I don't know what Autodesk has done, but Design Review 2012 just doesn't work for plotting. Besides the known 11" x 17" bug, I have run into another one. From Civil 3D 2012, I have a drawing with a color GeoTIFF and a 2-bit raster scan overlaid on top of the GeoTIFF. I have a layout with a border and title block and a viewport with the two raster images set to 100 scale. The printer is set to DWF6 ePlot.pc3. The DWF looks correct in Design Review 2012. (See attachment adr2012_screenshot.png) However, when I send it to our HP Designjet 4000 plotter, the other attachment shows what happens. The color GeoTIFF is scaled and moved while the border and the 2-bit raster image are correct.
Thank you for your question.
Please upload your DWF/x file to this thread for us to investigate in more detail.
