Once you have the auto shape on the slide selected, make sure you have the drawing toolbar out. It should appear at the bottom of the screen. If you don't have the drawing toolbar out, choose View --> toolbars --> drawing. The last button on the right of the drawing toolbar is 3d styles. click on that button to see a bunch of 3d styles. There is a text button within the 3d styles button called 3d settings. click on that and you can specify how much you want the 3d object to rotate, whether you want wire frame or a bunch of other settings.
For anyone who said that Powerpoint does not have 3d options, you should not answer when you do not know the program. That has been in the program since at least powerpoint 97.
Yeah, but the majority of people use PowerPoint at work and don't want to finance buying all that amazing software.
I found the 3D icon on the tool bar but found all the functions in greys which don't do anything when you click on them.
Just chose a 2D shape first, a square for example and once that is on the slide all the 3D shape options turn to colour and you can choose depths, colours sizes etc.:cool:
Wow - for simple shapes like rectangles and such you DO NOT need another program. Just go to the insert tab - select a simple shape there (say a rectangle). Draw the shape on the slide. Right-click on the shape you drew. A window will pop up - select the "format shape" option at the bottom of the list. A new window will open that lists two options - 3D format and 3D rotation. Select the 3D format option and play with the settings to get a bevel, or a bunch of other 3D effects on your object. Then try out the rotations to angle the object on x, y or z axis.
