Dxf/dwg export scale info

Hi,

I’ve noticed that dxf/dwg exported files don’t appear to have scale information so when opening in a dxf/dwg reader the dimensions are all off (by the scale of the drawing in Shapr).

This can be corrected by the recipient by changing the scale of the imported drawing but my understanding is that dxf/dwg drawings are usually exported at 1:1 with relevant scale information included.

Not sure how this works for a drawing that includes parts at different scales.

Thanks
Simon
