Excerpt/Capsule: Learn about open and closed Motion paths in PowerPoint 2010.
Motion paths may be paths on which slide objects animate, but for all other practical reasons, they are essentially just ordinary paths (or lines) that have curves, points, etc. If you are familiar with the drawing tools in PowerPoint (Line, Curve, Scribble, and Freeform) -- or if you use a graphic illustration program like Adobe Illustrator or CorelDRAW, you know that paths can be either open or closed.
A circle is a good example of a closed path, whereas a curve is an open path -- look at Figures 1 and 2 to view some samples of open and closed paths respectively.

So, how is the concept of open and closed paths relevant to motion path animations in PowerPoint?
This may not be terribly obvious but any animation that plays on a closed motion path gets back to the original starting point of the animation -- thus the starting and ending points of such an animation are the same.
On the other hand, animations that play on open motion paths have distinctly different starting and closing points -- examples of these are animations that play on a line or a curved path from one part of the slide to another.
If you know how to edit points of paths using PowerPoint's capable drawing tools, you can easily convert open paths to closed, and vice-versa. Even if you are not too familiar with the drawing tools, you can quickly convert an open path to a closed one, or the other way around using the options that we explain next.
Follow these steps to get started:
- Launch PowerPoint 2010. Most of the time PowerPoint will open with a new slide in a presentation -- PowerPoint 2010 users can change the slide layout to Blank by selecting Home tab | Layout | Blank. Now, access the Shapes gallery, and then insert any shape on the slide. Thereafter, duplicate the shape so that you end up with two similar shapes.
- Apply motion path animations to both the shapes. For the first shape, add a closed motion path such as a Pentagon; for the second shape, add an open motion path, such as an S Curve 2, as shown in Figure 3. Alternatively, just download this sample presentation. Play the presentation, and observe the animations. Press Esc key on your keyboard to get back to Normal view.

- If you closely observe two motion paths in Figure 3 above, you will find that the Pentagon has only one arrowhead (the green one), but the S Curve 2 has two arrowheads (green and red). This is PowerPoint's way of telling you that the first one is a closed motion path, and the other is an open path -- closed motion paths show only one green arrowhead whereas open motion paths show both red and green arrowheads.
- Select the shape that has the Pentagon motion path animation applied. Then select the motion path, and carefully right-click the dotted line and choose the Open Path option from the contextual menu, as shown in Figure 4. The immediate result of choosing this option is that you will now see both green and red arrowheads in this motion path (see Figure 5).

- You can now right-click the motion path again, and choose the Edit Points option from the in the resultant contextual menu (refer to Figure 4 above). You'll immediately see vertexes on the path, as shown in Figure 6. You can now select any of these vertex points and drag them around to create something that does not resemble a Pentagon anymore! We'll cover the editing of these vertex points in more detail in a future tutorial.

- Click anywhere on the empty area of the slide to exit the Edit Points mode.
- Now, select the other shape on the slide, and then select its S Curve 2 motion path, as shown in Figure 7. Carefully right-click the dotted line and choose the Close Path option from the resultant contextual menu (see Figure 7 again).

- This will result in a segment being added to your motion path that connects the closing point back to the start point, as shown in Figure 8. Note that you no longer see two arrowheads, but just the green one (compare Figure 8 and 7).

- If you don't fancy the straight line that PowerPoint adds to close the path, you can right-click the motion path and choose the Edit Points option in the resultant contextual menu. Thereafter, click anywhere in the line segment (make sure you don't click a vertex point). This adds a new vertex at the clicking position. Now, drag the vertex down or up to create a curve from the line. Similarly, you can add more vertexes and bend the line segment to meet your requirement. In Figure 9, you can see the edited line segment that looks smoother and more organic (compare Figures 8 and 9).
