If you are dealing with 3D graphics in your PowerPoint presentation then you it is good to know that powerpoint lets you edit the SmartArt Graphics in 2D mode (only for editing purposes) which makes easier to edit the text and shape properties inside the SmartArt Graphic.
This can be very handy if you need to edit shapes and text inside 3D graphics. For example, we are showing here a sample after editing OSI Model Presentation in Microsoft powerpoint.
To access this option, you need to select the SmartArt graphic and then look for Edit in 2-D under SmartArt Tools -> Format menu.
