[分享]-array中，用ucs进行有角度阵列

可是有点小缺憾，几何计算器cal，中的ptl命令怎么用？
求1/4点的时候我用了2句，有点麻烦(Defun C:loadq ( / pt1 pt2 pt0 pt3 pt4 pt5 pt6 qh qle qan n ent )
   (setvar "cmdecho" 1)
   (command "layer" "m" "loadq" "C" 2 "loadq" "")
   (command "linetype" "S" "BYLAYER" "")
   (setq pt1 (getpoint "均布荷载起点a:"))
   (setq pt2 (getpoint pt1 "\n均布荷载终点:"))
   (setq pt0 (getpoint pt2 "\n均布荷载高度h:"))
   (setq qh (distance pt2 pt0))
   (setq qan (angle pt1 pt2))
   (setq pt3 (polar pt2 (+ qan (/ pi 2)) qh))
   (setq pt4 (polar pt1 (+ qan (/ pi 2)) qh))
   (command "_.pline" pt1 "w" 0 0 pt4 pt3 pt2 "c")
   (setq qlen (distance pt1 pt2))
   (setq n (fix (/ qlen qh)))
   (if (< n 6)
   (setq n 6)
   )
   (if (null cal)(arxload"geomcal"))
   (setq pt5 (c:cal "(pt1 + pt4) / 2"))
   (setq pt6 (c:cal "(pt1 + pt5) / 2"))
   (command "_.pline" pt1 "w" 0 (/ qh 8) pt6 "w" 0 0 pt4 "")
   (setq ent (entlast))
   (command "_.ucs" "n" "3" pt1 pt2 pt3)
   (command "array" ent "" "" "" (+ n 1) (/ qlen n)
   (command "_.ucs" "w" )
   )
)
