AutoCAD是一种非常实用的计算机辅助设计软件。目前,它已成为业界标准,被广泛应用于机械、建筑、电子、航天、造船、石油化工、土木工程、冶金、气象、纺织、轻工等领域。我们分享的这部cad2009视频教程介绍了AutoCAD 2009基本操作、建筑总平面图的绘制、建筑平面图的绘制、建筑剖面图的绘制、给排水施工图的绘制等内容。欢迎想学习这方面知识的朋友来本站观看、学习!
AutoCAD是美国Autodesk公司首次于1982年开发的自动计算机辅助设计软件,用于二维绘图、详细绘制、设计文档和基本三维设计。现已经成为国际上广为流行的绘图工具。AutoCAD具有良好的用户界面,通过交互菜单或命令行方式便可以进行各种操作。它的多文档设计环境,让非计算机专业人员也能很快地学会使用。在不断实践的过程中更好地掌握它的各种应用和开发技巧,从而不断提高工作效率。AutoCAD具有广泛的适应性,它可以在各种操作系统支持的微型计算机和工作站上运行。
AutoCAD的特点:⑴具有完善的图形绘制功能。⑵有强大的图形编辑功能。⑶可以采用多种方式进行二次开发或用户定制。⑷可以进行多种图形格式的转换,具有较强的数据交换能力。⑸支持多种硬件设备。⑹支持多种操作平台⑺具有通用性、易用性,适用于各类用户此外,从AutoCAD2000开始,该系统又增添了许多强大的功能,如AutoCAD设计中心(ADC)、多文档设计环境(MDE)、Internet驱动、新的对象捕捉功能、增强的标注功能以及局部打开和局部加载的功能。
AutoCAD尽管有强大的图形功能,但表格处理功能相对较弱,而在实际工作中,往往需要在AutoCAD中制作各种表格,如工程数量表等,如何高效制作表格,是一个很实用的问题。
在AutoCAD环境下用手工画线方法绘制表格,然后,再在表格中填写文字,不但效率低下,而且,很难精确控制文字的书写位置,文字排版也很成问题。尽管AutoCAD支持对象链接与嵌入,可以插入Word或Excel表格,但是一方面修改起来不是很方便,一点小小的修改就得进入Word或Excel,修改完成后,又得退回到AutoCAD,另一方面,一些特殊符号如一级钢筋符号以及二级钢筋符号等,在Word或Excel中很难输入,那么有没有两全其美的方法呢,经过探索,可以这样较好解决:先在Excel中制完表格,复制到剪贴板,然后再在AutoCAD环境下选择edit菜单中的Paste special,选择作为AutoCAD Entities,确定以后,表格即转化成AutoCAD实体,用explode打开,即可以编辑其中的线条及方字,非常方便。
