I am an AutoCad veteran using it since 1999 as an Engineering student and later in civil engineering and construction jobs. It's been a year now using Linux and to resolve the need of using AutoCad I had a Windows partion on my notebook.
I have recently discovered Bricscad, which for my simple 2d needs is faster and less bloated than AutoCad. The trial deb files downloaded from Bricscad installed and worked perfect on my desktop using Linux Mint 64bit. However, Mint Debian on my new notebook took a little time to work out.
Once the deb file is installed on LMD (64bit) the program may not open. If so go to the terminal and type Bricscad to launch it, you now will shown the error as in my case: ERROR WHILE LOADING SHARED LIBRARIES: LIBGTK-X11-2.0.SO.0: CANNOT OPEN SHARED OBJECT FILE: NO SUCH FILE OR DIRECTORY.
Solution: open package manager and install: ia32-libs-gtk and ia32-libs.
I am now 100% Windows free, with some smooth operating, low resource using packages!
