cad lisp肿么把直线改成有规则的波浪线

CAD

要将直线变成有规则的波浪线，可以使用CAD软件中的LISP语言来实现。以下是一个简单的示例程序：(defun make-wavy-line (start x-spread end) (let* ((length (+ end start)) (midpoint (arithmetic mean start end)) (wave-height (random (min (sqrt (+ (* 10 x-spread) (* 10000000000000))) 100))) (wave-frequency 8)) (let ((nodes (make-list length (lambda () (list midpoint (+ midpoint (wave-height (* wave-frequency (***))) (* wave-frequency (* -1000))))) :start start :end end))) (dolist (node nodes) (setq loc (* node midpoint)) (setq pt (list 0 0)) (setq pt1 (list 0 loc)) (setq pt2 (list loc loc)) (setq pt3 (list loc loc)) (setq pt4 (list loc loc)) (setq pt5 (list 0 loc)) (setq pt6 (list loc loc)) (setq pt7 (list loc loc)) (setq pt8 (list loc loc)) (setq pt9 (list loc loc)) (setq pt10 (list 0 loc)) (setq pt11 (list loc loc)) (setq pt12 (list loc loc)) (setq pt13 (list loc loc)) (setq pt14 (list loc loc)) (setq pt15 (list loc loc)) (setq pt16 (list loc loc)) (setq pt17 (list loc loc)) (setq pt18 (list loc loc)) (setq pt19 (list loc loc)) (setq pt20 (list loc loc) (setq pline (list pt1 pt2 pt3 pt4 pt5 pt6 pt7 pt8 pt9 pt10 pt11 pt12 pt13 pt14 pt15 pt16 pt17 pt18 pt19 pt20)) (insert-pline pline))) (return t))这个程序定义了一个名为"make-wavy-line"的函数，它接受三个参数：起点、直线的宽度和终点。在函数内部，首先计算出波浪线的长度、波高和波频率，并生成一个由中间点连接的波浪线。然后，将这些点转换成CAD中可以显示的点，并用插入点命令插入这些点。最后返回一个由这些插入点组成的曲线对象。这个程序只是一个简单的示例，你可以根据需要进行修改和调整。请确保在使用LISP语言之前熟悉CAD软件中LISP语言的基本概念和语法。希望对您有所帮助！
