You'll need to create another model to represent the Line of Action. Once you've done this once or twice, you'll be able to just load up a previous line of action and modify it (either in a new model or in Muscle motion).  But for now you'll have to make one from scratch.

Create a new model.  Name it 'Line of Action'.  Open that model window.  Go to the side-view.  In this window, lay out a six-point spline, any old place.  You'll be placing the spline more carefully in Choreography, so don't worry where it goes now.



Now drag this model into the Choreography.  Make sure that it's translate setting is at 0,0,0.  Go to the side-view in choreography.



In the Project Workspace, select the Shortcut to Line of Action. In the mode-bar, click on the Model button.  This will show all of the points in the Line of Action, and allow you to modify the base model right here in the choreography.



Click the first point of the spline and drag it to the joint between the Torso and the neck.




Click the third point of the spline and drag it in front of the pelvis where the torso-neck joint will end up at the bottom of the bow.



Click the second point of the spline and drag it up to about the halfway point, then up and out a little to give a natural looking
curvature.



Click the fourth point of the spline and drag it near the third point, but probably a little bit back.  You don't want the movement coming up out of the bow to be a perfect reversal of the movement going into the bow.  That would be symmetric and look artificial.



Click the fifth point of the spline and drag it near the second point, but again a little bit off-line.



Click the sixth point of the spline and drag it near the first point.

Now you have the line of action clearly marked.  I promised you that you would be able to make the model follow that line of action.  Just click to the next page to find out how.
