LibreCAD is an important piece of software for the OpenSource community. Currently it is the only available and mature OpenSource solution for 2D CAD.
Let's see what happens with its Linux Support.
Importing PDF files is a missing feature from all Linux CAD packages. However there are some very interesting and simple workarounds to bypass this problem.
Linux is famous about its fancy Window managers. Compiz, Kwin and e17 are some of them with different capabilities each one. But these fancy things are only for fun??
".dwg" is a well-known, proprietary CAD file-format. Originally developed by Autodesk and commonly used, it's a headache for other CAD vendors and a big obstacle for the creation of a good Free and Open Source CAD application. CAD vendors have a very good solution called ODA, but the libraries which are provided by ODA are proprietary software so they cannot be used on a Free and Open Source project like LibreCAD.
After testing Ubuntu 11.04 with the new Unity Shell for some time, I realized that the old way to embed QCAD's partlibrary in LibreCAD via the creation of the .librecad folder inside your home folder doesn't work anymore.
I have found a better way to use partlibrary with LibreCAD which I expect that works in all distros and OSes.
LibreCAD is a 2D Open Source CAD that today made the big step. Just a few minutes ago released a version that runs on the Cloud, so it became the first CAD ever that has an official Cloud version.
As I wrote in Part I LibreCAD is primarily focused on occasional and amateur CAD users.
That doesn't mean that you cannot use it for professional purposes.
