ODA Drawings Explorer (formerly Teigha Viewer) is a free (not libre) viewer for proprietary DWG files, developed by Open Design Alliance.

The developing company provides RPM and DEB packages for easy installation at their site.

I download the 64 bit DEB package, and install it using:

sudo dpkg -i TeighaViewer_QT5_lnxX64_4.7dll.deb

After that, the software is easily installed and I can run the software from Dash (windows key + typing Teigha) or from bash with the command

TeighaViewer

The software loads quickly and automatically prompts to open a file. This is where the trouble beings... and ends: the moment I select any DWG, TeighaViewer consistently crashes every time.

  • Regardless if I select big or small DWGs
  • Regardless of the location of the files I select or permissions.
  • Regardless if the DWG file was generated with a new or old version of AutoCAD
  • Regardless if I install the Windows version of Teigha with wine and run it

In all of these cases, Teigha systematically crashes.

I have even tried to open the DWG file directly from command line by issuing:

TeighaViewer myTestFile.dwg

But it still crashes. Note there are no spaces in the name of test DWG file being opened.

When running Teigha from command line, there is a hint of the problem though:

~$ TeighaViewer myTestFile.dwg 
QString::arg: Argument missing: Property Dialog, Teigha Viewer
QString::arg: Argument missing: Property Dialog, Teigha Viewer
terminate called after throwing an instance of 'OdError'
Aborted (core dumped)

I have googled everywhere for these errors, and came empty handed.

Could the be related to missing QT libraries?

My setup:

$ lsb_release -a
Description:    Ubuntu 17.10

$ gnome-shell --version
GNOME Shell 3.26.2

$ uname -a
Linux 4.13.0-36-generic #40-Ubuntu SMP Fri Feb 16 20:07:48 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

$ cat /proc/cpuinfo | grep model
model       : 142
model name  : Intel(R) Core(TM) i7-8550U CPU @ 1.80GHz

If anyone was able to make TeighaViewer run on Ubuntu, I would like to know their setup (Ubuntu version, 32 or 64 bit, graphics card in use)

  • Make sure all dependencies were installed. Run sudo apt -f install – estibordo Mar 22 '18 at 10:55
  • Use this simple draw https://github.com/qgis/QGIS/raw/master/tests/testdata/dwg/entities.dwg – estibordo Mar 22 '18 at 10:56
  • There certainly seems to be something wrong with the installer on that application because when I tried, it couldn't even find its own shared objects. As a possible alternative, there is a DWG application available from 3DS for Ubuntu (although its still in beta) and it is available here. I've tried it in the past and it seemed to work well. – gsxruk Mar 22 '18 at 19:34
  • @estibordo Nothing else is installed with that command. System is 100% up to date. The test DWG file also crashes Teigha upon loading. Does this indicate anything in particular? – chronos00 Apr 16 '18 at 13:09

It's also available on Flathub (related answer).

flatpak install flathub org.freecadweb.FreeCAD

Note: the qt5-default package is not available for Ubuntu 21.04, you have to use some workaround. To get Qt 5.14 on Ubuntu 18.04 LTS and 20.04 LTS you can use this answer.
