Blender 3.0 compatibility issue : can't export shapefile

[ChameleonScales]

Blender and OS versions

Blender 3.0 BlenderGIS Master 2.2.6 (also tested with release 2.2.5) Debian 11

Describe the bug

Using the simplest and most compatible shapefile I could think of (created in QGIS 3.22.1), I could not re-export it from BlenderGIS no matter my export settings. This is likely due to an API change since 3.0 because it works on Blender 2.93.4. Attached below is the shapefile which contains one small polyline rectangle, projected in EPSG:4326 - WGS84 somewhere in France. shapefile-example.zip

How to Reproduce

1. GIS > Import > Shapefile
2. select shapefile-example.shp
3. Import settings:
   • Elevation: None
   • CRS: WGS84 latlon (also tried Web Mercator)
4. the import works
5. GIS > Export > Shapefile
6. Export settings: I tried all combinations
7. Error

I get the same error. Try using an old version of Blender. I will try it now and report back.

[ChameleonScales]

Indeed it works on Blender 2.93.4. I updated the title and description.

[Simple2Sample]

Yup. I tried it on 2.83 and it worked.

Is it ok now?

is blender 3.0 ok now??can it export a shp file?

[Simple2Sample]

I haven't tried it in 3.0. Try for yourself. If it doesn't work then you can simply use 2.83.

[Hareden]

我没有在3.0中尝试过。自己试试。如果它不起作用，那么你可以简单地使用2.83。

thanks to your reply. Actually i use blender 3.1 ,cause the same problem. i don`t have 2.83,it is difficult to download blender 2.83 in China because of my Internet.

why does blender 3.0 or 3.1 cause this problem? Did the Author give a result?

[Simple2Sample]

The only solution for now is to use something before 3.0. You could also modify the library yourself if you are capable of doing that.

[Hareden]

现在唯一的解决方案是使用3.0之前的东西。如果您有能力，您也可以自己修改库。

Thanks to your reply again! i will download blender 2.xxx and fix this add-ons again if i have time.
