fillet trimm

OS: Linux Mint 18.1     Libre CAD 2.0.9-2
With this version the fillet (old: rounding) command does not work properly. It makes a new line which you can then delete instead of trimming it like it should. How ever I work for my cnc machine this is a big error possibility.
At version 2.0.2+nolibs-1 this command is running perfect.
Any idea? your help will be highly appreciated

Try to get a newer version. In 2.1.3 you have this, appearing only when the fillet command is active:



Regarding the overlapping lines problem, I don't know a solution. I think this would need a special feature to be developed.

Thank you so much for your prompt answer dellus
If I untic this box Librecad will delete the whole line. It is very wired . In my older version there are no overlapping lines. It just trims the edges.
I recon 1 thread with the same problem but I could not get around.
The command  "$ sudo add-apt-repository ppa:librecad-dev/librecad-stable"
does not change anything.
Can you help me please to get a newer version?  command line orders to copy and paste are highly appreciated.

Sorry, I can't help you with that, I am not a Linux guru. I play with Puppy Linux a lot, but unfortunately I also don't succeed to install the latest LibreCAD version. Maybe someone else can help you.
