Inventor API - The wrong position of bodies when use COPY OBJECT in Inventor

[Khoa_NguyenDang]

Hi all guys 

I am coding a tool to copy the solid bodies form this part to the other part. 

But when i start my code, it work. But the problem is the position of the copied solid bodies is not the same with the origin part (As picture i post) 

I thicnk may be when i use the copy method code it doesn't know what the assembly i base on to do the copy 

Do anybody met this problem before, hope someone can help me.

Thank you so much !
