Greetings all, I'm becoming more of a regular here with questions...need to start answering some so I feel like I'm contributing more.

Our facility layouts are done in Solidworks as a simple 2D drawing.  The floorplan shows machines, pallet spaces, pillars, basically everything you'd see looking down on the facility.  Management has asked me to add pretty colors to certain areas to show what each area is.  Rather than a simple box to bound them, or just changing the line colors for entities in that area, they would like the area to have a filled in square of a set color.  However, if I draw a rectangle and give it an area hatch, it overlaps pretty much all other drawing entities.  Is there a way to put that square and the area hatch behind the other entities?  I thought there would be a way to do it using layers, but either I am misunderstanding how to use them or this does not work.  Is there a way in Solidworks to add this area hatch, and then move it behind all other drawing elements, or would I be better off taking the PDF of the drawing into a PDF editor and creating the layers behind that?
