cad分解多重引用块分解.doc

1把以下内容用记事本保存为 lsp 文件(如 ) 2用 cad 打开图 3输入命令“ appload ”,加载 exm 4输入命令“ exm ”既可把“多重插入块”转换为“普通块” 5然后既可用“ explode ”分解。;;转换“多重插入块”为“普通块”。(DEFUN C:exm () (setvar "cmdecho" 0) (SETQ STM (car (ENTSEL "\n 点取多重块"))) (while stm (setq e (entget stm)) (setq stlx (cdr (assoc 0 e))) (if (= stlx "INSERT") (PROGN (setq r_zm70 (assoc 70 e)) (setq c_zm71 (assoc 71 e)) (setq r_dist_zm44 (assoc 44 e)) (setq c_dist_zm45 (assoc 45 e)) (setq e (subst (cons 44 0) r_dist_zm44 e)) (setq e (subst (cons 45 0) c_dist_zm45 e)) (setq e (subst (cons 70 0) r_zm70 e)) (setq e (subst (cons 71 0) c_zm71 e)) (setq e (subst (list 100"AcDbBlockReference") (list 100"AcDbMInsertBlock") e)) (entmake e) (entdel stm) )) (SETQ STM (car (ENTSEL "\n 点取下一多重块"))) ) (setvar "cmdecho" 1) )
