Release v0.9

News

• IMPORTANT: Python 2 support REMOVED, if Python 2 support needed: add ezdxf<0.9 to your requirements.txt
• NEW: testing on Manjaro Linux in a VM by tox
• CHANGE: converted NEWS.rst to NEWS.md and README.rst to README.md
• CHANGE: moved Importer() from ezdxf.tools to ezdxf.addons - internal structures of modern DXF files are too complex and too undocumented to support importing data in a reliable way - using Importer() may corrupt your DXF files or just don't work!
• NEW: type annotations to core package and add-ons.
• NEW: argument setup in ezdxf.new('R12', setup=True) to setup default line types, text styles and dimension styles, this feature is disabled by default.
• NEW: Duplicate table entries: dwg.styles.duplicate_entry('OpenSans', new_name='OpenSansNew'), this works for all tables, but is intended to duplicate STYLES and DIMSTYLES.
• CHANGED: replaced proprietary fonts in style declarations by open source fonts
• NEW: open source fonts to download https://github.com/mozman/ezdxf/tree/master/fonts
• OpenSansCondensed-Light font used for default dimension styles
• NEW: subpackage ezdxf.render, because of DIMENSION rendering
• NEW: support for AutoCAD standard arrows
• NEW: support for creating linear DIMENSION entities
• NEW: background color support for MTEXT
• CHANGE: DXF template cleanup, removed non standard text styles, dimension styles, layers and blocks
• CHANGE: text style STANDARD uses txt font
• CHANGE: renamed subpackage ezdxf.algebra to ezdxf.math
• CHANGE: moved addons.curves to render.curves
• CHANGE: moved addons.mesh to render.mesh
• CHANGE: moved addons.r12spline to render.r12spline
• CHANGE: moved addons.forms to render.forms
• CHANGE: renamed construction helper classes into Construction...()
• Ray2D() renamed to ConstructionRay()
• Circle() renamed to ConstructionCircle()
• Arc() renamed to ConstructionArc()
• NEW: construction tools ConstructionLine() and ConstructionBox()
• REMOVED: almost_equal use math.isclose
• REMOVED: almost_equal_points use ezdxf.math.is_close_points
• BUGFIX: closed LWPOLYLINE did not work in AutoCAD (tag order matters), introduced with v0.8.9 packed data structure
• BUGFIX: UCS.to_ocs_angle_deg() corrected

Python 2

Python 2 support dropped

Dimension

Support for linear dimension (more dimension types to come), but I have no time to write a documentation now, please look at the script dimensions_linear.py for many examples. DIMENSION works with DXF R12, but you will get better results with DXF R2000 and later.

Linux

Run tests by tox on Manjaro Linux in an VM on VirtualBox.

Fonts

Replaced all fonts by open source fonts.
