Under "Camera Properites", make sure that the boxes are checked for "Nonrenderable Obects" in both "Hidden Line" and "Draft" menus. Otherwise, they will only show up in Wireframe Mode.
See my (original) note under Tips and Tricks, entitled "Things a Newbie Should be Aware of".
Construction lines are Nonrenderable objects, as are Profile lines, and anything else you use to generate a model, like Centerlines, etc. I suspect they will be missing too, if that is the problem.
