I have explained the basics of formatting shape outlines in PowerPoint 2010. Now I take you further ahead to explore more advanced options for all line formatting characteristics like weight, dash style, arrow style, gradient lines, etc. I cover each of these aspects in individual tutorials — this particular page explores how you can change line weight to make the outlines thinner and thicker — I also cover compound lines such as those that encompass double or triple lines. Weight is the thickness attribute of the shape outline. You can change the weight all the way from a hairline thin line to a chunky thick line.
