This is most likely something basic but I am very new to autoCAD. I have created a fireplace mask and I want to save it as a PDF. In options I changed the layout view to have a black background so it can look as good as it does in model space. However no matter if I try to save it from DWF to PDF either from the model space or layout view, it always goes back to the white background and black 3D object (which looks terrible and loses most of the detail) once it becomes a PDF. I checked options in both Adobe acrobat and CAD but cant find anything. I need one you super CAD gurus to help me out!!! Any help would be greatly appreciated since I am learning autoCAD all on my own. Thank you in advance.
