I am not sure where to put this, but I am having an issue and I am not sure what to do about it.
The issue is I made some draws a few months ago and saved them. I tried opening up a dwg file and it was blank... I installed a CAD viewer on my tablet to look at it and to see if I could save the file as a dxf. That worked, however the file when opened in Libre CAD was still blank. Yhen I opened up the files I saved months ago and they are blank as well. I DL them to the tablet and opened them in the viewer and they look fine. So what have I done wrong?
Yeah I zoomed in and when it asked me to save the drawing I did not save it. I have been able to look at the files in my viewer and they are all there. Libre CAD is just not seeing all the layers and everything in those layers. I even unistalled Libre CAS+D and reinstalled it. Still my drawings that I did in Libre CAD are empty.
Now that I remember, I have a bizarre problem when opening files with LibreCAD:
If I click on the menu file->open and select the file to open in the file dialog, then LibreCAD says the file opened, but it is empty.
If later I click on the menu file->recent files->same file, then LibreCAD opens it correctly.
It happens to me with current git and with old 2.1.3 in a Linux Debian Sid(unstable), so I don't think is LibreCAD itself the problem rather than the file dialog.
I don't think it is the cause of your problem, but I mention it just in case.
BTW, did you mention the LibreCAD version, operating system, etc?
I was about writing a bug report on this and found it is already there, with another workaround.
In the file dialog, you must ensure that the Files of type; field is showing Drawing Exchange (*dxf) instead of QCad 1.x file (xf)
