Another question? Tracing a Bitmap Shape

[skipD]

Hello once again..
I must be thick for I keep reading the help file and the tutors but I cannot export from Xara X to X#D (which I purchased) I was with the help of this forum to sping the UN medal but this graphic does not do what I want. I wish to export this graphic to 3D
when I try in Xtreme I traced the image with a black line, then I tried to follow the help file but all I get in 3D is a square block? can you tell me what I am doing wrong..
thanks
