Moi3d dfx export issues

Good day.
I am setting up sheetcam software right now...
However when drawing in metric size a rectangle of 121.4cm x 243,8cm and when I try to export a dfx file from Moi 3d it comes up too small when I import in sheetcam.
Sheetcam has an option to import metric, inches and custom.

And the only way I can make it to match a sheetcam material of 48x96" is to use the custom option with a multiplier of 10.16.

Anything I can try in the export option to fix this?

Thank you!
