Chimera supports a format for making geometric objects called BILD
described in the Chimera manual:
Below is a 6 line BILD file that when opened in Chimera shows cylindrical
arrows for the X (red), (green), and Z (blue) axes in the style of the
program VMD. I made the axes 20 units long, with radius 1 and cone shaped
tip with a radius of 2.
