A method for providing subscription and notification in an engineering design system includes using a client terminal to define one or more segments of interest of an engineering design maintained on a server (S21). The server is periodically polled, from the client terminal, to request status information pertaining to each of the segments of interest (S22). The status information is received from the server (S23). The received status information is compared with prior status information obtained during a previous receipt of status information to determine whether one or more of the segments of interest have been modified since the previous receipt of status information (S24). A user of the client terminal is alerted when it is determined that one or more of the segments of interest has been modified (S25). |
