I´m trying to export to .dxf for lasercutting but the scale is off. I´ve set view to parallel projection but when I go into exporting options the 1:1 option is not available and I can´t scale it manually. If I set both drawing and model to 1,0mm the width and height go bananas. If I try to enter A2 measurements into the width and height they go bananas.
The screen shot indicates you aren’t exactly on a standard view. In Parallel Projection with the standard top view, you wouldn’t be able to see the blue axis.
I found it by opening the group for editing and then dragging a right to left selection box through the bounding box without hitting any of the geometry I knew you wanted to keep.
