## What it is
ezdxf is a Python package for creating, reading, modifying and writing DXF (AutoCAD) documents across DXF versions R12 through R2018, including ASCII and binary formats. It preserves third-party content, ships optional C-extensions for speed, and includes add-ons for rendering, streaming huge files, and a CLI for inspecting DXF files.

## Use cases
- create dxf files programmatically in python
- read and edit autocad dxf drawings without losing content
- convert dxf files to png, pdf or svg images
- process huge dxf files larger than memory
- inspect and audit dxf files from the command line
- extract entities from cad drawings for analysis
- generate parametric dxf entities from python code

## When to choose
- you need to programmatically create, edit or parse DXF files in Python
- you must preserve unknown third-party DXF tags when round-tripping documents
- you need to render or convert DXF drawings to images or vector formats
- you work with very large DXF files that don't fit in memory

## When to avoid
- you need a GUI CAD editor rather than a programming library
- you need to write DWG files (ezdxf handles DXF only)
- you need read/write support for DXF versions older than R12

## Facets
- artifact type: library
- maturity: stable
- function: parser, file-system, data-visualization, cli
- domain: files, developer-tools, graphics
- platform: python, cross-platform, cli
- tags: dxf, cad, autocad, caddrawing, geometry, rendering, automation
