A Python library to create DXF R12 drawings.

Project description

dxfwrite

Abstract

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

  • ARC
  • ATTDEF
  • ATTRIB
  • BLOCK
  • CIRCLE
  • 3DFACE
  • INSERT
  • LINE
  • POINT
  • POLYLINE (special Polyface and Polymesh objects are available)
  • SHAPE (not tested)
  • SOLID
  • TRACE
  • TEXT
  • VERTEX (only for internal use, see Polyline, Polyface and Polymesh objects)
  • VIEWPORT

not supported DXF R12 entities

  • DIMENSION

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

composite entities

  • MText – multi-line text
  • LinearDimension
  • AngularDimension
  • ArcDimension
  • RadialDimension
  • 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

The module 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')

Installation

with pip:

pip install dxfwrite

or from source:

python setup.py install
