Insert a new shape into a PowerPoint slide, and you’ll see that it may be filled with a solid color and has an outline by default (this may differ depending on the Theme applied to your presentation). You can remove the fill of the shape as well as the line. In this tutorial, we’ll learn how to remove the line attribute, also known as the outline from a shape so that it only includes a fill without any line. Whatever you do, make sure that you remove either the fill or the line because if you remove both, then your shape will no longer be visible.
