For the 3D Revolve Options in Illustrator, we need to create the front view outline shape of the object we want. It always goes from the center point to the outline of the object. For example, a globe could be revolved by drawing a half circle. I have illustrated a view possibilities in the image below.
Lets start with our push pin. Create a new file. Drag a vertical guide onto the artboard. Select the Pen Tool(P), set the fill color to none, and the stroke to black. Note that you can change the color at anytime later on. Then draw a line, as you see in the image below.
Select the path and open the Revolve Window under Effects > 3D > Revolve.
