What missing packages do I need to install to properly run DraftSight?

To easily install and run DraftSight CAD in 64 bit Ubuntu you need to install several i386 packages:

sudo apt-get install libuuid1:i386 libice6:i386 libsm6:i386 libxt6:i386 libaudio2:i386 libgtk2.0-0:i386 libcanberra-gtk-module:i386 libcanberra-gtk0:i386 libglu1-mesa:i386

Then just open the dash to start the application:

This is tested on my pc (Ubuntu 14.04 64 bits):
Install package libgtk2.0-0:i386 then Draftsight will install ok.
