Need some help regarding flash animations

[FONT=Arial][SIZE=2][FONT=Arial]My problem is I want to create a flash with some objects that user can modify them in to some shape or object. For eg. Say I have some wheels, bars and connectors displayed in my flash and user can design a cart using them. [/FONT][/SIZE][/FONT]
