I am trying to use enumeration with respect to tolerance types.  My Macro looks about like this:

using SolidWorks.Interop.sldworks;
using SolidWorks.Interop.swconst;
using System.Runtime.InteropServices;
using System;
using System.Diagnostics;
namespace Rename_And_Export_Dimensions.csproj
{
     public partial class SolidWorksMacro
     {
          public SldWorks swApp;
          
           public void Main()
          {
               swTolType_e Tol = swTolType_e.swTolSYMMETRIC;
          }
     }
}

Why does this fail?
