What is ezdxf¶
ezdxf is a Python package which allows developers to read existing DXF drawings or create new DXF drawings.
The main objective in the development of ezdxf was to hide complex DXF details from the programmer but still support all the possibilities of the DXF format. Nevertheless, a basic understanding of the DXF format is an advantage (but not necessary), also to understand what is possible with the DXF file format and what is not.
ezdxf is still in its infancy, therefore not all DXF features supported yet, but additional features will be added in the future gradually.
ezdxf is NOT¶
- ezdxf is not a DXF converter: ezdxf can not convert between different DXF versions, if you are looking for an appropriate program, use DWG TrueView from Autodesk, but the latest version can only convert to the DWG format, for converting between DXF versions you need at least AutoCAD LT.
- ezdxf is not a CAD file format converter: ezdxf can not convert DXF files to ANY other format, like SVG, PDF or DWG
- ezdxf is not a DXF renderer (see above)
- ezdxf is not a CAD kernel, ezdxf does not provide any functionality for construction work, it is just an interface to the DXF file format.
Supported Python Versions¶
ezdxf requires at least Python 2.7 and it’s Python 3 compatible. I run unit tests with CPython 2.7, the latest stable CPython 3 version and the latest stable release of pypy during development. ezdxf is written in pure Python and requires only pyparser as additional library beside the Python Standard Library, hence it should run with IronPython and Jython also.
Supported Operating Systems¶
ezdxf is OS independent and runs on all platforms which provide an appropriate Python interpreter (>=2.7).
Supported DXF Versions¶
|AC1012||AutoCAD R13 -> R2000|
|AC1014||AutoCAD R14 -> R2000|
ezdxf reads also older versions but saves it as R12.
Embedded DXF Information of 3rd Party Applications¶
The DXF format allows third-party applications to embed application-specific information. ezdxf manages DXF data in a structure-preserving form, but for the price of large memory requirement. Because of this, processing of DXF information of third-party applications is possible and will retained on rewriting.
