Unigraphics(简称UG)广泛应用于航天、汽车、通用机械和电子等领域,是教学和学习首选的三维造型技术软件。将UG软件融入到教学中,能够有效地突破机械制图中的重难点,对机械制图课的授课效果具有很大的影响。本文将具体分析UG软件的优点,将UG软件运用至机械制图的教学实践中,使学生更容易理解机械制图中的重难点,从而学好这门课程。 Unigraphics (referred to as UG) is widely used in aerospace, automotive, general machinery and electronics and other fields, is the preferred three-dimensional modeling technology software for teaching and learning. The UG software into teaching, can effectively break through the heavy mechanical difficulties in the drawing, mechanical drawing lesson teaching has a great impact. This article will analyze the advantages of UG software in detail, and apply UG software to the teaching practice of mechanical drawing so as to make it easier for students to understand the heavy and difficult points in mechanical drawing.
