Ah thanks for the tip. Actually for a rectangular preview, I don't even have to create the invisible object. As long I have the coordinates, then using the Export Bitmap - Custom option I can just enter in the corner points where my guidelines intersect. Its still not my most ideal way to do it, so ...

I use guidelines to define my bleed areas and where the printer should cut the final product. Is there a way to preview or view what the output will be of what is inside the area bounded by the guidelines (excluding the bleed area)? Perhaps some function to pre-define a view/preview area? Thanks, John
