Sometimes when working with text you realize that words can only articulate so much. And that's why drawings in Google documents can be useful for diagramming processes in a flowchart or clearly articulating relationship between a groups of ideas. To get started, select Drawing option from Insert menu to see drawing editor. When creating a drawing, shapes menu can be particularly helpful, and whip up something playful or professional in no time.
As with images, you can resize a drawing and even mark it as inline or fixed within a document. You can also copy existing drawing into a document. "First select the relevant shapes in your original drawing, and then copy them using Web clipboard. In your document, open Web clipboard and paste the drawing into your document."
