Edit feature and uncheck merge results, it will then create bodies that can be saved as parts.
Assuming that these are seperate bodies in a part file, there are two options that I use. The first is to use the Select Bodies function in the PropertyManager. This can be done when first inserting the Model View of the part, or after the part has been brought into the drawing. I don't know which version of SW you're using, and I believe this feature was new with SW2010.
A second option is to bring the part into the drawing, RMB on it, and choose Drawing View > Relative View. That works in earlier versions. This is used for views other than the standard ones (you will be asked to choose a front face and right face), but there is an option for selecting bodies to display if you don't want to show the whole part in the drawing.
Feel free to ask if you have more questions.
