What is often overlooked is the fact that an inserted xref can in turn contain more xrefs and so on, to several levels deep. If you want to send a host drawing to someone else, you have to be sure you also send all of its attached xrefs. Under certain conditions, the host may load the wrong xref.Īn important point to note here is that the path type is set individually for each xref, so that a single host drawing can contain xrefs with all three types of path.Īs indicated in a previous article, one of the weaknesses of xrefs is that problems can arise if you send a host file to a different user, or if you move it or any of its related xrefs to a different drive or folder, or if you rename an inserted file. No path: The host drawing remembers just the name of the inserted file. This option is not available if the inserted drawing is located on a hard drive different from the host drawing, be it another local drive or a network drive. If the inserted drawing is located in a folder that is not a subfolder of the one housing the host drawing, things can get messy if things change.

The entire folder structure can be moved to a different drive or different main folder without any problems. This works best if the location of the inserted drawing is a subfolder of the one holding the host drawing. Relative path: The host drawing remembers the name of the inserted file, plus its path relative to the host drawing. On the other hand, if any xref is moved to a different folder, the host won't be able to find it. Whenever the host is opened, it will automatically find the correct xref.

This can also point to a network server or it can be a URL to a website.įull Path is usually the safest because it stores the full path for each file. Let's review it, followed by the other two options available in the dropdown list.įull path: The host drawing remembers the exact, full path to the inserted file, from the drive letter on down to the name of the file, as indicated in the upper portion of the dialog box in the figure. It is highlighted in blue, and says Full Path. Observe the Path Type window in the figure. As we saw in Episode one, this is almost exactly like the normal Insert dialog box that appears when we are inserting a block.Īlmost is the operative word here. Next, AutoCAD displays the External Reference dialog box. On the other hand, we can also use the appropriate toolbar button, menu pick, or ribbon panel item. We can also cheat a bit and enter XAttach, which jumps straight to the Attach option of the basic command. The basic command is ExternalREFerences, but the xref shortcut is much easier to type in.

As usual with AutoCAD, there are a number of ways of doing this. Start a new drawing, or open an existing one, and attach a new external reference. At the time we simply inserted the Xref using the default values, but it is now time to go back and look at some of the options. This time we will turn on the Wayback machine, and go way back to the first of the two columns.

In my October and November columns I discussed how to link other drawings into a host drawing using the ExternalREFerence (Xref) command, and how to clip them so that only selected portions of them are visible in the host. That's it! This month's topic! Different locations!
