PDF files do not create shadings
When creating a PDF file from a Draft, which has shadings in a drawing view (e.g. 300 dpi), the same drawing view in the new PDF file do not include the shading. Which adjustment should be made ?
When i saw your question, started to look at it by myself and didn`t find any of adjustments you asked...every time your drawings goes straight as lines to .pdf, even part environment/render mode give the same results...but, you got alternative solution for this issue. When you are in draft (all colors and shadows included) save it like .jpg (or if you are using win 7, snipping tools/mark your drawing/save as .jpg - win xp: ctrl+c drawing/open paint/ctrl+v/save as .jpg). This .jpg you can import in .pdf straight if you have Acrobat writer or through word2007 directly using save as .pdf command.
Hope it helps :)
