I'm using AutoCAD Mechanical 2009. I am in the process of setting up a style based plotting file (stb). When I pull up the layer manager dialog box, there is no plot style column. I went to the Tools->Options->Plot and Publish Tab->Plot Style Settings... and selected the "use named plot styles" button and selected my stb file. I've also gone through the PSTYLEMODE command to make sure it was set to "0". It was set at "1 (read only)", but I proceeded with the PSTYLEPOLICY command and set it to "0". Now the PSTYLEMODE reads "0 (read only)". In the Page Setup Manager dialog box I changed the plot style to the appropriate stb and applied it to all layouts with no results as to the problem I mentioned earlier. I'll continue to search for solutions, but if someone could help I would really appreciate it.
