In the last post, I showed you how to “build” elements of your presentation to help capture the audience’s attention and to increase comprehension. A couple of the examples in that post used devices (a car and a UFO) to deliver an object to the slide. This post extends this idea by using construction equipment to “build” your story.
Here’s an example:
Here an earth mover pushes a substantial block labeled “integrity” into place, presumably to form the foundation of your company’s value proposition. Additional animations might introduce other layers or components.
As I have done before, I used standard PowerPoint shapes and a clipart image from the web to create the machine:
I pasted the clip art image onto a slide and overlaid several standard shapes (Rectangles, Rounded Rectangles, Triangles, Ovals, etc.) to create a simplified version of the machine. I lightened the image for better contrast and used different line colors to help keep track of the component shapes.
I developed this technique to make original graphics easier for users who are not artists or who are not skilled with other drawing techniques. You’re welcome.
I also occasionally use Merge Shape tools to create new shapes. For example, the knobby tire outline is a 32-pt Star (red in the diagram above) with the points cut off by Subtracting a Donut shape (blue).
Here’s the earth mover with color added:
The machine consists of four Groups: the body, the two wheels and the blade assembly. The blade assembly is in front of the wheel. Each of these is animated separately.
The foundation block (the “load”) is a Rectangle containing centered text in an impressive font:
The Rectangle is filled (Picture or Texture Fill) with a marble texture. I added a 3D Format/Front Bevel/Cross for the edge treatment. An Angle bevel and gold fill completes the text. (If you need more help with bevels, etc., there are tutorials available on the web. indezine.com is a consistently good source for tutorials.)
Here’s the layout for the animation showing the starting and ending points for the animation steps (click on the picture to enlarge it):
- Like a mystery writer, I started at the end by placing the load at the center of the slide.
- I placed the machine elements next to the load.
- I created a ruler with units equal to one quarter of the circumference of the wheels. The circumference is about 3.14 times the diameter (remember?). I set the ruler at the front wheel’s center and extended it left to a point where the machine and load are off the slide to the left. This establishes the starting points for the elements.
A distance increment of 1/4 the circumference is equivalent to a 90 degree rotation of the wheel. Using this increment simply makes it easy to calculate the Spin animation for the wheels.
In creating the animation, I used the Animation Painter to minimize the number of times I had to create identical effects on different objects – the parts of the machine are separate but move together. This may become clearer below.
The Animation Painter is a tool that allows you to copy the animation effects of one object to a second object. However, the tool has a couple of properties that make it less than perfect:
- The tool applies to objects rather than effects. That is, you can’t select individual effects and copy them.
- The tool replaces all the animations of the second object rather than adds to them.
Here’s the first step in animating the earth mover and the load:
This is a Motion path/Line/Right effect. I accepted the default Smooth Stop/Start settings for the motion path (more about this later). Next, I edited the default motion path to set the end point at the load “target” location (the red rectangle).
To edit a Line motion path, select the path and move the start and end points (red and green dots). To preserve the orientation of a Right/Left/Up/Down path, hold down Shift while moving the point.
Using the Animation Painter, I copied the motion path to the earth mover body. Here’s the result:
Since the motion paths are identical, the two objects will move together and end up in the same relative position. This is much easier than drawing the path for the body by hand.
Next, I added the path that causes the body to return to its original position. This a Line/Left path with the end points edited. In particular, the starting point is moved to the end point of the first “entry” motion path and the end point to the start of the first path – here’s what this looks like:
The begin/end points of motion paths will “snap” to other motion path points. In this case, this is convenient since I want the paths connected. In some cases, the “snap” is a nuisance.
The two motion paths are now copied to the blade and the wheels. Here’s the result:
During these steps, you will have to re-order the effects in the Animation Pane to get the right result. Here’s the Animation Pane at this stage:
The first group of effects move all the parts to their first positions and the second group moves the parts back to the left, except for the “load” which is left in the center of the slide. All these parts move together exactly since they have identical motion paths.
Notice that the objects have meaningful names rather than the arbitrary default names assigned by PowerPoint. You can rename objects in the Selection Pane. This is extremely helpful for animations like this (and for providing examples for blogs).
The next task is to apply rotations to the wheels. I applied 720 degrees (2 rotations) Clockwise Spin to the front wheel; this corresponds to the distance traveled as the machine moves into the slide. I also added 720º Counterclockwise Spin to the front wheel corresponding to the exit of the machine.
A couple of notes about the Spin animation: first, the Effects Option Pane has an Amount pulldown where you can set the amount and direction of the Spin. In my example, 720º (Tw0 Spins) happens to be one of the pre-set options:
If you want to set a value that is not one of the pre-sets, you can enter it in the Custom field. You must hit Enter after the value in order for the amount to “take.” This is unusual behavior.
Second, the Spin options include Smooth Start/End like a motion path. However, the default Spin does not include these options. So, in my example, I synchronized the rotation and the wheel travel and by setting the Smooth options to match the motion path. If you use motion paths With other effects, the Smooth options will likely not be available.
The final step is to apply the Spins to the rear wheel (using the Animation Painter) and arrange the order in the Animation Pane:
Notice that the order of steps in this process is not arbitrary – it is meant to allow you to use the Animation Painter to avoid having to enter each of the effects separately. In addition, using the Animation Painter to copy motion paths is useful when a group of objects must move together (that is, in a fixed relative position). Doing this “by hand” can be a little fiddly. So, the Animation Painter is not so bad after all.
I have gone into some detail in this post so I’ll have to include some more construction examples in my next post. As usual, if you would like a free PowerPoint file containing this example, use the form below (see this page for details on the free files I provide):
