Apologies in advance for the potentially-newbie question – I haven't used Illustrator very much and may not be using the right terminology for things.
I have a group of shapes that I've applied a diagonal-hatch pattern fill to:
I would like to export a Postscript file containing the line segments comprising the pattern, so that I can plot it on my HP 7475A pen plotter.
For the plotter to be able to plot the resulting Postscript file (after converting it to HPGL via
pstoedit), it needs to contain exactly the lines on the screen. It can't have just the polygons with a pattern specified (the plotter doesn't understand that and ends up plotting just the polygons) and it can't have mask layers specified in the file (the plotter ends up plotting all the lines unmasked).
In other words, I'd like to "finalize" the currently-active mask and export just those portions of the lines that are currently being shown.
I've tried Object → Expand and then Object → Clipping Mask → Release. I then get all of the lines that were previously masked (see below). I've tried all of the Pathfinder options, Object → Flatten Transparency, etc, and nothing seems to do what I want.
