Different way of using Follow Me Command in SketchUp
1. Identify the path for your extrusion.
2. Draw a face or profile that you want to follow the path. Make sure that this profile is perpendicular to the path.
3. Select the Follow Me tool
4. Click and drag the face that you created along the path. As you drag, touch the mouse pointer to the path you're following. SketchUp highlights the path in red, as shown in the figure. If your starting edge is not touching the profile, Follow Me starts extruding at that edge, not from the profile to that edge. If you need to start over, press Esc.
5.Click to complete the Follow Me operation when you reach the end of the path.
