Hi Johan,

I saw this code from you

----------------------------------------------------------------------

using  SolidWorks.Interop.sldworks;
using  SolidWorks.Interop.swconst;
using  System;
using System.IO;
using   System.Windows.Forms;

namespace  ToDWG.csproj
{
    public  partial class SolidWorksMacro
    {
         public SldWorks swApp;
          public IModelDoc2 swModel;
         public string folder;
         public string[] files;
         public string result;

         public void Main()
        {
             FolderBrowserDialog fb =  new FolderBrowserDialog();
            if  (fb.ShowDialog() ==  DialogResult.OK)
            {
                 folder =  fb.SelectedPath;
                files =  Directory.GetFiles(folder);
                  int errors = 0,  warnings = 0;
                foreach (string file  in files)
                 {
                    FileInfo fi = new  FileInfo(file);
                     if (fi.Extension.ToLower() ==  ".sldasm")
                    {
                         //Do  Nothing
                    }
                    if   (fi.Extension.ToLower() == ".sldprt")
                    {
                           //Do Nothing
                    }
                    if   (fi.Extension.ToLower() == ".slddrw")
                    {
                           swModel = swApp.OpenDoc6(file, (int)swDocumentTypes_e.swDocDRAWING,   (int)swOpenDocOptions_e.swOpenDocOptions_Silent, "", ref errors, ref   warnings);
                          swModel.Extension.SaveAs(fi.Name.Remove(fi.Name.LastIndexOf(".")) +   ".DWG", (int)swSaveAsVersion_e.swSaveAsCurrentVersion,   (int)swSaveAsOptions_e.swSaveAsOptions_Silent, null, ref errors, ref   warnings);
                        result += file + "\n";
                           swApp.QuitDoc(file);
                    }
                }
                   swApp.SendMsgToUser2("Files saved to DWG: \n" + result,   (int)swMessageBoxIcon_e.swMbInformation, 0);
            }
          }
    }
}

I'm  new to writing SolidWorks programs and wanted to know how to setup the  dev env. to run this program

I have .NET installed, SolidWorks  2009, visula studio Entp. on my system

I wanted to use this code to launch  solidworks, read in a dwg from an  input dir and save the pdf file  generated using save as to a different  directory

I'm trying  to create a program that would run in the command prompt  as,

genPDF.exe  -i c:\dwgFiles\part1.slddwg -o c:\pdfFiles\

where,

i = input file

o=  output file

I  really appreciate all the guidance and help in undestanding how to  resolve this.

Thanks again

Renni.
