2.0 PROGRAM DESCRIPTION AND INSTRUCTIONS

   2.1 DESCRIPTION
       
       SECTION is a cross sectional properties calculation
       program.  The results obtained from SECTION can be 
       used in a structural analysis.

       SECTION allows the user to create custom
       cross sections graphically using rectangular 
       elements.  Area, location of centroid, and moments 
       of inertia (including principal moments of inertia)
       are automatically calculated.  Original, centroidal, 
       and principal axes can be toggled on and off.  A 
       grid is also available to aid in construction of the
       cross section.

   2.2 INSTRUCTIONS

       To create a cross section and get its properties:

       Step 1 : Define the Rectangular Element's Properties

          Choose Element and then Rectangle from the menu or
          click on the Create Rectangle button.  Enter the
          height and width of the rectangular element and
          choose a corner that will be used in locating
          the element.  Click the OK button.

       Step 2 : Locate the Rectangular Element

	  Click on one of the points highlighted by a red
          circle to locate the corner of the rectangular
          element that was chosen in Step 1.

       Step 3 : Orient the Rectangular Element

          Rotate the rectangular element by moving the 
          mouse around the point highlighted with a black
          circle.  When the element is at the proper
          orientation, click the mouse to freeze the 
          element's position.

       Step 4 : Repeat Steps 1 Through 3 Until All Elements
                Are Created

       Step 5 : Adjust the Grid and Axes

          Click the Show the Grid button to toggle the grid
          visibility.  Choose Grid and then Grid Spacing
          from the menu to change the grid spacing.  Use
          the Axes menu item or the Axes buttons on the 
          toolbar to toggle the visibility of the different
          axes.

	  Original Axes:   The coordinate system the elements
                           are defined in.

          Centroidal Axes: Parallel to the Original Axes, but
                           originate at the centroid of the
                           section.

	  Principal Axes:  Originate at the centroid of the
                           section.  The axes about which the
                           section's maximum and minimum 
		           (Principal) moments of inertia 
			   fall. 
       
       Step 6 : View and Print the Results

          Observe the calculated section properties on the
          status bar at the bottom of the window.  Choose
          File and then Print from the menu or click the
          Print button to print the section and its 
          properties.  Print Preview is also available on
          the menu and on the toolbar.  

       Step 7 : Save the Cross Section

          Choose File and then Save or click the Save button
          to save the cross section and the grid and axes
          options you have chosen.
