I just took the front part and extruded it, but I can't work out how much depth to give it. It defaults to 50 pt. What units are pt?
I worked out what the width should be in pixels but obviously pt isn't pixels as it was too long then. It's also not percent.
If working in 72 DPI then 50pt would be 1.76mm
