[Chimera-users] Question about tilting a structure in a movie

Hello all, I am a new Chimera user and interested in using the program to create a movie of one of my molecular structures. I have been using some basic commands (turn, rock, etc.) but I would also like to be able to tilt my molecule. For example: tilt forward 45 degrees and tilt back to the original position. I can get the model to tilt by using the command line: turn x 1 45 however, I can't figure out how to make the model return to its original position smoothly. I can use the reset command but that looks a little disjointed. Any advice or suggestions would be greatly appreciated. Thanks, Desiree
