I think you'll just have to make do with the picture environment. But one can get it to do some interesting stuff... for example, http://physicsforums.com/showpost.ph...&postcount=300  Quote by Perturbation Is there a latex command for Feynman diagrams or contractions in QFT (the lines joining operators to denote propogators and things)? Anyone? They would be kinda useful.

Recognitions: Homework Help I am not familiar with drawing in LaTeX, and I just wonder where I can find a short tutorial on this topic. I think it should also be added to the first page of this thread, so that someone new to LaTeX can learn how to draw. It's just my 0.02.
