That’s pretty funny from someone whose company pushes DXF, a really old format that generally does not support bezier curves (technically the standard can, it’s just that virtually everyone implements the lowest common denominator version of the spec). It’s also not uncommon for them to come through unit-less as well - the receiving app needs to scale it (which is why 1:25.4 is a magic scaling number to try when importing a DXF).
