把对象插入到指定坐标的位置

entmake生成普通块
(defun emkblk (ss pt name / i)
  (entmake (list '(0 . "block") (cons 2 name) '(70 . 0) (cons 10 pt)))
  (repeat (setq i (sslength ss))    (entmake (cdr (entget (ssname ss (setq i (1- i))))))  )
  (entmake '((0 . "ENDBLK")))
  (command "_.erase" ss "")
  (entmake (list '(0 . "INSERT") (cons 2 name) (cons 10 pt)))
)
  
entmake插入普通块
  (entmake (list '(0 . "INSERT") (cons 2 name) (cons 10 pt)))
entmake生成无名块
(defun emkunameblk (ss pt / i name)
  (entmake (list '(0 . "block") '(2 . "*U") '(70 . 1) (cons 10 pt)))
  (repeat (setq i (sslength ss))    (entmake (cdr (entget (ssname ss (setq i (1- i))))))  )
  (setq name (entmake '((0 . "ENDBLK"))))
  (command "_.erase" ss "")
  (entmake (list '(0 . "INSERT") (cons 2 name) (cons 10 pt)))
