AC$ files slowing down opening drawings

[ChrisHawkes]

Hello i'm new to the forum and could do with some help.......!

I have a furniture master drawing which xref's in the core for the building. The file opens quickly from the server, and i can see the graphics on the autocad screen, but the load seems to halt when it trys to load an ac$ file from my local C: drive. It takes a good 30-40 seconds to finish this final stage.

can any one suggest any resolves for this?!

okay, ya got me on this one.... what are you doing trying to load or open an AC$ file ?

AutoCAD operates using DWG or DXF files. An AC$ file is a temporary file

[ChrisHawkes]

thats the problem, i'm opening the dwg as usual but once it has loaded that, the system tries to find this ac$ file before the drawing is full open and editable. the file does exist but i dont see why autocad needs it to open the drawing.

Delete the AC$ file in your local directory.

Should have no problems after that.

hi there, i closed my drawings and deleted all ac$ files on my system, then reopened CAD to open a drawing and its still doing the same thing. i have all the 'create backup' etc option deticked in the autocad options.

its as if its having to create the ac$ file onto a local drive before it will full open the drawing.....very weird and annoying!

it has to do that ~ the AC$ file is the temporary file that autocad uses while you are working

what happens when you open a locally stored file ~ do you still get the same delay ?
how do you know it's trying to load the AC$ file from your local drive ? what messages do you get when a file is opening ?

it has to do that ~ the AC$ file is the temporary file that autocad uses while you are working
to explain a bit further... what actually happens when you open an autocad drawing is...

you "open" the drawing ~ Autocad copies the file (which now becomes the AC$ file) and places a lock on the original file to prevent it being accessed.
you work on the file... all your work is being recorded in the AC$ file.
when you "save" the file, autocad removes the lock on the original drawing, overwrites it with the contents of the AC$ file, then relocks the original

actually, there is a bit more to it than that but you get the idea.

ok, having bound the xref's to see if that was the problem, i'm still getting the same delay. I thought it was getting stuck on the ac$ section of the open. However if i watch the grey section under the comand line, it quickly fills up the blue progress bar up to 93% for opening the dwg then gets stuck for ages. the drawings are not very large or memory intensive at all.

[hendie]

I just remembered, I had a similar problem with 2006. When I would start up or open a drawing, the progress bar shot up to 100% immediately then hung there for about a minute or more every time.

I never found the cause of the problem but when I did a reinstall (for other reasons) the problem disappeared ~ so I put it down to a bad install... for whatever reason.

sorry I can't help more

[ChrisHawkes]

sounds very similar to what i've got although were still on 2004. will probably try the re install on one user then if that works do it on all machines
