching and the teaching effect of the course of design,to enhance students’ hand-painted engineering drawing skills,and a solid foundation for the future of social practice and get a job.更多还原
