I have been using AutoCad 2k for the last 20 years. I used it in dual boot mode, with Mandrake and Win2k at first.
It would run fine under WINE, but still had issues when plotting, so I had to reboot to Win2k to use it with my printer.
After switching to Xubuntu, I also started using it in a WinXP virtual machine. No more reboots, and no more plotting errors under WINE.
The time has come to take another big step, and become totally MS free!
I installed LibreCad this past week, and have been doing the tutorials to get used to it.
It is different. It will take some time to get used to the software.
