Hi @Anonymous,

I am sorry but I might have misunderstood your question. Imageattach is the command in AutoCAD. Your question though seems to be more a 123D one.

If so, I don't have much experience with that product and I am not sure I can help.

Please walk me through what you are trying to so I can better understand for what you are looking.

As I understand it, you are using 123Design but want to get it into AutoCAD?
