.dxf files : quel format / what format ?

Hi,

Example file : Y-Carriage

I tried viewing the dxf files from the github with LibreCAD, but come up with an empty workspace each time. What format are the files ? What open source software will read them ? Thanks in advance.

J'ai essayé de lire les fichiers .dxf du github avec LibreCAD mais l'espace de travail reste vide. Quel est le format de ces fichiers ? Avec quel logiciel open source je peux les visionner ? Merci d'avance.

First time that has happened to me! My .zip file was corrupt, but the extract didn't report any errors. I've downloaded again and now all is OK.
