The Dragon will tell you what to do, just follow it's directions. If you have a issue with this program, make sure you are following the Instructions, and if you still are having the issue, leave a comment about it, I want to make sure it works right. -Thanks!
I made the Femur on Paint, the Dragon is from Scratch. This is for my bone project in science, so thanks to my science teacher for assigning this project, I had fun making this.
