Release v0.8.6

News

• NEW: ezdxf project website: https://ezdxf.mozman.at/
• CHANGE: create all missing tables of the TABLES sections for DXF R12
• BUGFIX: entities on new layouts will be saved
• NEW: Layout.page_setup() and correct 'main' viewport for DXF R2000+; For DXF R12 page_setup() exists, but does not provide useful results. Page setup for DXF R12 is still a mystery to me.
• NEW: Table(), MText(), Ellipse(), Spline(), Bezier(), Clothoid(), LinearDimension(), RadialDimension(), ArcDimension() and AngularDimension() composite objects from dxfwrite as addons, these addons support DXF R12
• NEW: geometry builder as addons: MeshBuilder(), MeshVertexMerger(), MengerSponge(), SierpinskyPyramid(), these addons require DXF R2000+ (MESH entity)
• BUGFIX: fixed invalid implementation of context manager for r12writer

Paper Space Layout Page Setup

This release brings page setup for paper space layouts, at least for DXF R2000+, for DXF R12 I still don't know how page setup works.

layout = dwg.layouts.new('Layout2')
layout.page_setup(size=(297, 210), margins=(10, 15, 10, 15), units='mm')

This defines an ISO A4 page with a width of 297mm and a height of 210mm, and margin values in clockwise order: top-, right-, bottom- and left-margin. See also example file: examples/page_setup_R2000.py

Bugfix to save entities added to a paper space layout.

Add-ons Subpackage

the subpackage ezdxf.addons contains additional modules, functions and high level helper classes. The core ezdxf package stays independent from this addons.

For an easier transition from dxfwrite to ezdxf, I added the composite entities of dxfwrite as helper classes:

• Table(), a HTML table like entity, built from basic DXF entities
• MText(), a MTEXT like composite for DXF R12, rendering as TEXT entities
• Ellipse(), Spline(), Bezier(), Clothoid(): 2D curves, rendering as POLYLINE entities

Other helper classes in the subpackage ezdxf.addons:

• MeshBuilder(): simple helper class for building MESH objects, renders to MESH - but a POLYLINE (Polyface) renderer is planned
• MeshVertexMerger(): like MeshBuilder() but removes vertex doublets.
• MengerSponge(): just a show case entity, renders to a MESH entity
• SierpinskyPyramid(): just a show case entity, renders to a MESH entity

Tox

Because I forgot the audit subpackage in release v0.8.5 in setup.py, I have installed tox in my develop environment, to verify a complete install process. I also added the integration_tests and associated test data to the source install package which now has more than 1MB, but the wheel package still has less than 300kB.
