Working with Graphics You can use rectangles, ovals, and lines to create interesting, complex animations in Flash. Combine them with imported graphics for even greater possibilities. Lesson Overview In this lesson, you'll learn how to do the following: * Draw rectangles, ovals, and lines * Understand the difference between drawing modes * Modify the shape and size of drawn objects * Apply fill and stroke settings * Import bitmap images for use in fills * Select elements and portions of elements * Create simple animations using motion tweens * Group elements * Create masks to hide areas of layers This lesson will take approximately 90 minutes to complete. If needed, remove the previous lesson folder from your hard drive, and copy the Lesson02 folder onto it.   Getting Started First, view the finished movie to see the animation you'll be creating in this lesson. 1. Double-click the 02End.swf file in the Lesson02/02End folder to play the animation. The project is a simple animation that can be used as a logo on a web page or as a preloader, an animation that keeps the viewer's attention while a web page loads. This animation is for Fizzy Drink, a fictional company. In this lesson, you'll draw the shapes, modify them, and animate them. 2. Double-click the 02Start.fla file in the Lesson02/02Start folder to open the initial project file in Flash. 3. Choose File > Save As. Name the file 02_workingcopy.fla, and save it in the 02Start folder. Saving a working copy ensures that the original start file will be available if you wish to start over. Creating Rectangles Flash includes several drawing tools, which work in different drawing modes. Many of your creations will begin with simple rectangles, so it's important that you're comfortable drawing them, modifying their shapes, and applying fills and strokes. You'll begin by drawing the glass for the fizzy drink.
