为了提高绘图效率，以适应现代设计制造的需要。介绍了AutoCAD图块的功能以及属性定义、编辑、属性提取的操作方法，并以两个实例说明了属性块在计算机辅助设计中的应用。运用"属性块"，在产品设计中既可以减少大量的重复工作，又可以提高绘图的效率和质量。 Abstract: In order to improve drawing efficiency to meet the needs of modern design and manufacturing . This paper discussed the function of AutoCAD block， the definition of attribute， the editing of attribute and extraction method of attribute. There were two examples about how to use attribute of block in computer drawing. Using “attribute of block” can reduce a lot of duplication work during product design， and also can improve the efficiency and quality of drawing.
