Can't open DWG

Hi.

 

I received a drawing from one of our consultants and somehow can't open any version of it they've sent.

Already tried recovery and referencing.

I don't which version of Civil 3D they use but my is 2013.

However I can open it in DWG Viewer and Global Mapper.

 

Any ideas?

 

Thanks

You could try to open it in Autodesk Trueview, then convert to an older DWG release...

Are you getting any specific error about it not opening? Have you tried a Partial Open? Can you open it in Design Review?

I was only lucky, gentlemen...

I'm still wondering why Vasily's C3D 2013 cannot open the original drawing: perhaps has it been created by a 2014 release?

I thought 2014 drawings could be opened by 2013. At least, that was the intention.

According to Autodesk a 2014 drawings should open in 2013 and have the Civil 3D objects usable. In any case it should have opened in 2013 with proxy objects if nothing else. Maybe it was exported from another piece of software and was supposed to be compatible but wasn't quite. You'd have to pick apart the drawing file to find out. The only thing I know how to tell from a drawing file is what version it was produced in.

 

Just good that TrueView was able to rescue it. I wonder if any Civil 3D objects survived. I wouldn't think so.

@ Vasily

 

Could you paste here the first 6 characters of the original .DWG opened in Notepad..?

I doubt that it was 2014 version.

That would be an AutoCAD 2007 release drawing file. So if it's the original file, it would be from an old version of the program. It also might have been a Save Back. Some trouble might have been created if the drawing was only saved back to the earlier version instead of using Exporttoautocad.

 

That's all speculation anyway.

AC1021 might be release 2007 up to 2009, according to this paper.

Sounds like that 2012 (i.e. AC1024) can't read 2013 files, while 2013 will be able to open even 2015 ones (AC1027).

We are having problems opening some of our drawings as well.

Recently, our IT department upgraded our existing XP computers (32 bit) to new W7 machines (64 bit). We reinstalled AutoCAD C3D 2012, with ARD and Stringer including all Service Packs

This upgrade seems to have gone well with a few exceptions.

One or two of our drawing cannot be opened on the new  64 bit W7 computers.

They are typical drawing with nothing out of the ordinary in them

Opening these particular drawings runs as usual till it gets to 93% complete

An AutoCAD Application box appears with....

AutoCAD Application has stopped working

Windows is checking for a solution to the problem...

Then

AutoCAD Application has stopped working

A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available.

 

Then AutoCAD shuts down.

I can then load the same drawing onto the XP machine without problem. I have purged out the drawing, resaved it but still it closes in W7 computer.

Any suggestions

Try running a 'recover' on the XP machine. If it fixes anything, try it then on Win7.

Another place you can get a clue is in the bottom left corner of the screen. Typically it will say
"Opening.....
Resolving xref....
Synchronizing references....

Keep an eye on that during the open, it might let you know what step is causing the crash.

Hi,
Thanks for the information.
I recovered the drawing on the old computer as requested but it still does not open.
There are no errors in the command lines as the drawing loads up.
As stated before, it gets to 93% and then closes
