Scripts are strings of code that specify a task or series of tasks to be performed immediately after the script is run. Scripts are great, but they offer less interaction - possibillities for the user. That is, they are implemented as a commad would be directly in the application environment, executed on keypress and interpreted as actions. In Architectural design scripts have been used for the purpose of running a routine that shapes the model in a predictable way. It is and has been a great time - saver.scripts can also be interactive, but basically they are direcly executed, so you would have to call a plugin or extension in the script in order to get any external functions, that is functionality not already available in some way through the basic software itself.
