您只要反向操作，這個程式也可以選中特定型態....

範例1
(defun c:Tt (/ ss)
  (setq ss (ssget))
  (setq ss (SSEntTyp ss "DIMENSION"))
  (command "erase" ss "")
)

範例1.不管選中什麼 TT 只幫你刪掉標註

範例2
(defun c:Tt2 (/ ss Dss Lss)
  (setq ss (ssget))
  (setq Dss (SSEntTyp ss "DIMENSION"))
  (setq Lss (SSEntTyp ss "LEADER"))
  (command "erase" Dss "")
  (command "erase" Lss "")
)

範例2.不管選中什麼 TT 只幫你刪掉標註及引線

(defun SSEntTyp (SSrex entype /  n endata enNamen ssExcluded result)
   (if (/= SSrex nil)
     (progn
       (setq ssExcluded (ssadd))
       (setq n 0)
       (repeat (sslength SSrex)
     (setq enNamen (ssname SSrex n))
     (setq endata (entget enNamen))
     (if (= (cdr (assoc 0 endata)) entype)
       (progn
        (print entype)
        (print (cdr (assoc 0 endata)))
            (setq ssExcluded (ssadd enNamen ssExcluded))
       );;progn
     );;if
     (setq n (+ n 1))
       ) ;;repeat
     );;progn
   );;if
          (setq result ssExcluded)
   )
