AcApLayoutManager *pLayMan = NULL;
    pLayMan = (AcApLayoutManager *) acdbHostApplicationServices()->layoutManager();
    //get the active layout
    AcDbLayout *pLayout = pLayMan->findLayoutNamed(pLayMan->findActiveLayout(TRUE),TRUE);
   
    //get the PlotSettingsValidator
    AcDbPlotSettingsValidator *pPSV =NULL;
    pPSV = acdbHostApplicationServices()->plotSettingsValidator();
    //refresh the Plot Config list
    pPSV->refreshLists(pLayout);
   
    //get all the Plot Configurations
    AcArray< const char * > mDeviceList;
    pPSV->plotDeviceList(mDeviceList);
   
    acutPrintf("\nPlot Configuration List :");
    int nLength = mDeviceList.length();
   
    for(int nCtr = 0;nCtr < nLength; nCtr++)
    {
        acutPrintf("\n %i) - %s",(nCtr + 1), mDeviceList.at(nCtr));
    }
