I have a wiring diagram which I am trying to fill boxes with color to facilitate reading. The boxes have labels and I am only trying to fill the box around the label. I have already filled 6-7 boxes exactly the way I wanted. However, came across one of the boxes where no matter what I did it placed a the rectangle box I created under the box on the sheet. Now I am getting two options. Preserve transparency or fill the box. I do not want either of these options. I want to fill the box retaining what is already on the drawing. I am working from a PDF file opened using PS.
