Why is it so and how can I fix it,

I recently started to use Onshape. Making plans for a letter box, Sent my DXF to the cutters, whose response was WHY is your letter box 32mt tall.
Checked my units settings (OKmm) checked my file with eDrawings to find the 32mt tower.

So what am I doing not right

THANKS anybody.......................

They need to set the units on their software when they import, as the DXF file format is unitless

Never had problem's about unit's when you export directly from a planar face, like this

See this discussion thread from a few weeks ago.  In summary, DXF file format is unitless, but there are some parameters that importing software use to "guess" at the units. Sometimes they get it wrong. 

Dimensions not correct when exported from OnShape — Onshape
