How to add a polyline?

Press F3 (ADD_POLYLINE). In this dialog box, the initialized polyline width is taken from the previous selected polyline side. When you simply click on a polyline side, FreePcb-2 remembers its width. Then, when you open this dialog box, that same width value will show by default. If you want to create a non-closed polyline, select the OPEN type; if you want to draw a filled area, check the CLOSED checkbox.
