Recovering a drawing using the Map query build in Civil 3D!!!

Hello everybody!... Sometimes it is not possible to open a drawing because it is corrupt. In that case, you might attempt to recover the drawing using the RECOVER command, or by inserting it into another drawing using the INSERT command. However, when these methods are unsuccessful, you need another way to recover the drawing. So at this time I'm going to show you how you can use the Map Query functionality build in Civil 3D and LDT...
