How to create shape that follows camera movement

Question

Hi
I am trying to create a little axis representation on the bottom of the canvas that would be fixed in position relative to the camera and the axis. (i.e. if camera moves or rotate, the axis representation will stay at the same place and rotate accordingly). What is the best way to do this ? Do I extend the Camera/Mouse class and tell it to update the transform group of the axis shapes whenever it moves ? Does anyone have a example of how they did it ?
Thanks, Dave

Julie,
To get something that resembles a straight pill (or a capsule) as the one you describe, you may:
1) Create the outer rounded shape and split it into two: one on top with the stroke, one below with the solid fill corresponding to the colour adjacent to the stroke;
2) Select the filled path and Object>Path>Offset Path, using a negative value that is half the width less a suitable small amount (1pt or something);
3) Change the fill of the small inner path to a paler grey or white;
4) Select both the filled paths and Object>Blend>Make (with Smooth or a suitable number of steps in the Object>Blend Options).
To easily get something that is more like a round pill, you may apply horizontal gradients to the paths in the blend, along with a suitable number of steps.
With a new version, you may also use the new 3D features.
