I sorry for my question ? I try to draw the machine depend on what the user give as input. Ex: if the user enter a*b the system must show a specific machine. so i try to figure all the image needed by the system to draw different kind of machine but my problem how to tell the system to insert this figure followed by that one regarding the user input, off course there is a rule to chose which is defined. "In other language I try to figure out the machine(DFA) that accept this kind of language that is represented by the user input" Thanks a lot
