Left hand dwg files won't open

[schiltz3]

The left-hand dwg files for the normal acrylic case won't open using AutoCAD or dwg true view. I also can't convert them to svg's.

Which files specifically? I just pulled them down and was able to open them in FreeCAD.

Maybe related: The scale of the left hand dxf file is all wrong. It shows the board as about 4m wide.

Specifically, this file: ErgoDOX Case Layer 3 Plate - Left.dxf

I was unable to open several of the left hand files, too when I tried to import into inkscape. The file opened fine on Autodesk viewer. When I found this issue here and tried the right plate file, it opened without error in inkscape. I compared the two and found that the right file used periods where the left file used commas. I replaced them in the left file and that seems to have solved the problem:
155,43284551931851 now looks like 155.43284551931851
The drawing LOOKS okay now that I've got it open, but I'm not 100% certain I didn't overwrite an important comma

The right files appear to have a lot more in the Header as well but I don't know enough about DXF to know what that's doing.
