No. Read the "README.md" to the last paragraph. Even if I do you will not be able to make sense of the data it contains.

Hi Daniel, It got me thinking about if or how BricsCAD does it.

I don't think you know Mick Dupree, but he is another one of those people out there there sees the lack of innovation and the damage from proprietary formats. I will ask him about it later. I have seen his code at work for many years. He says he is putting together MetaCAD.

Getting around the encryption can be done with some creativity, besides conversion to mesh, but it would take a lot of time and netDXF is excellent as it is.

Always typos and bugs in my comments. :(

Perhaps BricsCAD uses the Autodesk RealDWG SDK. It is a library to read and write DXF and DWG files published by Autodesk but it is behind an outrageous pay wall, something that all companies should release for free. My main issue is that the sole owner of the file generated by a program holding your data its you, and companies must provide a way to be able to read your data without the use of their software. Ideally it will and SDK freely available, but at least a complete documentation of the file format. It is not like nobody does it Autodesk should learn from what Adobe has done with the PSD and PDF format or Microsoft with the DOC and DOCX; and it is not like it has hindered their business.

No, I do not know Mick Dupree and I agree. Abusive copyrights, patents, research papers behind hefty pay walls (knock knock Elsevier) this is what hinders innovation. That is why AutoCAD is no more than a glorified 2D drawing program.

And this is getting out of topic.
