1. Select LINE Tool , shortcut key \ ( back slash )
2. Draw a line, normally it will be a narrow line.
3. Ctrl + F10 or Window -> Strokes , open strokes panel

Step 1 : Firstly I have drawn a line which has no strokes. It shown below. But when you apply weight (thickness) to it, the Strokes panel components like CAP, Corner, Align Stroke becomes active. To draw strokes you need a line, so I have selected the line tool and drawn a line. It has no stroke. But still it is a line.

5. Now our job will be to change its width… to make it thicker.

Now I am going to apply some thickness to it. Now I am going to apply 6pt stroke to it. You can change it to any thickness you want. But if a thicker stroke applied on the line you have just drawn, you will be able to see the actual path and thickness imposed to it. Actual path is always shown in blue color.

Here you can assume the line as a path, and stroke indicates the thickness
