Then you slowly add the flesh, blood vessels, corpusels, and myriad of other assorted body parts that are attached to a skeleton just as you would color, distort, and modify a graphic. The path determines the fate of an object's shape, so it's important to know about the tools that shape this fate. The pen is one of your closet allies in Illustrator. It creates straight lines as well as those beautifully arcing curves that you could only dream of calling your own. The anchor selection pointer looks like the regular pointer except it's hollow in the middle.
Anchors are points that make up a path.
A square has four anchors while a pentagon has a five anchors and so on. For every corner, Illustrator assigns an anchor point. So, a circle is really just a square with four curved sides. Once you have an anchor point selected, you can edit the shape of the path that is traveling through the anchor. You can make a 90 degree corner on a square turn into a fat, popsicle stick end, or you can change an anchor on a circle into a sharp, jagged corner.
