Ok, this is like infinex's "2D Structure with prespective" except for the fact that you draw the 2D structure in this! Draw your pic, and then press space to see the picture in different angles. WARNING: Don't let go of clicking the mouse once you started unless you are done. If you do, then a line will automatically draw from the point that you let go of to the next point which is created when you click the mouse again. I bet 80% of the people didn't understand what I said, but you will figure it out (probably). Have fun! Must download to work!
