How to apply 3D Annotations?

[KLineDesign]

Hello, I would appreciate if someone would please give very specific instructions on how to apply 3D Reference Dimensions in an assembly model. I currently have an assembly trimmed up (using section view) to see some interworkings. I would like to show several dimensions and annotations to help with the explanation of different proposals. Currently I can add Notes, but I am unable to add dimensions correctly. Any help would be greatly appreciated. Thanks, KLINE

A little clarfication on what I am looking for... I essentially want several dimensions grouped on a particular plane, saved in my model. These individual groups of saved reference dimensions and notes on a single plane I need to be able to toggle to in a Design Review.

Thanks again,

When I need to put some dimensions in an assembly file I do as follows: I start a new sketch; then convert the edges I need to dimension; and add the dimensions as driven. I can then toggle the sketch on and off in the view menu while taking screen shots for a design review.
