There is a line button and I was able to draw all kinds of squiggly things with it. I even used it to sign my name, but I just could get a straight line. Can you believe it is as easy as clicking one button.
In PatternCad on the right side under Patterns, click on the Draw button. Then select Line. See the button with nodes on it under Node Spacing. It is selected by default, click on it to deselect.
Now draw a line.
Yes, it really was that easy.
