adding XDATA to dxf files

[ohit...@mail.ru]

Hi!

I need to add some xdata (hyperlinks) to acad entities.

code:

import ezdxf

from collections import namedtuple

dwg = ezdxf.new('AC1027')

ms = dwg.modelspace()

DXFTag = namedtuple('DXFTag', 'code value')

c = ms.add_circle((10,10), 100)

c.tags.new_xdata('PE_URL', [DXFTag(code=1000, value='tralivali.ru'), DXFTag(code=1002, value='{'), DXFTag(code=1000, value='tralivali'),

                 DXFTag(code=1002, value='{'), DXFTag(code=1071, value=1), DXFTag(code=1002, value='}'), DXFTag(code=1002, value='}')])

dwg.saveas('2013_new.dxf')

But when i added xdata to circle file stops to open in acad. I get an error:

Premature end of object 

invalid or incomplete DXF input -- drawing discarded. 

Press ENTER to continue

Without xdata file opens normally

Can anybody help me to decide this problem?

Hi!

AutoCAD 2015 crashed without an error message!

Solution: create an APP ID entry for "PE_URL"

import ezdxf

from ezdxf.lldxf.tags import DXFTag

dwg = ezdxf.new('AC1027')

dwg.appids.new('PE_URL')  # create APP ID entry

ms = dwg.modelspace()

c = ms.add_circle((10, 10), 100)

c.tags.new_xdata('PE_URL',

                 [

                     DXFTag(1000, 'tralivali.ru'),

                     DXFTag(1002, '{'),

                     DXFTag(1000, 'tralivali'),

                     DXFTag(1002, '{'),

                     DXFTag(1071, 1),

                     DXFTag(1002, '}'),

                     DXFTag(1002, '}')

                 ])

dwg.saveas('xdata.dxf')

This works with AutoCAD 2015, but I don't know how to test if AutoCAD recognized the XDATA.

UPDATE: ezdxf 0.7.7 - Entity.tags.new_xdata() and Entity.tags.set_xdata() accept tuples as tags, no import of DXFTag required

import ezdxf

dwg = ezdxf.new('AC1027')

dwg.appids.new('PE_URL')  # create APP ID entry

ms = dwg.modelspace()

c = ms.add_circle((10, 10), 100)

c.tags.new_xdata('PE_URL',

                 [

                     (1000, 'tralivali.ru'),

                     (1002, '{'),

                     (1000, 'tralivali'),

                     (1002, '{'),

                     (1071, 1),

                     (1002, '}'),

                     (1002, '}')

                 ])

dwg.saveas('xdata.dxf')

Thank you! Your module is great, now i'm free from autocad and can make drawings only with python (and your module of cource :) )!
