xref layers still show after detatching

I often have that problem. It's not only that the xref's layers continue to show in the list of layers, but also that the xref itself continues to show in the list of xref's. What seems to be happening is that Bricscad doesn't recognize that the xref has been detached (but other programs do recognize it, and don't include the xref or its layers in their listings).If I try to detach one of these problem xref's in Drawing Explorer, nothing happens. The xref remains in the list. If I try to detach it using the old -Xref command, I just get this message:1 reference found for detach.0 references detacheded.I'm using v8.2.12, but this problem has persisted through several upgrades.I experimented a little just now: I opened one of the problem files in Bricscad v7. The xref showed as still being attached, and was easily detached in v7, and didn't show when the v7-saved file was re-opened in v8. So this is could be a workaround in some cases. But in the case of the other problem file I tried that with, v7 wouldn't open the file. It gave this error message as soon as I selected the filename (before clicking again or clicking on "Open"):Warning: Error was found during open. We recommend that you close this drawing and run DDRECOVER on this one.I can't replicate the problem in a file that I create. It only happens with files that I get from a consultant, but it happens both with xref's already attached and with new xref's that I attach. I assume it's because something is corrupted in the file when I receive it -- something that throws off Bricscad v8.

I have seen this also. In my case I attached the xref again then removed it and all was ok. I have not tried hard enough to see if there is anything repeatable so I have not sent in a support request on this.Greg

Can someone please file a support request and attach a set of drawings that is known to trigger the problem, we will be glad to investigate and solve this issue.

Hello,While you fix this it might be a good idea to look into something else, when Bricscad displays refferences it is impossible to distinguish among master and and slave refferences which are pulled because they are nested in a master refference, it would be nice to have a means distinguish among master and slave refferences and even a way to have a check item where you can select to show only master or both master and slave refferences, kind of what you do with layers where you have a menu option that allows you to display only drawing layers or also layers from refferencesA really nice way to see this would be to have the master refference first and then every nested/slave refference indented a couple of characters depending on the level of nesting, one level=2 blank characters, 2 levels=4blank charactersBest Regards,Jose

I have the impression we are talking about some slightly different - though closely related - problems here.Some investigation learned that the Drawing Explorer does not update the layer grid after an xref is attached or detached.So if you detach an xref and then select 'Layers' in the 'Open Drawings' tree, the xref layers are still displayed, although in fact they are no longer there.If you close and reopen the Drawing Explorer, or select another drawing in the tree and then come back to the previous one, the layers are no longer displayed.We will provide a fix for this as soon as possible.Marc: This may explain part of your problem, but it does not explain why the layers still appear after the purge command. This I could not reproduce. Could you enter a support request with drawings that illustrates this issue?Anthony: Can you please forward us those files you mention, where xrefs still show in the list of xref's after they were detached? We would be happy to investigate this further.Jose: When you click the 'Tree view' button while viewing xrefs in the Drawing Explorer, the hierarchy of the xrefs will be shown in a tree.

Thank you Antony, I did'n know about that support request. I put it on my name and I will follow it up. This problem looks different from the others, in that the main problem here seems to be that the xref is still shown after detaching.In the other cases the xref no longer appears, but some layers stay behind.

Stiene, I think that Marc, in his second post here, said that he's seeing exactly the same thing I am, which I took to mean the xref itself stays on the list in Explorer.But he said that he sees it in all files, not just certain files as in my case.

Just tried it and found that re-attaching and then detaching works for me, too. And it's much easier than the workaround I was using before. Thanks, Greg!

While you're working on the xref part, I would love to have a way to easily toggle xref states (overlay vs attach) like in Autocad. Sometimes people simply insert xrefs in the wrong state, and currently the only way to fix is to detach and reattach the drawing (loosing any finely tuned layer configurations of course).

Hello Stiene!

Is the problem with the detached xref-layers in the explorer solved in the meantime?

My version is 9.3.13 Build 16003.

I'm asking because layers of unattached Xref's are still shown in my explorer and can't remove them in no way. 

Thanks.

Thanks for answering.

The Audit command was good. After auditing the layers could be deleted.

Bye.
