nanoCAD forum

I have a problem in importing old simple DXF files. I attach an example. These files are read by progeCAD 2007, Solid Edge 2D, FreeCad, QCad and LibreCad.
The message of NanoCad is "unknown error".
What is the solution?
Thank you very much!

Hello!

AutoCAD 2010 also cannot open this file -
Incorrect version number detected: "AC2.18".
Broken DXF-file.

We'll check why nanoCAD cannot read it.
