I am tryin to make a quick wiring diagram to send to customers.  I made some quick parts to represent units and put them in a drawing.  My first problem in the parts will display on top of one and other as i want but then the upper parts will be "hidden" behind the others?  Also when I print/save the drawing half of the parts dont display.  I did a print screen shot and saved it as a .JPEG, hope this helps.
