Hi, we got errors converting autocad 2018 dwg’s to any format (see below)
on ubuntu linux, qcad trial 3.19.2
(we wanted to buy, but have to be sure the software can convert our files using command line tools..)

There are two different sets of packages for Linux:

  • the Qt 5 based packages for all modern Linux distributions (qcad-3.19.2-trial-linux-x86_32.run / qcad-3.19.2-trial-linux-x86_64.run)
  • the Qt 4 based legacy packages for older Linux distributions (qcad-3.19.2-trial-linux-qt4-x86_32.run, qcad-3.19.2-trial-linux-qt4-x86_64.run)

The Qt 5 based packages are recommended for most modern Linux distributions and support DXF/DWG <= 2018 (DXF/DWG R32).

The Qt 4 based packages are recommended only for older Linux distributions if the Qt 5 based version does not work due to incompatible gcc libraries. These packages only support DXF/DWG <= 2013 (DXF/DWG R27).
