Plot Style file location.I am trying to locate Plot Style file.If needed, close and reopen AutoCAD to refresh the plot style tables list in the PLOT dialog drop down. In the Properties palette, select a plot style from the list of available plot styles. Tip: You can also right-click in the drawing area and then, click Properties. Click View tab Palettes panel Properties. Copy all CTB and STB files into this folder. Select one or more objects whose plot style you want to change. On the Begin page, you can choose to use an configuration file (CFG) or plotter configuration file (PCP or PC2) to import pen settings, base the new plot style table on an existing plot style table, or start from scratch.
