I have had a few calls about this in the last 2 weeks and while for many of us who have been using AutoCAD for a decade or longer it is easy, for new folks this is an important topic. “FATAL ERROR. THE PROGRAM HAS CAUSED A FATAL EXCEPTION AND MUST CLOSE.” Whether I get an error like this, or the battery on my laptop dies the end result is that the program is terminated abruptly and abnormally (in some cases catastrophically).
It is not always the end of the world. The first thing to do is grab your horseshoe, 4 leaf clover, rabbit foot, and jar of salt….
In the video below I am documenting steps for recovery when we are talking about Carlson Field with the IntelliCAD option. Much of the same information works when using AutoCAD or other Carlson programs such as TakeOff or Survey with the Embedded AutoCAD engine. Because my most recent and most urgent call involved Field and IntellICAD that is where I am focusing.
First let me explain a little about the data. Carlson stores the graphics in a DWG file and this applies to AutoCAD, AutoCAD OEM, and IntellICAD. For each drawing file created you should have a BAK file which is stored in the same location as your drawing file and should be current up to your last save. Beyond that there is an AutoSAVE file being stored based on the AutoSAVE settings specified in the program. This is not always good news for us old guys because one of the first things we often change is the interval of those AutoSAVE files. First check the time interval and make sure it is set to something reasonable (5-10 minutes perhaps, if you are a belt & suspenders kind of person go with every 1-2 minutes).
Now after the graphics we have the data. In Field we have both a CRD file AND a RW5 file. The CRD file contains all of our coordinates and the RW5 has all of our angles and distances and setup information. The video below shows how to verify where this is stored and what you can do with it.
The reality is that upon a fatal crash it is not always bad news. Often times much of what we were doing can be recovered. Take a deep breath, rub your lucky rabbit foot, toss some of the salt over your shoulder, and begin looking at the recovery options shown below.
