PPT Productivity's Slice Shapes feature lets you split a selected shape into multiple shapes in PowerPoint. Select a shape on your PowerPoint slide, then the Slide Shapes feature button. You will be prompted to enter how many copies of the shape you want to insert. The feature duplicates the original shape in multiple mini shapes.

The new shapes added to your PowerPoint slide will fit within the largest height and width boundary of the original shape, in a grid layout. This means if you are slicing a square or rectangle the effect is that the original shape has been 'sliced up'. If you slice a circle, the slice feature will add circles to your page in a grid that aligns to the height and width of the original circle.
