[gdal-dev] Getting Polygon Vectors Out of a dwg File?

[Brandon Biggs]

Hello,

I am wondering how I can get polygon vectors out of a dwg file? Geojson is the easiest format for me to use, but I just need the data in something I can open that's not a picture so I can perform collision detection on the polygons. (apparently autocad is unable to export into any open formats).

I would prefer to use one of the existing applications to do a simple conversion from dwg to geojson, but I'm having trouble understanding the command line arguments and what application I need.

Since I want vector data, ogr2ogr<https://gdal.org/programs/ogr2ogr.html#ogr2ogr> looks like the application that I need.

The problem is I am not seeing any output file name in the argument list. I see update, append, and overwrite.

For the input file, I am only seeing dst_datasource_name, which I take to be my input. Dwg file.

Can someone please let me know what I am missing and if there is something else I should be reading?

Thank you,
