"I'm a bit unclear as to what 'Helvetica' is and how it is being "
at that time away3D don't know it too...
is your font a font generated by Fontexporter ?
if so let's try:
private var font:FontData = new Helvetica();
(don't forget to import the FontData class first:
import away3d.loaders.data.FontData;)
helvetica should be an .as class in your fonts folder,
with a declaration like :
public class Helvetica extends FontData..
if your font in the folder is a .ttf font try:
var font:FontData = TTF.load("assets/Helvetical.ttf",
"abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ,.;:?!-_");
