Wmanning, thank you for your tip and I also found another solution for the issue.
For those who has the workflow between SU and AutoCAD,
There are option to check. If you use 2009, Go to Tools-Option in the top menu bar. It opens up the option dialogu box. Under the User Preference tab, in the Associatice Dimensioning category, there is a check box. If you check this option, the issue will be solved. I will post a image.
P.S: I am sorry. I know this is rather CAD issue but I have been frusttrated by the issue for a long time. I think this will be a good tip to whom has the same issue.
