Qcad pro 3.9.4 crashed and destroyed my file

[jvalencia]

I was dividing a circle in N parts, when qcad crashed. When asked if I wanted to recover the backup, I agreed, but the backup was already messed.

How can I run qcad in debug mode to catch these errors?

Here I attach the resulting dxf.

Please find attached your fixed file.
There were three very large circles in your drawing that caused auto zoom to go out of range.

You can fix such problems easily using the selection filter:

Thank you!

I didn't draw those big circles. Not sure where did they come from.
