foreach (string item in splitText)
{
double numericValue;
if (double.TryParse(item, out numericValue))
{
totalCfm += numericValue;
}
}
}
}

// Create new text entity with the total CFM
Point3d insertPt = new Point3d(0, 0, 0); // You need to define the insertion point
using (DBText totalTxt = new DBText())
{
totalTxt.TextString = totalCfm.ToString();
totalTxt.Position = insertPt;

BlockTable bt = tr.GetObject(db.BlockTableId, OpenMode.ForRead) as BlockTable;
BlockTableRecord btr = tr.GetObject(bt[BlockTableRecord.ModelSpace], OpenMode.ForWrite) as BlockTableRecord;

btr.AppendEntity(totalTxt);
tr.AddNewlyCreatedDBObject(totalTxt, true);
}

tr.Commit();
}
}
}

i am having above code to create the automate calculate the total cfm.

Example ; 1000 CFM and 2000 CFM = 3000 CFM
}
