XREF Mysteriously Growing in Size

[ReMark]

I've never had a drawing file size increase using the Purge command. Did I read you (pefi) correctly?

 

When I ran the Erase > All command AutoCAD reports back 50,797 objects with 2 not in current space.

 

I ran the purge command (command line version). Purged 21 Regapps on first run. Purged 1 Table style on second run.

 

I ran an Audit. AutoCAD reports back 231,800 objects audited including 139 blocks. No errors found.

 

Did a "saveas" to 2013 DWG file format and during the process AutoCAD told me there were 280 unreconciled layers displayed out of 592 total layers (312 used layers).

Yes, it's correct. But I just find out it _might_be because of updating format i.e. from 2004 to 2010. See attached example (75.8kb) and after purging and saving it grows to 88kb. Again I just found that it's 2004 file and I have "save to" default format set to 2010. I'll post more if I can find something else.

While attempting to WBLOCK the draw out AutoCAD noted there were numerous instances of duplicate definitions of blocks. Any idea how that happened? Here's a list:

 

Duplicate definition of block Well ignored.

Now that you said you purged then saved to a different file definition format it makes sense. The increase in file size is NOT due to the purging.

Paul: These are the file sizes I've seen so far.

 

Your original drawing was 9.5MB. Doing a saveas to 2013 file format resulted in a very slight decrease to 9.3MB. Using the WBLOCK command then saving to the 2013 file format I was able to get the size down to 7.1MB.

 

I opened the WBLOCKed version and ran OVERKILL on it. AutoCAD did not find any duplicate objects but it did find 186 overlapping objects. I also checked the number of layers which dropped from 592 to 154. Big difference.

 

Checking linetypes loaded I have 30 listed of which 7 look odd. They all start like this: FREZ_B1-F$0$... Do you have any idea how these originated?

 

There are 15 text styles listed one of which begins with the letters FREZ.

 

If I draw a line from 0,0,0 to the endpoint of the line in the topmost left hand corner of your drawing the coordinates come back as:

 

from point, X=0.00000000 Y=0.00000000 Z=0.00000000

to point, X=6319245.58844013 Y=2158772.04309526

 

I'm assuming this is not unusual in civil surveys based upon state plane coordinate systems. is that correct?

 

Freezing layers TP-GRD and TP-GRD-TREE reduces the number of objects from 50,788 to 40,907. At least it makes moving around in the drawing a little quicker.

 

Alright, I think I am done here. No more analysis. Not sure if any of the above will give you any insight into the problem or not. As others have said perhaps the best way to go is to use xrefs to the extent that makes sense. Otherwise, I'd look at a huge increase in the amount of RAM installed so you can better handle files of this size and larger.

Fyi

I have a question. Why do the commands Erase (All), Audit and Status report back different numbers of objects? For the drawing in question I got 50,788... 231,800... and 173,135 respectively. Just curious.

A BIG thanks to all of you for taking the time to take a look at this drawing!!!

 

One thing I did was to delete the unused annotative text scales. I did the OVERKILL/-PU/REGENAPPS/AUDIT/ blablabla again, and I even attached a couple references that are needed and made sure those were cleaned out to....and the drawing dropped back down to 7.7Mb and is running much faster.

 

Thanks again! Cheers!
