If I place it after the change command, it gives me a error message.&nbsp; I really do not understand the purpose of this command at all.&nbsp; If I have to place it immediately after MEMB INCIDENCE definition, why bother modeling the members?</p> <p></p> <p>Any thought on how I can develop this model to simulate the progression of the demolition?</p> <p></p><div style="clear:both;"></div>
