How to embed the partlibrary of QCAD 2.x to the new QCAD 3

The final release of QCAD 3 is out and the new features of this CAD application like the property editor, the new scripting engine, the new library browser, .dwg support and more are available to its users.
One very interesting feature is the new library browser that can handle  different type of files like .dwg, .dxf, .svg and scripting items.
Many users may want to use the old QCAD's partlibrary with this new release. The solution is really very simple and with a few mouse clicks you can successfully embed the old partlibrary into the new QCAD3.
So the only thing you have to do is to open the application's preferences and navigate to Widgets-->Library browser. Then you have to add the path  to the partlibrary's folder and/or any other location that includes files you want to use into the Library Browser.

Save the changes and restart QCAD3 and you're ready!!!

Lost in support:FreeCAD

FreeCAD is a perfect example of a well-supported application under Linux. Also its active community provides excellent documentation and support with lots of tutorials, answers and helpful advices all accessible with a few clicks from the application's homepage.

Dassault released an updated version for DraftSight

A new version V1R2.1 for DraftSight is available for download. Nothing special at all but the 2 very annoying bugs of the previous version ( No menus and toolbars when you install DraftSight on a system with different language than the supported and the segfault when there is no Internet connection available) have been fixed. So these are enough to update your current DraftSight installation.
Download the latest packages from here (32bit only both .deb and .rpm)

A TeighaViewer Update is available

TeighaViewer has just updated today in version 3.6.0. It has various new features like toolbars and some basic design functionality (you can now draw lines, boxes and spheres with it) but continues to have printing problems. You can read the full announcement, the changelog and download TeighaViewer for Linux from here.
Both deb and rpm files are available.

Lost in Support:Intro

The latest DraftSight V1R2 release was a disaster. Despite the localization bug this version also has some very annoying problems such as the crash when there is no Internet connection available. These problems gave me the idea for a series of articles that will evaluate, compare and rate the support level of the available Linux CAD applications.

Things to compare:
Installation/Installation Instructions
Active Bugs/Bug Fixes
Linux-related answers
Help/Command Reference
Development/Improvements/New features

Applications:
FreeCAD
LibreCAD
ARES CE
Bricscad
DraftSight
QCAD Pro
VariCAD

So how easy is for a Linux newbie and non experienced user to deal with these applications with only help the resources that the CAD vendors/developers provide?

How to install Bricscad V11 on Ubuntu 12.04 LTS

Bricscad V11 has a syntax problem in the description field of the .deb file. This problem causes a failure during the upgrade to Ubuntu 12.04 but it also makes the installer unusable in clean installations of Ubuntu 12.04. The fix is quite simple and similar to the DraftSight on Ubuntu 12.04 64bit workaround.
You have to edit the control file inside the .deb installer. Here is the complete workaround:

DraftSight V1R2 is out but it's broken

A new version of DraftSight has been released but it's completely unusable with the new Ubuntu 12.04 LTS. The application seems broken and I get a segmentation fault when I try to launch it. Sometimes the application opens but pull down menus and toolbars are missing. I'll try to investigate if there is any way to fix that but I don't expect any solution about this.
Ubuntu 12.04 users have to be careful with this. Don't upgrade if you don't have a copy of the previous DraftSight V1R1.4 installer.

DraftSight V1R2 on Ubuntu 12.04. Disaster!!!

Update: DraftSight V1R2 doesn't have any GUI problems with CentOS 6.2 32bit, OpenSUSE 12.1 64bit and Ubuntu 12.04 64bit ???!!!(All these are VirtualBox installations). On my Ubuntu 12.04 32bit installation I finally got back the toolbars but the pull-down menus are still missing.

Update 2: Finally I got a working DraftSight V1R2 on Ubuntu 12.04 LTS 32bit. The problem is that DS tries to load missing or invalid CUI and Menu files when your system locale is not English.
To get a correct looking DraftSight you have to:
- type options on the command  line and navigate to File Locations--->Interface--->Customization File and then load the correct application.xml file. Save the changes

This will make the toolbars visible again.

After that:

-right click on a toolbar and select Customize Interface
Navigate to UI Profiles--->UI Profiles--->Menu Bar, then click to the button show menu explorer and then drag 'n' drop all the items into the Classic default entry. Save the changes again.

Finally DraftSight looks OK again
