// ruler(length, width, [thickness=], [depth=], [labels=], [pipscale=], [maxscale=], [colors=], [alpha=], [unit=], [inch=]) [ATTACHMENTS];

// Creates an attachable ruler for checking dimensions of the model.
// Creates an attachable ruler for checking dimensions of the model. The rule appears only in preview mode (F5) and is not displayed
// when the model is rendered (F6).
// Arguments:
// length = length of the ruler. Default 100
// width = width of the ruler. Default: size of the largest unit division
