X-ref Clipping Problem

Recommended Posts

I have recently encountered issues when clipping x-ref files in Architectural Desktop 2004. When drafting my building sections I generally reference the base plan as an overlay into my section base file. At this point I clip the referenced plan to the location that I am going to cut the building section. I have never had a problem with this process in the past. However, today I encountered a problem where certain portions of the referenced plan disappear for no apparent reason. The clipping command works correctly however random lines on the remaining portion of the plan will be missing. If I create a new clip boundary, in a new location, a different series of lines will be missing that seem to have no direct relation to the ones missing from the previous clip. When I delete the clipping boundary the plan returns to its original inserted state.

 

I have clipped and unclipped the same file several times in order to draw several sections on the same section base file. Could this be the root of my problem? If so is it possible to somehow purge old clip boundaries that may be interfering? I have attempted detaching and reattaching the file numerous times with no success. I have exhausted all possible solutions that I can think of. If anyone has encountered this probem and might have a suggestion on how to resolve it I would greatly appreciate it.

have you tried just starting a new dwg and see if the xref behaves the same.

 

i have had this problem also tho only once, and reconstruction of the dwg fixed it

 

also, is the xref coming from the same version, mostly likely i presume it is.

The x-ref was created using the same version of software. I will try starting a new dwg to see if the problem persists. I have tried WBLOCKing the sections into a new dwg and then inserting the x-ref and the problem persisted. However, I have not tried a new dwg without the sections I have drawn from the old dwg included. I will try this technique to see if the problem is resolved. Thank you for the comment.

was wondering if you attach the dwg here of the one you are having problems with... just to see if the problem exists also from my WS...

or whoever wants to tinker with it.

 

it is possible that something is not working right with the AutoCAD you are using of which is not that unusual.... i have had to reload the program myself at times just to clear up problems...

Obviously I would audit the drawing and xref first to make sure there is no corruption. Beyond that, try changing the indexctl variable (it can be 0, 1, or 2 I believe). This variable is what determines how acad organizes the data on the screen, and xrefs in particular.

Raymond, I would post the file for you to experiment with if it were possible. However, the building I am working on happens to be a correctional facility and I don't suppose my supervisor would allow me to do so. However, I will audit the drawing to see if there is any corruption as well as try tinkering with the indexctl varialble. I will let you know how it goes!

I was able to fix my x-ref clipping problem by starting a new dwg and inserting the x-ref. It is a bit inconvenient because I have to paste the section I want to work on into the new dwg file for editting and then past it back into my base section file with the rest of my sections when I am done. I am still clueless as to why the other file mysteriously started acting strange but it is comforting to know that it does not happen in a new file. The only conclusion I have been able to make is that the problem has occurred because I have clipped the x-ref file numerous times within the same drawing file and it has somehow uncovered a glitch in ADT. I appreciate your comments and if you have any further thoughts on the error I would love to hear them.

 

On a side note, I did run an audit on the base file and it found 2 errors. I did not fix them in fear of screwing up something. What exactly does an audit do and what exactly is an "error"? Do you think this could be the root of my problem? Thanks ahead of time for any thoughts you might have.

this is a very rare problem to have...

so reconstruction is sometimes the only way to fix this...

i wouldn't worry about accepting the prompts from the Audit.

these come about from something that isn't working anyway and will not damage anything thing that is... also with xrefs it ussually better to use the overlay option if they aren't nested. well at least you didn't loose everything... and were able to recover.
