Does this support 3D

[Mr-Skribbls]

Hi we're trying to utilize your package to convert DXF to DWG. We're having some troubles with converting. When we try to convert 3D DXF to DWG we're having some problems. Does this package support converting 3D DXF to DWG?

Hi @Mr-Skribbls,

Yes it supports 3D, I've detected some problems with the materials in the newer version because they are not saved, the implementation to solve this issue is ongoing.

Could you provide more details of what are you trying to accomplish? Can you provide an example file so I can test it on my end?

[Mr-Skribbls]

I'm using version 1.1.6
I've attached some example DXF files we're trying to convert to DWG.

When trying to convert I get the following errors:

The attached DWG files are what was produced but they don't work when trying to plot with AutoCAD.

Thank you for your help.

Hi @Mr-Skribbls,

These are not exactly errors, only notifications of dxf codes that couldn't be assigned, most of them I'm sure that aren't documented and they have to be checked manually.

I've tested your files, if I save the dxf in a dwg using a software like Autocad, the re-save works fine, the issue seems to be that some entities read from the dxf may be badly formed or build, which result in a corrupted file, I'll open an issue to take a look at this issue.
