如何将文字高度设置成默认上一次选择的高度
感谢<统计周长面积（并在图示中显示出来）>的原作者；感谢本论坛yshf、lishucheng96对代码的补充。

(defun c:qq1 (/ d ent f i lst m2 obj pt ss txt x y)
(setq TextHeight (getdist "\n输入标注文字高度:")
Textbh (getstring "\n输入编号前缀:"))
(defun maketext (txt pt) ; 生成文字子函数
(entmake (list '(0 . "TEXT") (cons 62 1) (cons 10 pt) (cons 40 TextHeight) (cons 1 txt) '(41 . 0.8)))
)
(setvar "cmdecho" 0)
(vl-load-com)
(setq ss (ssget) ent (entlast))
(command ".region" ss "")
(setq ss (ssadd)lst nil)
(while (setq ent (entnext ent))
(if (= (cdr (assoc 0 (entget ent))) "REGION")
(setq obj (vlax-ename->vla-object ent)
pt (vlax-safearray->list (vlax-variant-value (vla-get-centroid obj)))
m2 (rtos (* 0.000001 (vla-get-area obj)) 2 3)
d (rtos (* 0.001 (vla-get-perimeter obj)) 2 3)
lst (cons (list pt m2 d) lst)
)
)
)
(command ".undo" "")
(setq lst (vl-sort lst (function (lambda (x y)(< (car (car x)) (car (car y)))))))
(setq lst (vl-sort lst (function (lambda (x y)(> (cadr (car x)) (cadr (car y)))))))
(write-line "编号\t周长(m)\t面积(m2)" )
(setq i 1)
(foreach x lst
(setq pt (car x) m2 (cadr x) d (caddr x))
(maketext (strcat Textbh (itoa i)) (list (car pt) (+ (cadr pt) (* 1.2 TextHeight))))
(maketext (strcat "L=" d "m") pt)
(maketext (strcat "S=" m2 "m\u+00b2") (list (car pt) (- (cadr pt) (* 1.2 TextHeight))))
(write-line (strcat (strcat Textbh (itoa i)) "\t" d "\t" m2) f)
(setq i (1+ i))
)
(princ)
)
本次想向各位询问三个问题：
1、如何将上一次输入的字体高度默认为下一次的参数（在不选择的条件下）？
2、如果我想自动默认字体高度，应该改变哪一段代码？
3、如何我想将文字高度设为以屏幕固定比例（像点样式中的根据屏幕比例），应该如何增加代码？
