3d bezier
curves in 2007
Why?
Shows you how to use PowerPoint's drawing and 3d tools to
save time and use PowerPoint's own editing and creation tools.
So you know where we are heading, here is the example:

If you feel
uncomfortable with drawing lines and curves, I suggest you check out
Echo Swinford's excellent tutorial on bezier curves.

Now, on with the job!
First, start by adding a rectangle.
![drawn rectangle](2007_images/2007_bezier_curves_01.jpg)
Give it a 3d layover with the Format tab of the Ribbon| Shape Effects| 3d
Rotation| Off Axis 1 Top.
![](2007_images/2007_bezier_curves_02.jpg)
Right click on the shape and select Format Shape.

Give it some width and height for the top of the shape. Note this is a
"Modeless" dialog box. You can keep it open while you work!
![powerpoint 2007 3d format](2007_images/2007_bezier_curves_04.jpg)
Select the Format tab of the Ribbon (when the shape is selected), the Edit Shape
button| Convert to Freeform. You can now add edit points to the shape.
![powerpoint 2007 convert to freeform](2007_images/2007_bezier_curves_05.jpg)
Right click on the shape and select Edit Points.
![add points to free form](2007_images/2007_bezier_curves_06.jpg)
Right click on the middle, top and select Add Point. Do the same for the
centre, bottom of the shape.
![add point to shape](2007_images/2007_bezier_curves_07.jpg)
You can see the shape result with a point at top and bottom added. Now select
each centre point and drag it down. Notice that while you are editing points,
the shape converts temporally back to a flat 2d one.
![drag each center point down](2007_images/2007_bezier_curves_08.jpg)
Add trees (clip art) and rivers (lines) to taste!
