Show 3D Model Axes
To show the X, Y and Z axes of a given 3D model use the “show axis” command for example:
d is a dragon
d.show axis x y z

You can show one or more axes but they have to be written in the right order for example:
d is a dragon
d.show axis x
Will show only the X axis
d is a dragon
d.show axis y
Will show only the Y axis
d is a dragon
d.show axis y z
Will show the Y and Z axes
