By the way, when you set it to “0” – you will loose all of your layer ON/Off settings for all xrefs, not just the one that was not working right.
Reference drawing layers can be modified in the parent drawing and changes to color, linetype, and other properties are maintained as long as the system variable Visretain is set to 1.
When you attach xrefs to a drawing, the program periodically checks whether the referenced files have changed since the last time the xrefs were loaded or reloaded.
The XREFNOTIFY system variable controls xref notification.
For compatibility with previous releases and fr logical reasons, such contextual fields in blocks and s are not updated when you insert them in a drawing - instead, the field always displays its last saved value.
If you open the file references palette, you will see warning that the files are not found. If your project has several folders, then add them all.
It’s useful when you need to take drawings produced from multiple different sources and integrate them into a master drawing set.
Sketch Up has a similar capability, and is even more powerful in some respects.
However, sometimes it’s not easily because there could be many files and folders. It will work for files with relative and absolute path.
Or they may be on a location that you can recreate. And this trick will not change the original path definition.
In Auto CAD, the XREF isn’t copied into your drawing, it’s just linked to it.
Although you’re placing a copy of the imported file into Sketch Up, you have the ability to update it.
Please forgive me for being lazy, I don’t even give the files appropriate name and just use Auto CAD default file name when saving. For example: if Project has sub-folder arch, struct, and mep, you have to add the subfolders too.
You can try to move those files to match the location, or try to redefine each file’s path. Now open your file, all the reference files path will be resolved!
It’s also helpful for managing a large number of scenes in a project.
If you’re familiar with Auto CAD, you might know that you can link multiple drawings together using an XREF.
