Hello Everyone. I'm new to solid works 2015. To familiarize myself with the software, I decided to work on an individual project. I'm currently designing a pencil. However Ive run into a road block. I want to be able to press the side with the eraser on it and have lead come out the other way. How should I go about doing that? A detailed response would be greatly appreciated. Thank you so much.      Additional:- My assembly currently has an eraser, the body mainly. I need to make a spring to finish it off.
