If you’re path is really complicated, AutoCAD may not be able to calculate the path which will force you to use a Full path. AutoCAD has a mechanism used to calculate a relative folder path which allows us to link files pretty easily. The relative path option is probably the most used.

The No path option is the simplest as it requires that the drawing be stored in the same folder as the current drawing. The No path and relative path options are to be used with drawings that you will end up sharing. So far, I haven’t run across a good way to change the path in a bunch of drawings at one time, so if you know one, please let me know. Personally, I have spent a lot of time going through drawings fixing the external reference path. Because the entire file path is included, in order to properly view the files without editing the location, the structure must be duplicated. For example, a reference to a different project or go-by drawing file that you won’t pass on to other people may use a full path. The path will include the drive letter and the entire folder structure down to the file (P:\Projects\Project subfolder\Drawing.dwg). The full path contains the entire file name in the reference to locate the drawing file. The full path type is most suitable for reference files that are specific to your company or location. So, before you attach xref’s you should save the current drawing where you will need to store it. However, if you are in a temporary drawing, the relative path option is not available to you. The options available for path type are Full path, Relative path or No Path. Two in particular can have a big impact on model portability, the reference type, and the path type options. I thought it’d be worth the time to dig into the XREF command options a little more.
