HOW TO FIX ACDB TABLE LINETYPE REFERENCES?

[Anonymous]

This issue has been driving us mad. This seems to be at the heart of the problem, our custom linetypes not being added to the database although we have them defined in the acad.lin that (findfile "acad.lin") points to.

Is the recover messages, so....how can we fix this?

Thanks in advance for any insights..

can you post a sample dwg with the lin files?

[Anonymous]

I sure can.

[Anonymous]

.lin file is an invalid extension to attach so I copied the text out and put it in a .txt file which I'm uploading now. It is the same that is in our acad.lin file that is pathed to

[fenton.webb]

Thanks for that...

And some steps to repro?

[Anonymous]

In order to get the errors you may have to load the custom linetypes into the drawing via linetype, then move the drawing to another machine that does not have the linetypes loaded (a regular acad.lin file w/o custom linetypes) and have that machine open the dwg, set the current layer to one of inst-L2 through inst-L5 and draw a line, then delete the line.

Once that machine has deleted the line and saved the dwg, when opening on the original machine that has the linetypes loaded already, is usually when we were getting the errors.

I am not certain if this will reproduce without our linetype files, which I can provide you if another option that this forum' attachments is available (due to .shp and .shx not able to be attached, which is strange in of itself)

Thanks again for your time and your attentions, solving this issue or at least finding the cause in case it creeps up again for us would be very useful.

We have a similar problem with corrupted linetype references, and we would like to delete these linetype references, so is there a way to do this?  In the DXF files we see long lists of corrupted linetypes, and these cause some drawngs to be so slow that they become unworkable.

The references we'd like to remove look like this in the DXF file:

And suggestions?

Loading your lin file, it has corrupted line type definitions - do you see the same thing?

I believe this is more of a product issue rather than an API issue. Obviously, using the API you could remap the recovered linetypes back to the originals - but surely the solution here is to make sure that the linetype file exists on the new machine - doesn't etransmit help here? (sorry, I'm not a user of AutoCAD so I might be being dumb asking this :-))

[Anonymous]

Intreresting, the lin files come in without any messages for us, though surely that is the problem

[fenton.webb]

Does the -purge command not help?

[Anonymous]

It does not

I have purged and done everything I can think of to get rid of these
corrupted linetypes. I'm attaching a drawing with just a few polylines in
it. Can anyone rid me of this troublesome linetype?

[fenton.webb]

can't see the DWG file?

[nedwards9820]

I replied direct from email with the drawing attached.  I guess the text makes it to the forum but not the attachment.  I'm attaching the drawing from the forum now.

thanks

 For some reason I can't attach it as a .dwgso I've renamed the file with a .txt extension

[fenton.webb]

thanks for sending the dwg file.

I loaded it into AutoCAD 2014 then examined the DWG structure using the MgdDbg app, and I failed to find anything wrong? Here's a sreen shot of the Mgddbg app examining the database, as you can see - it seems ok. I also tried a recover on the DWG file, it reports an issue with a dimstyle but that's it.

[nedwards9820]

PLease try writing the file out to dxf format and you will find the
linestyles listed. They appear benign in small files, but when the files
get large and used as xres, the embedded Microstation .dgn lientypes make
the drawing almost unusably slow.

I can post examples of bigger files, but I'm pretty sure the problem lies
in these corrupted linetypes -- so I'd like to be able to delete them --
especially as they are not used,

Thanks, I didn't know this was related to DGN - you probably have already seen this post, did it help? http://through-the-interface.typepad.com/through_the_interface/2013/07/minor-update-to-the-dgn-purge...

Thanks -- i didn't know about the DGNPURGE command.  I'm running AutoCAD14 and I didn't need the hotpatch.

DGNPURGE seems to work.

We still have a major problem with our drawings even after multiple DGNPURGE's.  But if we select all the text in the drawing and just delete the lot, the problem (extreme slowness when drawing over an xref) is fixed.  Brutal, but effective.
