New to using Draftsight Software.

My Draftsight 2020 Professional DXF file text format changes when my customer uploads it into Catia R2019X.

Their font seems to be larger and there is no wrapping of text.  

Example if I have Font size 8 they may show a Font size 12 and this causes the text to go outside the boundaries of our 2D DWG.

I get a ".DWG" from my team that creates it originally in AutoCAD.

There is a reoccuring error with a "hztxt.shx" not being found, so I choose "BigFont.shx".

Does anyone know a reason why this may be happening and how to fix it?

Any help would be greatly appreciated and thank you in advance for any help one can provide.
