I'm new to LibreCAD and CAD drawing in general. I have watched several tutorials and feel I can modify simple .dxf drawings (quadcopter frame design in my case).
The original drawing I work on did not have all lines going in the same direction, plus the modifications made by me (using mirroring), so I decided to fix it. Using CTRL+R I painstakingly reverted the directions of all lines on the drawing which needed it. I saved the file. After re-opening the directions were just like before. I fixed the directions again and 'saved as' a new file. After re-opening the directions were messed up again. Looks to me like LibreCAD is not saving the 'revert direction' modifications or perhaps, being a newbie I am doing something wrong or do not understand this function properly....

Thanks for this suggestion, but I do not think I can redraw this using just two point lines (if I understand you correctly). On my drawings all corners are curved in order to avoid creating stress points which would initiate fractures in crashes. I draw the curves using mostly 'center, point, angles' or '3 points' or 'arc, tangential'.
I have noticed that none kind of lines I use, whether it be 2 points straight lines or the three kinds of curves mentioned above, none of them saves properly. After re-opening the saved file they are all messed up, like before saving. Other modifications (new entities, change to shape etc) save without such trouble...
I guess I will need to use some other CAD program (sounds like an abomination, I know ) just for the task of reverting the directions of the lines on my drawings...
