      5.1. Use the cursor "pick box" to SELECT any point on the seam line of the pattern piece you are slashing.  The computer will then say:
        Select objects:
            Select Object to be cut (pline):
            Select Cutting line (pline):

5.2. Use the cursor "pick box" to SELECT the cutting line you have drawn.
    You will see the a rapid series of command statements running in the command prompt area.  If there are some complex curves this will take longer than if you are CUTting a piece made up mostly of straight lines.  AutoCAD curve lines are made up of tiny dash lines and the computer has to identify each one as part of the CUT process.
    As soon as the calculations are finished you will see one side of the pattern piece turn blue and the other half turn green.  When this has happened the two pieces are now two separate "CLOSEd" polygons.  If you next divide one of those pieces, the two new pieces will again be one blue and one green.

NOTE:  AutoCAD® has a "CHANGE" command that will allow you to change line colors from the color in which they were drawn to the color of your choice (red, yellow, blue, green, white, magenta, cyan).  When you see black lines on the screen, the computer thinks they are white.  You can draw with colored lines by using the command COLOR and then tell the computer one of the seven basic color names.  It is time effective to wait until you are finished with the pattern and then use CHANGE to make every thing have the same color lines.  This is only useful to you as a visual organizing device.  
    A multi-pen plotter will PLOT all the lines in the appropriate color or all the same color on depending on what you tell the plotter to do.  If you are using a regular black and white PRINTER all lines will be the same color.  Single pen plotters also draws all the lines the same color.  The CHANGE command will be detailed later.
