- This page contains ideas for possible new features in future versions of `ezdxf`.
-
- # Add-ons
- ## `drawing` add-on improvements
- LATER Support for `Layout.dxf.plot_layout_options` in export mode of class `RenderContext`
- plot with plot-styles
- disable loading of the ctb-table in `set_current_layout()`
- plot entity lineweights
- if disabled which linewidth should be used instead?
- scale lineweights
- scale by what?
- plot transparencies
- hide paperspace entities (`DXFGraphic.dxf.paperspace` attribute is `True`)
- [[VIEWPORT]] borders are not plotted at all by the `drawing` add-on
- LATER improve linetype rendering of wide patterns, see [#906](https://github.com/mozman/ezdxf/issue/906)
-
- ## DWG loader add-on
- #maybe a DWG loader for simple documents
- useful for scenarios where the [[ODA File Converter]] is not available
- can not replace the [[ODA File Converter]] application, but maybe good enough for simple documents
- Cython will be required for the low level stuff, no pure Python implementation.
-
- # DXF Entities
- LATER [[GEODATA]] version 1 support, see mpolygon examples and DXF reference R2009
- LATER explode [[HATCH]] pattern into [[LINE]] entities, points are represented by zero-length [[LINE]] entities, because the [[POINT]] entity has a special meaning.
- LATER [[HATCH]] - move hatch pattern origin
- examples/entities/hatch_pattern_modify_origin.py
- {{discussion 769}}
- #maybe add support for [[REGION]] entities:
- A [[REGION]] consist of one or more flat loops that enclose a space based on [[ACIS]].
- The [[SAT]] and [[SAB]] representation of curved edges and faces within [[ACIS]] data needs to be reverse engineered.
- Explode curved faces into virtual [[LINE]], [[ARC]], [[ELLIPSE]] and [[SPLINE]] entities or a [[Path]] instance
- #maybe associative arrays, [ARRAY](https://help.bricsys.com/document/_commandreference--CMD_-array/V23/EN_US?id=165079036414) command in CAD applications
-
- # Boundary Path Constructor
- LATER A module to create boundary paths for [[HATCH]] and [[MPOLYGON]] entities.
- The input data are DXF entities e.g. the result of a selection or an entity query, the module functions and classes help to detect closed path in the entity collection and returns one or more [[BoundaryPaths]] instances.
- Although [[HATCH]] and [[MPOLYGON]] can contain multiple separated areas in a single entity this module should create a boundary path for each separated area.
- All entities have to be located in the xy-plane and in a later version maybe in the same spatial plan defined by the extrusion vector and elevation.
- When the entities are located in the xy-plane the extrusion vector of [[CIRCLE]], [[ARC]] and [[ELLIPSE]] can be inverted.
- Simple closed paths
- [[CIRCLE]]
- full 360° [[ARC]]
- full 360° [[ELLIPSE]]
- closed [[LWPOLYLINE]] or 2D [[POLYLINE]]
- closed [[SPLINE]]
- [[SOLID]], [[TRACE]], [[3DFACE]]
- #maybe subtract [[TEXT]], [[ATTRIB]] and [[MTEXT]] as text box paths
- Complex connected paths are build from multiple entities, input entities can be
- [[LINE]]
- open [[ARC]]
- open [[ELLIPSE]]
- open [[LWPOLYLINE]] or 2D [[POLYLINE]]
- open [[SPLINE]]
- The path detection
- try to connect path elements by their closest end points
- by ambiguity the differnt possible paths are tracked recursively and the shortest
or longest path will be taken.
- A gap tolerance is given by the user to connect end points that are not coincident and the algorithm adds connection lines between these gaps.
-
- # Increase Minimal Required Python Version
- In general `numpy` defines the minimal required Python version.
-
- Python 3.10 in late 2024, after release of Python 3.13
- https://docs.python.org/3/whatsnew/3.10.html
- structural pattern matching?
- typing: union operator `|`, outside of annotations (type aliases)
- dataclasses: `__slots__`
-
- Python 3.11 in late 2025, after release of Python 3.14
- https://docs.python.org/3/whatsnew/3.11.html
- `typing.Self`
- `typing.overload()` decorator
-
- Python 3.12 in late 2026, after release of Python 3.15
- https://docs.python.org/3/whatsnew/3.12.html
- `typing.override()` decorator
- type parameter syntax: `def max[T](args: Iterable[T]) -> T: ...`
- use `type` for type aliases: `type Point = tuple[float, float]`
-
- Apply minimal Python version update to
- pyproject.toml
- README.md
- toplevel index.rst
- introduction.rst
- setup.rst
