Important Options
Working with outside consultants can get ticklish, you need to protect the integrity of your drawing files. Audit every drawing that comes across your desk from an outside resource. I also look for the following options and set them accordingly:
ISAVEPERCENT
Can access this via Options on the “Open and Save” tab. This variable determines the amount of wasted space tolerated in a drawing file. The value of ISAVEPERCENT is an integer between 0 and 100. The AutoCAD default value of 50 means the estimate of wasted space within the file (can you say ‘fragmented file’) does not exceed 50 percent of the total file size. Wasted space is eliminated by periodic full saves. When the estimate of wasted space exceeds 50 percent, the next save will be a full save.

If ISAVEPERCENT is set to 0, every save is a full save. It’s interesting to note the defualt value of this variable in Civil 3D is 0 – therefore your drawing file is entirely re-written each time you save.
Full-Time CRC Validation
Specifies whether a cyclic redundancy check (CRC) should be performed each time an object is read into the drawing. CRC is an error-checking mechanism. If your drawings are being corrupted and you suspect a hardware problem or a software error, turn this option on.
Can access this as well via Options on the “Open and Save” tab.
