A Python library to create DXF R12 drawings.
a simple example:
from dxfwrite import DXFEngine as dxf drawing = dxf.drawing('test.dxf') drawing.add(dxf.line((0, 0), (10, 0), color=7)) drawing.add_layer('TEXTLAYER', color=2) drawing.add(dxf.text('Test', insert=(0, 0.2), layer='TEXTLAYER')) drawing.save()
supported DXF R12 entities
- POLYLINE (special Polyface and Polymesh objects are available)
- SHAPE (not tested)
- VERTEX (only for internal use, see Polyline, Polyface and Polymesh objects)
not supported DXF R12 entities
emulated entities from DXF R13 and later
- MTEXT (R13) ... emulated as composite entity MText
- ELLIPSE (R13) ... approximated by Ellipse
- SPLINE (R13) ... approximated by Spline
- LWPOLYLINE (R13) ... use POLYLINE
- TABLE (R2005) ... emulated as composite entity Table
- MText -- multi-line text
- Table -- text and blockrefs containing table like a HTML-table
- Ellipse -- approximated as POLYLINE
- Spline -- cubic spline curve through breakpoints without additional control points, approximated as POLYLINE
- Bezier -- cubic bezier curve through breakpoints with additional control points, approximated as POLYLINE
- Clothoid -- Euler spiral, approximated as POLYLINE
read/write AutoCAD ctb-files
acadctb provides the ability to read and write AutoCAD ctb-files.
With ctb-files you can assign a new color or lineweight to a dxf-color-index for
plotting or printing, but this has to be supported by the used application.
a simple example:
from dxfwrite import acadctb ctb = acadctb.load('test.ctb') style1 = ctb.get_style(1) # dxf color index (1 .. 255) style1.set_color(23, 177, 68) # set rgb values (0..255) style1.set_lineweight(0.7) ctb.save('new.ctb')
pip install dxfwrite
or from source:
python setup.py install
