If the Y axis of your machine points south, you can adjust your machine configuration to flip entities along the horizontal (X) axis before exporting. I will post an example configuration in the other thread at:viewtopic.php?f=74&t=2625

Drawings in QCAD have generally a scale of 1:1 (real size). You can adjust your machine configuration to scale output if desired if that is what you had in mind. Otherwise, please elaborate.
