I am working on a project to extract data from DXF files using ezdxf and Shapely.
In some DXF files, the extraction works correctly, but in other files it does not.

The issues seem to vary depending on how the DXF is authored (layers, LINE vs LWPOLYLINE, open boundaries, units, etc.).

Questions:

1. How can I make DXF data extraction more robust so it works across different drawings?

2. What are the common edge cases I should handle when extracting geometry from DXF files?

3. Are there any alternative libraries or technologies (besides ezdxf) that can parse DXF files more reliably?

I am particularly interested in extracting:

• Plot boundaries

• Building footprints

• Areas and distances (e.g., setbacks)

Any best practices or recommendations would be appreciated.
