Normally, surfaces and datum curves are put on a layer and blanked in the drawing. As stated previously, surfaces are used to create solid geometry when you cannot create the solid geometry with normal features. To show the dimensions in the drawing: Show Dim>By Feature and View. There are two ways to ensure all dimensions that drive the model show up on your print. I call up my model, modify the first solid feature and figure out what views I need, then create the views and show the dimensions for that feature or redefine it so the dimensions show like I want them to in the print. This is a good way to ensure you create the proper relationships for a part. After creating the views and showing the dims for that feature, I move on to the next feature, eventually completing the drawing. Another option with a small part is to create your views and show all the dimensions.
