dxf2code¶

Translate DXF entities and structures into Python source code.

Short example:

import ezdxf
from ezdxf.addons.dxf2code import entities_to_code, block_to_code

doc = ezdxf.readfile('original.dxf')
msp = doc.modelspace()
source = entities_to_code(msp)

# create source code for a block definition
block_source = block_to_code(doc.blocks['MyBlock'])

# merge source code objects
source.merge(block_source)

with open('source.py', mode='wt') as f:
    f.write(source.import_str())
    f.write('\n\n')
    f.write(source.code_str())
    f.write('\n')

ezdxf.addons.dxf2code.entities_to_code(entities: Iterable[DXFEntity], layout: str = 'layout', ignore: Iterable[str] | None = None) → Code¶

Translates DXF entities into Python source code to recreate this entities by ezdxf.

Parameters:

entities – iterable of DXFEntity
layout – variable name of the layout (model space or block) as string
ignore – iterable of entities types to ignore as strings like ['IMAGE', 'DIMENSION']

Returns:

Code

ezdxf.addons.dxf2code.block_to_code(block: BlockLayout, drawing: str = 'doc', ignore: Iterable[str] | None = None) → Code¶

Translates a BLOCK into Python source code to recreate the BLOCK by ezdxf.

Parameters:

block – block definition layout
drawing – variable name of the drawing as string
ignore – iterable of entities types to ignore as strings like [‘IMAGE’, ‘DIMENSION’]

Returns:

Code

ezdxf.addons.dxf2code.table_entries_to_code(entities: Iterable[DXFEntity], drawing='doc') → Code¶

ezdxf.addons.dxf2code.black(code: str, line_length=88, fast: bool = True) → str¶

Returns the source code as a single string formatted by Black

Requires the installed Black formatter:

pip3 install black

Parameters:

code – source code
line_length – max. source code line length
fast – True for fast mode, False to check that the reformatted code is valid

Raises:

ImportError – Black is not available

class ezdxf.addons.dxf2code.Code¶

Source code container.

code¶: Source code line storage, store lines without line ending \\n

imports¶: source code line storage for global imports, store lines without line ending \\n

layers¶: Layers used by the generated source code, AutoCAD accepts layer names without a LAYER table entry.

linetypes¶: Linetypes used by the generated source code, these linetypes require a TABLE entry or AutoCAD will crash.

styles¶: Text styles used by the generated source code, these text styles require a TABLE entry or AutoCAD will crash.

dimstyles¶: Dimension styles used by the generated source code, these dimension styles require a TABLE entry or AutoCAD will crash.

blocks¶: Blocks used by the generated source code, these blocks require a BLOCK definition in the BLOCKS section or AutoCAD will crash.

code_str(indent: int = 0) → str¶

Returns the source code as a single string.

Parameters:: indent – source code indentation count by spaces

black_code_str(line_length=88) → str¶

Returns the source code as a single string formatted by Black

Parameters:: line_length – max. source code line length
Raises:: ImportError – Black is not available

import_str(indent: int = 0) → str¶

Returns required imports as a single string.

Parameters:: indent – source code indentation count by spaces

merge(code: Code, indent: int = 0) → None¶: Add another Code object.

add_import(statement: str) → None¶: Add import statement, identical import statements are merged together.

add_line(code: str, indent: int = 0) → None¶: Add a single source code line without line ending \n.

add_lines(code: Iterable[str], indent: int = 0) → None¶: Add multiple source code lines without line ending \n.
