Are you putting the drawing in the same file that contains the model? Or are you using the "master model" method and placing the drawing in a separate part and then adding a reference set from the model?
Here is a Help topic that explains the difference between the two methods for creating a drawing:
Once you finish reading the topic, look at the list of links on the right side of the page. Those links will take you to examples that show you how to create drawings using the different approaches. We recommend that you place the drawing in a separate file, that way only the "Model" reference set is used to create the drawing, and all the other extraneous objects do not appear in your drawing view.
Both answers are correct, but kind of like the story of the description of the elephant.
The easiest way to control what is displayed in the drawing is the Show and Hide command, and for me, the easiest way to get to it is on the right end of the Top Border Bar. You can turn off objects by category, such as datums, sketches, etc.
That being said, if you have your drawing in the same file as the part model, turning things off in Drafting also Turns them off in Modeling. I personally like to keep the first datum coordinate system visible in Modeling, because that is a statement of design intent of the origin of the part.
The way to create the drawing in its own separate file is to use the New command to create a drawing file, and select your model file as the "Part to create a drawing of."
If you just change applications from Modeling to Drafting, you are creating the drawing in the same file as the model.
