As I continue my evaluation, I have tried the Linux version. Some things seems broken.
One of my big issues was placing objects where I want them. The help here got me sorted out on the Windows version, but the same thing does not seem to work on the Linux version. In the Windows version I set a flag that automatically sets the UCS to WCS, that plus using #x,y,z always works. In Linux, the flag to set UCS to WCS by default is grayed out, can't set it. Manually setting UCS to WCS does not work either. Whenever I try to move an object to an absolute position, it just doesn't move.
UI issues - This is common to many Linux programs I run, the UIs are poor in that text is the wrong size, it not position correctly..... I have used Linux for as long as I can remember. Most the issues I see come from, is it KDE, is it Gnome, and now add is it X11 or Wayland? What environment was Bricscad built on?
