12 meg drawing 4 minutes to open?

i mostly work on smaller size drawings but have been sent one thats about 12 meg file size, when opening it it gets to about 45% and then stalls for about a minute or two, if i use the drawing as an xref it takes about 4 minutes to attach it as an overlay. looking on google for ideas i have checked the scale list and that is ok, i have read about associative hatch slowing down drawings but is there a way to diss-associate hatches in the whole drawing easily? anything else i could try? i have removed unwanted layers and purged also. i am using cad 2010 btw.

12MB? Yeez....what's in that thing, the whole of UK? Have you tried -purge > REGAPPS ? (note the hyphen first)(answer No when it asks to confirm each item purged, it can be a whoole lot!)

Is it unintentionally 3D? Z-heights on lines that don't need them?

I have had this problem too only my file took 45mins to load

I colleague told me that there could be a few reasons for the problem.

1. Hatching (solid to be particular)

2. Large Photos i.e. ariels

I subject if you are going to use this as an xref that you remove as muck solid hatching as possible or replace it with another type of hatch and make it look as if it is solid when it prints and if there are ariels try to compress them as much as possible

Hope this helps but there are a properly a million reason why it takes so long to load can you give us an example of the type of enteritis in the dwg

We did some GIS data migration a few years ago and used MAP 2004 on files that were between 120 and 150 MB. That was a bit on the slow side but it coped OK after it had loaded.

Oh my gosh dude.... If i get 10MB files I usually crop the bleep out of them!

Is the drawing being accessed via a network?

What are your system (hardware) specs?

File size in itself means nothing, I have open now and working in a 8592KB file (8.39MB) it opens in 8-12 seconds. It is just line work and some hatches, just a lot of it. Other files I have that are smaller but with Images, take a long time to open. The big problem with hatches, I believe, is when they are far from the origin, I haven't noticed associative or non-associative being a problem. I also believe blocks far from their origin slow AutoCAD down also.

Wouldn't hurt to -Purge, Audit and flatten if not a 3D drawing.

I once was blind now I can see. Thank you SLW210.

No other drawings giving you problems of the same type at this time? If "no" then I would assume a problem inherent to the drawing itself and follow the suggestions as submitted above. If "yes" then it could be a matter of just too much going on for your system to handle. One option would be to disable many of the Win7 features that hog system resources without providing much in the way of substantive benefit. I could provide you with a list of these "bells and whistles" should you be interested.

Let's hope the problem is specific to just this one 12MB drawing.

I could use that list if you don't mind PMing it or maybe a write up in Software section. Windows 7 seems OK so far, but I just do not need all the bells, the whistles are OK. We have a few engineers here complaining about Windows 7 and trying to get IT to put them back to XP, figure maybe I could tone 7 down for them.

As per your request. The source was a recent issue of PCWorld. I condensed the article to its main points for the sake of brevity therefore one does not see the "how to do it" explanation. I'll see if I can locate a link to the full online article and include it as well.

the drawing is on my pc so no network, and it is just this one drawing so its no big deal once this jobs finished, trouble is they keep changing the shopfit drawing which means swapping the xref. i'll have another go at slimming it down later just out of curiosity.

Thank you Paul for the update. Glad to hear it is an isolated problem.

Another suggeston we tracked it down to be a line type that was made up of dots the scaling was all wrong and it would attempt to draw every dot, check your dot hatches also.

well in the end i had to wblock the dwg as the file size ballooned to 28meg, after wblocking the drawing i deleted the original and purged but the file size was still 28meg, anyway the new drawing file size is a mere 2.5meg. took me an extra hour to do all the drawings but i did not want to put a 28meg file on buzzsaw, it would not have looked very professional.
