what is difference between line and polyline in autocad?The lines and polylines are two objects with different properties in autocad. Through the Line command, every time you click, the part between two points is an independent unity, but the part between the first point and the last point consists of multiple separated independent unities.
You can select one line among them to edit. However, through the Polylines command, they are always a unity which cannot be separated. You can only operate the whole unity when executing attribute edition (e.g. picture 1, when specify object, what the line specifies is only a part of it , while the polylines is the whole of it.) The Line command can only be used to draw lines and it is easy and simple to operate. But, through the Polylines command, not only can you draw lines, but also you can draw arcs, besides, you can execute relevant operations [ Arc/Close/Halfwidth/Length/Undo/Width] to the menu.
You can also close it or edit the lineweight etc. e.g. picture 2, you can draw a polyline with changing-lineweight lines and arcs.
