Doesn't really work that way in Inventor. You can select parts as edges through the browser, then change line type, weight, etc manually. You can still toggle layers on and off but since all outlines use the one layer and same for all hidden lines or reference lines or anything according to your object defaults, there really isn't the need for layer manipulation as in AutoCAD.
If you say what you are trying to achieve I could suggest how to do it in Inventor.
