Issues with Hatch....

[Emmanuel Bardiere]

Hello Manfred,

I'am trying to transform 2 closed polylines (one external and one internal) as boundary with hatching.

My code is linked.
Where are my mistakes ?

Thank's again, this library is fantastic for me.

Regards, Emmanuel.

Hi!

I can not find any errors, I just colored the hatch red for better recognition.

from datetime import datetime


import ezdxf

import os


# Trying to have an hatch with hole.

now = datetime.now()
name = 'test_%d-%d-%d_%d.%d.%d'%(now.year,now.month,now.day,now.hour,now.minute,now.second)+'.dxf'

dwg = ezdxf.new('AC1015') # hatch requires the DXF R2000 (AC1015) format or later
msp = dwg.modelspace() # adding entities to the model space
dwg.layers.new('HATCH', dxfattribs={'linetype': 'Continuous', 'color': 8})


hatch = msp.add_hatch(color=253,dxfattribs={'layer': 'HATCH'})
hatch.set_pattern_fill('AR-CONC',scale=1.,angle=0,style=0,color=0)


with hatch.edit_boundary() as boundary:
 # every boundary path is always a 2D element
 boundary.add_polyline_path([(0, 0), (1000, 0), (1000, 1000), (0, 1000)], is_closed=1 , flags=1) # External
 boundary.add_polyline_path([(300, 300), (700, 300), (700, 700), (300, 700)], is_closed=1 , flags=16) # Internal
 

filePath, fileName = os.path.split(__file__)
dwg.saveas(filePath+os.sep+name)

from Source Code above, 

When open the DXF file,hatch in  dxf file will be solid, after I double-click to re-edit then can see the concrete pattern.
But If use small dimension of part, (10, 10),(3,3),(7,3) ...

Indeed, it's working with Autocad, but not with LibreCAD (on mac).

But it's working on Autocad, and it's the most important.

Thank you again, Emmanuel.
