I see...
Dear ockham,
You know, I made my model 3 part.
It is a example like hand + forearm + shoulder.
Because I need to transform each part.
But, the txt file - you give me, can tansform only one part. (top)
So, If I made it like hand + forearm + shoulder, I can not handle each part.

Dear kuroyume0161,
Thank you for your help.
You teach me how can I make it group.
I am under indebtedness to you.

So, I don't solve it yet.
Is there any way to remove the ugly line?
Would you help me?
Please...
