A Python package to create/manipulate DXF drawings.
Project description
ezdxf
Abstract
A Python package to create and modify DXF drawings, independent from the DXF version. You can open/save every DXF file without loosing any content (except comments), Unknown tags in the DXF file will be ignored but preserved for saving. With this behavior it is possible to open also DXF drawings that contains data from 3rd party applications.
Quick-Info
ezdxf is a Python package to read and write DXF drawings
intended audience: Developer
requires Python 2.7 or later, runs on CPython and pypy, maybe on IronPython and Jython
OS independent
additional required packages: pyparsing
MIT-License
supported DXF versions: R12, R2000, R2004, R2007, R2010 and R2013
preserves third-party DXF content
a simple example:
import ezdxf drawing = ezdxf.new(dxfversion='AC1024') modelspace = drawing.modelspace() modelspace.add_line((0, 0), (10, 0), dxfattribs={'color': 7}) drawing.layers.create('TEXTLAYER', dxfattribs={'color': 2}) modelspace.add_text('Test', dxfattribs={'insert': (0, 0.2), 'layer': 'TEXTLAYER'}) drawing.saveas('test.dxf')
Installation
Install with pip:
pip install ezdxf
or from source:
python setup.py install

News
Version 0.6.0 - 2014-04-25
Beta status
Supported Python versions: CPython 2.7, 3.4 and pypy 2.2.1
Refactoring of internal structures
CHANGE: appended entities like VERTEX for POLYLINE and ATTRIB for INSERT are linked to the main entity and do not appear in layouts, model space or blocks (modelspace.query(‘VERTEX’) is always an emtpy list).
CHANGE: refactoring of the internal 2D/3D point representation for reduced memory footprint
faster unittests
BUGFIX: opens minimalistic DXF12 files
BUGFIX: support for POLYLINE new (but undocumented) subclass names: AcDbPolyFaceMesh, AcDbPolygonMesh
BUGFIX: support for VERTEX new (but undocumented) subclass names: AcDbFaceRecord, AcDbPolyFaceMeshVertex, AcDbPolygonMeshVertex, AcDb3dPolylineVertex
CHANGE: Polyline.get_mode() returns new names: AcDb2dPolyline, AcDb3dPolyline, AcDbPolyFaceMesh, AcDbPolygonMesh
CHANGE: separated layout spaces - each layout has its own entity space
Version 0.5.2 - 2014-04-15
Beta status
Supported Python versions: CPython 2.7, 3.3, 3.4 and pypy 2.2.1
BUGFIX: ATTRIB definition error for AC1015 and later (error in DXF specs)
BUGFIX: entity.dxf_attrib_exists() returned True for unset attribs with defined DXF default values
BUGFIX: layout.delete_entity() didn’t delete following data entities for INSERT (ATTRIB) & POLYLINE (VERTEX)
NEW: delete all entities from layout/block/entities section
cleanup DXF template files
Version 0.5.1 - 2014-04-14
Beta status
Supported Python versions: CPython 2.7, 3.3, 3.4 and pypy 2.2.1
BUGFIX: restore Python 2 compatibility (has no list.clear() method); test launcher did not run tests in subfolders, because of missing __init__.py files
Version 0.5.0 - 2014-04-13
Beta status
BUGFIX: Drawing.get_layout_setter() - did not work with entities without DXF attribute paperspace
NEW: default values for DXF attributes as defined in the DXF standard, this allows usage of optional DXF attributes (with defined default values) without check of presence, like entity.dxf.paperspace.
NEW: DXF entities Shape, Ray, XLine, Spline
NEW: delete entities from layout/block
CHANGE: entity 3DFACE requires 3D coordinates (created by add_3Dface())
CHANGE: LWPolyline all methods return points as (x, y, [start_width, [end_width, [bulge]]]) tuples
updated docs
Version 0.4.2 - 2014-04-02
Beta status
Supported Python versions: CPython 2.7, 3.3, 3.4 and pypy 2.1
NEW: DXF entities LWPolyline, MText
NEW: convenience methods place(), grid(), get_attrib_text() and has_attrib() for the Insert entity
CHANGE: pyparsing as external dependency
BUGFIX: iteration over drawing.entities yields full functional entities (correct layout attribute)
BUGFIX: install error with pip and missing DXF template files of versions 0.4.0 & 0.4.1
Version 0.3.0 - 2013-07-20
Alpha status
Supported Python versions: CPython 2.7, 3.3 and pypy 2.0
NEW: Entity Query Language
NEW: Import data from other DXF files
CHANGE: License changed to MIT License
Version 0.1.0 - 2010-03-14
Alpha status
