;；一、绘制地形图符号1.点状符号对于点状符号，其位置固定，数量较多，且一般都带有一定的标注,可逐个制作属性块图元，单独插入.2。
线状符号利用AutoCAD中强大的线型定义.3.面状符号由充填符号在面域内按一定的排列方式组合而成。
目前Auto CAD在建筑设计、工程施工放样得到广泛应用，Auto CAD在工程测量上的应用，大大减少手算坐标的工程量或帮助人们复核手算坐标的准确性。

CAD中自动画管线图的LISP程序
(defun c:brel(/myosmode horv p p1 p2 p3)
(setq myosmode (getvar "OSMODE"))
(setvar "OSMODE" 0)
(setq p (getpoint "\nSelect point to break:"))
(initget 1P程序
画一些管路原理图时，当代表不同管路的直线在图中相交时，需将在交点处的某一直线断开，再用一半圆连接两断点，使用下面这个LISP编写的程序，只用键入"brel"的命令，其它的就由电脑去完成了。
程序中使用"break"命令截断需要被断开的管线，再用"arc"命令画一半圆连接两断点。变量p读取管线交点；p1、p2为点p的左右或上下两点；p3为连接p1、p2半圆的中点。由于使用"break"命令时若AUTOCAD环境处于对象捕捉方式（OSMODE≠0），则"break"命令截断的p1、p2两点可能为变为p1、p2附近的捕捉点。所以程序开始时用变量myosmode记录系统变量OSMODE，而后设置OSMODE为0，程序结束后再设置还原OSMODE。变量horn判断用户需要断开的是水平线还是垂直线。
(setq p3 (list (car p) (+ (cadr p) 1.5)))
)
(progn
(setq p1 (list (car p) (- (cadr p) 1.5)))
(setq p2 (list (car p) (+ (cadr p) 1.5)))
(setq p3 (list (+ (car p) 1.5) (cadr p)))

CAD中LISP程序使用方法
CAD中LISP程序使用方法2007-08-06 19:13:32| 分类：学习园地 |字号订阅1. 对于提供附件下载的，把附件下载就可以了2. 对于提供的源LISP代码，把代码拷贝、粘贴到一个文件，自己起个名或者若程序里面注释推荐了文件名，就用推荐的，然后保存成扩展名是LSP的文件即可了。
LISP程序使用方法：加载LISP1. 可以使用APPLOAD命令，然后去找到要加载的LISP文件，加载即可。
2. 可以自己从文件管理器把LISP文件拖动到ACAD的图形窗口，也可以加载3. 在命令行后用，(load "c:\\temp\\xxx.lsp")也可以加载，路径名请输入实际的路径。
另：对于一个LSP程序，(defun 后面的既是命令或者函数，一般程序应该有提示，若没有，标志符c:后面的单词是可以在ACAD下使用的命令，既可以在COMMAND:后面直接输入，即可执行。
CAD快速切换图层LISP代码（方法2）给楼主发一个图层更改的lisp程序，按对应数字键就可以切换到相应的图层。
很方便。
0————01————OBJ2————6t3————SCETR。
8————BORDER如果这些不是你想要的图层，将lisp用笔记本打开，把里边的OBJ，6t等图层名改为你想要的就可以了。
以后要切换图层时，按相应的数字键即可。
