Can someone please tell me how to get the symbol for "therefore" in autocad 2014

It can be done using MTEXT by inserting a symbol.  Start MTEXT then right click where your text would go.  From the flyout menu select Symbol.  The font you need to reference is called appropriately enough Symbol.  Select to copy then paste where your text goes.
