autolisp教程 高分悬赏，请高手用AutoLISP编写4个小程序：

函数名为"tuxing"，要求执行此函数时使用键盘输入两个同心圆的圆心坐标和每个圆的半径值，然后：
1.自动绘出这两个圆和水平，垂直的两条中心线
2.自动绘出这连个圆和与圆同心的正方形
请根据以上两个条件编写两个程序

函数名为"tuxing"，要求执行此函数时使用键盘输入一个圆的圆心坐标和半径值，然后：
1.自动绘出该圆，和与该圆在左右侧相切且直径相同的另外两个圆
2.自动绘出该圆和与该圆同心的正方形
请根据以上两个条件编写两个程序

跪求高手解答，高分悬赏，之后再追家100分！
可以将程序拆分成4个吗？因为有4个题目，万分感谢！

Answer 1

（一）
(defun c:tuxing1 ()
(setq Rd (getdist "\n R=:"))
(setq Rx (getdist "\n r=:"))
(setq p0 (getPoint "\n Enter Center of Circle"))
(setq p1 (list(car p0) (+ (+ (cadr p0) Rd) 5)))
(setq p2 (list(- (- (car p0) Rd) 5) (cadr p0)))
(setq p3 (list(car p0) (- (- (cadr p0) Rd) 5)))
(setq p4 (list(+ (+ (car p0) Rd) 5) (cadr p0)))
(Command "line" p1 p3"")
(Command "line" p2 p4"")
(Command "circle" p0 Rd)
(Command "circle" p0 RX)
)
（二）
(defun c:tuxing2 ()
(setq Rd (getdist "\n R=:"))
(setq Rx (getdist "\n r=:"))
(setq p0 (getPoint "\n Enter Center of Circle"))
(setq a1 (list(+ (car p0) (* (cos (/ pi 4)) Rx)) (+ (cadr p0) (* (cos (/ pi 4)) Rx))))
(setq a2 (list(- (car p0) (* (cos (/ pi 4)) Rx)) (cadr a1)))
(setq a3 (list(car a2) (- (cadr p0) (* (cos (/ pi 4)) Rx))))
(setq a4 (list(car a1) (cadr a3)))
(setq b1 (list(+ (car p0) (* (cos (/ pi 4)) Rd)) (+ (cadr p0) (* (cos (/ pi 4)) Rd))))
(setq b2 (list(- (car p0) (* (cos (/ pi 4)) Rd)) (cadr b1)))
(setq b3 (list(car b2) (- (cadr p0) (* (cos (/ pi 4)) Rd))))
(setq b4 (list(car b1) (cadr b3)))
(Command "line" a1 a2 a3 a4 a1"")
(Command "line" b1 b2 b3 b4 b1"")
(Command "circle" p0 Rd)
(Command "circle" p0 RX)
)
（三）
(defun c:tuxing3 ()
(setq r (getdist "\n r=:"))
(setq p0 (getPoint "\n Enter Center of Circle"))
(setq p1 (list(- (car p0) (* r 2)) (cadr p0)))
setq p2 (list(+ (car p0) (* r 2)) (cadr p0)))
((Command "circle" p0 r)
(Command "circle" p1 r)
(Command "circle" p2 r)
)
（四）
(defun c:tuxing4 ()
(setq r (getdist "\n r=:"))
(setq p0 (getPoint "\n Enter Center of Circle"))
(setq a1 (list(+ (car p0) (* (cos (/ pi 4)) r)) (+ (cadr p0) (* (cos (/ pi 4)) r))))
(setq a2 (list(- (car p0) (* (cos (/ pi 4)) r)) (cadr a1)))
(setq a3 (list(car a2) (- (cadr p0) (* (cos (/ pi 4)) r))))
(setq a4 (list(car a1) (cadr a3)))
(Command "line" a1 a2 a3 a4 a1"")
(Command "circle" p0 r)
）
可以了，你试试吧！
