CAD二次开发Visual_LISP指南
CAD二次开发Visual_LISP指南CAD二次开发是指在CAD软件平台上进行个性化开发和定制化编程，以满足用户特定需求Visual LISP是AutoCAD软件的一种编程语言，通过使用Visual LISP语言可以对AutoCAD进行二次开发。
下面是CAD二次开发Visual LISP的指南，希望对开发人员有所帮助。
一、入门准备1.学习基础知识在开始进行CAD二次开发前，需要充分了解AutoCAD软件的基本功能和特点，熟悉CAD软件的界面、命令、对象模型以及常用API（应用程序接口）等。
2.掌握Visual LISP语言Visual LISP是CAD软件平台上的一种编程语言，与AutoLISP类似。
学习和掌握Visual LISP语言是进行CAD二次开发的基础。
可以通过学习书籍、在线教程和参考文档等途径来提高自己的编程能力。
3.安装开发工具需要安装CAD软件的开发工具，例如AutoCAD自带的AutoCAD Developer Tools或者Visual LISP IDE等。
这些工具提供了编写、调试和管理二次开发项目的必要环境。
二、开始二次开发1.确定需求在进行CAD二次开发前，需要明确开发的具体需求和目的。
这可以包括添加自定义命令、修改现有功能、创建用户界面等等。
确保清晰地定义需求和目标，以便更好地进行开发工作。
2.编写代码通过Visual LISP语言编写代码来实现二次开发的需求。
VisualLISP提供了一系列的函数和命令，可以对AutoCAD的对象模型进行访问和操作。
根据需求，编写相应的函数、宏和命令，实现具体的功能。
3.调试和测试在编写代码后，进行调试和测试是不可或缺的步骤。
通过运行调试器、打印日志、进行单元测试等方式来验证代码的正确性和稳定性。
及时修复和调整代码中的问题，确保其能够正常运行。
4.文档和发布完成开发工作后，建议对代码进行适当的文档整理和注释，方便后续的维护和管理。

在CAD中加载lisp等应用程序的方法有下列几种方式：一、手动加载 1、依次点击菜单项的工具加载应用程序，打开加载/卸载应用程序对话框；或直接输入appload命令打开；见下图： 2、在打开的对话框中选择相应的lisp等应用程序后点击加载即可。
二、自动加载 1、
在CAD中加载lisp等应用程序的方法有下列几种方式：
一、手动加载
1、依次点击菜单项的“工具”→“加载应用程序”，打开加载/卸载应用程序对话框；或直接输入“appload”命令打
开；见下图：
2、在打开的对话框中选择相应的lisp等应用程序后点击“加载”即可。
二、自动加载
1、在上述手动加载的第1步打开的对话框中点击“内容”按钮；
2、在打开的启动组对话框中点击“添加”，从而将相应lisp等应用程序加入启动列表；
3、在每次打开CAD窗口时即可自动加载启动列表中的程序。
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 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)))
