fl.* classes are part of CS4. AS-only projects in FB are usually really small things that use flash.*.* classes.

Flex is a great framework, but sometimes its too heavy and large for certain tasks. To start, I was trying to do a simple animation using only AS3 as described here: http://www.adobe.com/devnet/flash/articles/creating_animation_as3_print.html I have FlexBuilder3, and I don't have CS3 or CS4 Professional. I opened up FlexBuilder, created a Action Script 3 project, and I selected to use SDK Flex 3.1 (the only SDKs I had available were Flex 3.1 and Flex 2.0.1 Hotfix 3) Once my project was created I tried to import classes, but these packages could not be found: import fl.transitions.*; import fl.transitions.easing.*; Do I need to download a separate SDK to make flash work? Or, do I have to buy a whole new application, such as CS4 Professional?
