Hi, I'm having an issue that my shaded views look flat and are raster images when I output to PDF. The views look great in Alibre's DRW, but the PDF looks, well, NOT great (but only the shaded views). Is this a known issue? I did a quick search and couldn't find anything. I tested with Microsoft PDF writer and another PDF creator, I get exactly the same result. See below. Any way to fix this?
