How to get dimensions that are not "Display Dimensions" From Model

I'm trying to write a macro that processes dimensions in our assembly drawings but am having trouble. All the examples I have seen say to get the first display dimension in the view and then use GetDimension on the display dimension. Correct me if I am wrong, but display dimensions are used in the model right? What about dimensions that were added to the drawing manually after the drawing was created? I can't seem to gain access to these. I've tried going the GetAnnotation route with the overall drawing itself and then call GetType on the annotation returned but dimension does not seem to be in that category. Any help would be appreciated, Thanks.
