Dialog boxes and message boxes are the common communication tools for   Mechanica. You use dialog boxes to define such items as modeling entities,   analyses, design studies, and results. You use message boxes to answer questions   that Mechanica may ask as you work. Message boxes also inform you of problems   with your model or provide you with information pertinent to an activity you are   performing. 
             Dialog boxes are windows with entry boxes, lists of options, buttons, and   other items that enable you to apply settings and values to entities, analyses,   and design studies you create or modify. Because dialog boxes are windows, you   can move or close them if necessary. Commands that use dialog boxes open the   dialog boxes automatically when you select the command. Some commands may use   more than one dialog box.  
             Here is an example of a typical Mechanica dialog box. Note that this dialog   box does not contain all of the possible items you might see on a dialog box,   but does include the most common items. 
               
             To apply settings using a dialog box, enter or select values using the items   on the dialog box. When you select a button on a dialog box, additional buttons   or entry boxes related to your selection may appear on the dialog box.  
             The following list describes most dialog box items and how to use them:  
             
             
               
               
               
               
               
                 
                   button  | 
                   Enables you to perform an action.  | 
                  
                 
                   check box   | 
                   Enables you to select an item. From a group of check boxes, you can select   one or many.  | 
                  
                 
                   display-only text   | 
                   Displays a name or value that you cannot edit.   | 
                  
                 
                   entry box  | 
                   Provides a place for you to enter a value, name, or comment.  | 
                  
                 
                   list box  | 
                   Displays a list of items with a scroll bar. You usually select an item on the   list.   | 
                  
                 
                   option menu  | 
                   Enables you to select one of several options. The dialog box displays the   name of the currently selected option.   | 
                  
                 
                   tab  | 
                   Enables you to select an activity to perform on a dialog box. When you click   a tab, the dialog box brings that tab to the forefront for you to fill   out.  | 
                  
                 
                   table  | 
                   Lists a variety of attributes associated with an entity. You use dialog box   tables to select entities that you want Mechanica to act on or that you want to   define. You can insert new rows into dialog box tables and delete existing rows.   In some cases, you can edit the contents of a table by right-clicking on an   item.   | 
                  
               
              
             Mechanica displays message boxes to provide you with important information   you need before continuing with a command. Some Mechanica commands use message   boxes to display a question or a message. If this is the case, the message box   includes buttons that you can use to respond to the question. You select the   buttons on these message boxes with the left mouse button. You can also select   the default response, the button with the double border, by pressing RETURN.   Like dialog boxes, a message box is a separate window that you can move or   close.
