I have finished drawing a 3D of a building using the combination 3dsolids, 3dfaces and exploded text and extruded to certain height. I am using AutoCAD 2012, set up to shaded with edges, setup the dwg to pdf.pc3 to 12oo dpi. When I plot the drawing, the output seems to be pixelated when viewed by adobe reader. Plotting to a colored printer seems to be okay. How can I plot 3D drawing to pdf with smooth edges?
Are you using a visual style or Plot Shademode other than 2D Wireframe? You may need to open Visual Style Manager. Select the visual style you are using. Set the Edge Settings > Show, change it from Facet Edges, to use Isolines. The Facet Edges, looks great on screen, but causes the plots to have poor resolution.
I have tried almost all of the options and combinations in the Visual Syles, and still get the same pixelated pdf.
I even adjusted the pdf setting to maximum 2400dpi. Plotting to a 300dpi printer is okay
Is 3D plotting printing the drawing displayed on the screen and not the drawing itself?
