Thanks for your response. Sorry but I did not have time to get back to work on drawing until now. I tried both places to activate the callouts: -options-> and the window screen's left bottom corner. Neither of them worked. By the way, -properties bar for door and window does contain dimensions but it does not contain "callouts" activation button. The dims is activated in my drawing. My problem is only one side of the wall, which is the south side/frontal exterior wall, does not display callouts while every other wall, exterior or interior, does. I wonder if there is something I did to this south side of the walls that could somehow turn the callouts off. I hope some one knows what that may be. Jing

You are right, Lyle. The callouts on that particular wall was unchecked. But Patricia's image helped me to notice and check the wall's properties first. You guys are great. Thanks a lot. Jing
