News

Version 0.8.4 - 2017-02-19

  • dxfgrabber can read DXF files with only an ENTITIES section

Version 0.8.3 - 2017-02-06

  • BUGFIX: handles windows line ending ‘rn’ in streams correct, some streams do not produce universal line endings

Version 0.8.2 - 2017-01-22

Version 0.8.1 - 2016-08-17

  • BUGFIX: restored VERTEX bulge values
  • NEW: excepts ‘inf.0’ and ‘-inf.0’ float values created by QGIS (AutoCAD does not read this none standard values)

Version 0.8.0 - 2016-04-24

  • internal refactoring - removed extra layer for DXF R12 and DXF R13 implementation
  • removed parts implemented in Cython
  • new version is ~30% faster than the old pure Python version but ~15% slower than the version with C-extension
  • some pep8 refactorings, renamed attributes like startparam to start_param

Version 0.7.5 - 2015-11-29

  • Python only version runs with CPython (2.7, 3.4, 3.5), pypy-5.0.0 and pypy3-2.4.0
  • accepts block definitions without explicit base point, defaults to (0, 0, 0)
  • NEW: reads DXF versions older than AC1009 (DXF R12), as far I know, I need more old files for testing
  • KNOWN BUG: Win7 and Python 2.7.10 - can’t build Cython extension with MingW32, use Python 2.7.9 instead
  • KNOWN BUG: Win7 and Python 3.5.0 - can’t build Cython extension with MingW32 but work with VC2015

Version 0.7.4 - 2014-05-23

  • NEW: added support for R12 2d splines (by POLYLINE); POLYLINE.mode == “spline2d”
  • NEW: TEXT.plain_text(), removes format codes like &&u and transforms %%d to °
  • BUGFIX: unicode/str error in Cython extension for Python 2.7
  • BUGFIX: every LWPolyline in DXF version > AC1009 had default thickness of 0.0
  • BUGFIX: Polyline.width had incorrect values

Version 0.7.3 - 2014-05-16

  • NEW: options = {"assure_3d_coords": True}, guarantees (x, y, z) tuples for ALL coordinates, this option is by default False
  • NEW: extended TrueColor() class, see docs
  • NEW: dxfgrabber.aci_to_true_color(index) returns the DXF default true color value for AutoCAD Color Index index as TrueColor()
  • NEW: added is_backwards, is_upside_down, width, oblique, font, bigfont attributes to TEXT, ATTRIB, ATTDEF entities
  • NEW: added plain_text() method to TEXT, ATTRIB and ATTDEF to get text content without formatting codes like ‘%%u’
  • NEW: added font, bigfont, rect_width, horizontal_width and vertical_height attributes to MTEXT
  • NEW: added resolve_text_styles(text_styles) method to TEXT, ATTRIB, ATTDEF, MTEXT entities
  • NEW: new import option “resolve_text_styles” and it is True by default
  • NEW: added extrusion direction to all entities
  • NEW: added row_count, col_count, row_spacing, col_spacing attributes to INSERT.
  • NEW: MText.plain_text(split=False) tries to remove format codes, returns a single string or a list of strings
  • NEW: added n_smooth_density, m_smooth_density, smooth_type to Polymesh
  • NEW: added smooth_type to Polyface
  • CHANGE: LWPolyline again: LWPolyline.points list of (x, y) or (x, y, z) depends on “assure_3d_coords”, LWPolyline.width list of (start-width, end-width), .bulge list of floats, removed LWPolyline.get_rstrip_points() and added .const_width attribute (if != 0, ignore .width list).
  • CHANGE: Polyline method points() is now a field (list) and added lists for width and bulge for consistent APIs of LWPolyline and Polyline.
  • BUGFIX: wrong DXF subclass for Arc.extrusion (error in DXF Standard)

Version 0.7.2 - 2014-05-09

  • NEW: grabs SAB data of BODY, 3DSOLID, … entities for DXF version AC1027 (R2013) and later
  • NEW: support for dxf attributes: true_color (AC1018), transparency (AC1018), shadow_mode (AC1021) in prior DXF versions this attributes are set to None.
  • NEW: using Cython for some speed optimizations, but Cython is not a installation requirement; control the Cython extension by environment variable DXFGRABBER_CYTHON = ON|OFF, by default the Cython extension is activated.
  • CHANGED: LWPolyline.points are always 5-tuples (x, y, start_width, end_width, bulge)
