1. Model date setting
      Set the date for the entire model. A date consists of a start date,
      an scheduled completion date, and a completion date.
     

       Click the date setting buttons for Start Date, Scheduled Completion Date,
      and Completion Date to set the dates.
           

        The date setting is set by clicking the day you want to set
       and clicking the save button.
       The model-wide completion date setting can be set
       if all L classes of the model havecompletion dates set.
       Setting a completion date for a model prevents editing of the model.
       If you want to cancel the model completion date,
       click the date setting button of the completion date and
       the cancel completion button will appear.
      

       Click the Uncomplete button to make the completion date blank and editable.
      To set the date for the L class and S class,
      use the same procedure as for setting the date for the entire model.
