new database, readdwgfile, insunits

I am using this code to rename dwg files from a third party. The insunits are set to "2" (feet). I thought I could change the units at the same time, but it is not working.

We work in metres (insunits = "6").

string dwgname = "dwg from third party"; 
string newname = "newname.dwg";
string savepath = "c:\\temp\\";
using (Database db = new Database(false, true))
{
  db.ReadDwgFile(dwgname, FileOpenMode.OpenForReadAndWriteNoShare, false, "");
  db.CloseInput(true);
  using (Transaction tr = db.TransactionManager.StartTransaction())
  {
    Application.SetSystemVariable("INSUNITS", 6);
    tr.Commit();
  }// using tr
  db.SaveAs(savepath + newname, DwgVersion.Current);
}// using new database

What is the correct procedure?

The answer is replace "Application.SetSystemVariable("INSUNITS", 6)" with "db.Insunits = acdb.UnitsValue.Meters;"

I should have searched a bit further.

Hi,

Try doing simply like this:

            using (var db = new Database(false, true))
            {
                db.ReadDwgFile(dwgname, FileOpenMode.OpenForReadAndAllShare, false, "");
                db.Insunits = UnitsValue.Meters;
                db.SaveAs(savepath + newname, DwgVersion.Current);
            }

Yes - thanks. It occurred to me (too late) that I didn't need a transaction to set an application system variable.

In my own words - "SEARCH FIRST" and use the correct search parameters.
