             Entity selected is not a polyline
             Do you want to turn it into one? <Y>
Since Y is in <>s this means that Y(ES) is the "default command".  All you need to do is click ENTER.

    If the computer sees this line as a multi-segment line it will go directly to saying:
          Close/Join/Width/Edit vertex/Fit curve/Spline curve/Decurve/Undo/eXit <X>:
     without the intervening question.  SELECT J(OIN) and  click ENTER.

15.2.  You should see at least a flicker in the seam line as the computer processes connecting the segments into one continuous line.  The lines that are JOINed will probably turn color (usually blue).  If the computer has really JOINed all the lines properly the computer will now say:
          Open/Join/Width/Edit vertex/Fit curve/Spline curve/Decurve/Undo/eXit <X>:

    The key word is O(PEN).  This indicates that the computer now sees the pattern seam lines as a CLOSED polygon.  If the "command prompt" still begins` with C(LOSE), this is an indication that you have not been successful in joining the seam segments into a continuous line.  You can try ENTERing the C(LOSE) command.  Some times this will cause the computer to complete the polyline.  Some times you will see that it will Close in a strange shape with a line cutting across the inside of the pattern piece. If this happens you will need to trouble shoot to find out what the error is in your drawing of the pattern piece.  (This should not happen if you have used the SNAPTO sub-commands to join all of your line segments.) If C(LOSE) still begins the "command string", CLICK ENTER since X(eXit) appears in <>s as the "default command".  (see Section 16 of this chapter for trouble shooting.)


    In a case where you want to turn a sequence of straight lines into a curve (such as a leg 'o mutton sleeve cap), first SELECT PEDIT.

15.3.1.   Point at any 1 of the lines that you want to join.

15.3.2.  Then SELECT  J(OIN) and then SELECT all the "broken" line  lines you want to become the new curved seam line.  Depending on how easy it is to SELECT with a W(INDOW), you may need to repeat this process more than one time to J(OIN).

15.3.3.  Next SELECT FIT CURVE and click ENTER.  You will see the line turn into a smooth curve.  The computer will repeat:
             Close/Join/Width/Edit vertex/Fit curve/Spline curve/Decurve/Undo/eXit <X>:

15.3.4.  If the curve you get does not look quite right to your eye, SELECT UNDO and then SELECT SPLINE. FIT CURVE and SPLINE are similar in function but
