Transform option for Word Art

When I go to drawing tools > format > shape effects > the last option is 3D rotation.

You are looking the wrong place. To find the "transform" option:

Tools → Format → Text Effects → Transform

Change the shape of WordArt

After you insert WordArt, you can change the shape of it by using the formatting choices on the Drawing Tools tab.
