How to read DWG files?

You could use irfanview in wine (maybe)

or natively:
http://lx-viewer.sourceforge.net/

I am interested into Ubuntu based solutions. lx-viewer requires hand compilation for opendwg library as well as lx-viewer itself.
I'll try to see whether irfanview with its plugin wil work in Wine. Any experience with it?

Thanks actionparsnip, that solved my question.

 ./iview427_setup.exe
err:module:import_dll Library MFC42.DLL (which is needed by L"Z:\\home\\auser\\Desktop\\Files\\iview427_setup.exe") not found
err:module:LdrInitializeThunk Main exe initialization for L"Z:\\home\\auser\\Desktop\\Files\\iview427_setup.exe" failed, status c0000135

Not working without that DLL!

The vry same problem is also here (unanswered):

find the dll online and put it in the folder ~/.wine/drive_c/windows

you can use http://www.dll-files.com

They are free and clean

Done. Nothing happens.
From command line I just do:

 ./iview427_setup.exe

something seems to be loaded from the disk then nothing more.

My system is 64 bits, maybe this matters.

It won't as wine handles all that stuff.

If you have windows installed, you can copy the file over from the windows\system32 directory. If not, you have to download the .exe file from support.microsoft.com. It's quite a tedious process, as you have to run it to unbundle a slew of other files. It probably won't run under Wine anyways. So, the next step is to get the file from a friend who has windoze.

I tried Irfanview under Wine. I wasn't impressed with it at all. It runs better on Windows.

There's no way. You need Windows and its stupid tools.
