How do I install Draftsight CAD?

I've installed the 11.04 64bit version and now i can't install Draftsight (32bit with force architecture option) because there is an error with the library libexpat1.. anyone know how solve?

andrea@andrea-HP-Pavilion-dv5-Notebook-PC:~$ sudo dpkg --force-architecture -i DraftSight.deb 
[sudo] password for andrea: 
dpkg: warning: the following problems are ignored via the --force option:

After you install all dependencies mentioned above (that is libdirectfb-extra, libxcb-render-util0, libaudio2) you should install Draftsight using the following command:

sudo dpkg -i --force-architecture,depends ./DraftSight.deb

Obviously you should run this command while inside the folder where you have saved Draftsight.deb.

Free AutoCAD clone ‘DraftSight’ hits Linux Beta

Download a pre-packaged .deb file for Ubuntu 9.10+ at the following link: download (66.8MB)

64bit Ubuntu users note: The DraftSight beta .deb provided is 32bit. To get DraftSight to run in Ubuntu 64bit will need to install the following missing library:

 sudo apt-get install libdirectfb-extra libxcb-render-util0

After this, install the .deb via a Terminal using the ‘force architecture’ command. Assuming you downloaded it to your Downloads folder:

sudo dpkg --force-architecture -i ~/Downloads/draftSight.deb

You probably did not install the missing library.

On 64bit Kubuntu 12.04 there is a libgtk-x11 error.

Solve with this:

sudo apt-get install libgtk2.0-0:i386
