【摘要】 提出了利用现代新技术解决工程制图中的重点、难点问题。在三维造型过程中阐述复杂零件的读图和尺寸标注方法,并通过实例进行说明。在整个三维造型的过程中充分利用软件系统提供的功能,不仅能使平面的视图和空间的立体瞬间联系起来,使零件的读图和尺寸标注过程变得更加生动有趣,而且在三维造型的过程中理解零件图中相贯线的形成以及尺寸标注也变得更加简单。更多还原

【Abstract】 This paper puts forward a new method to solve the key problems in engineering drawing.Reading and dimensioning of the complicated assembly-drawings are explained in course of 3D solid modeling by giving examples.Full utilization of the functions of software can not only instantaneously connect the plane view with the three-dimensional part and make the reading and dimensioning of assembly-drawings more interesting,but also make it easier to understand the intersecting lines and dimensions in the assembly-drawings in course of 3D solid modeling.更多还原
