Hello Team,

I have written below code for drawing dxf file but when I was opening the the python generated dxf file into AutoCAD I had to done grouping of all the elements. Can you please let me know what I am missing in my code so that grouping issue could be resolved. Thanks.

import ezdxf

# doc = ezdxf.new('R2010') # create a new DXF R2010 drawing, official DXF version name: 'AC1024'

doc = ezdxf.new('R2010', setup=True)

msp = doc.modelspace() # add new entities to the modelspace

####### Tank 1 ###########

msp.add_line((0, 0), (10, 0))

msp.add_line((0, 10), (0, 0))

msp.add_line((0, 10), (10, 10))

msp.add_line((10, 10), (10, 0))

msp.add_arc(

center=(5, 10),

radius=5.0,

start_angle=0,

end_angle=180,

dxfattribs={'layer': 'arc'},

)

####### Tank 2 ###########

msp.add_line((50, 0), (60, 0))

I don't understand your question. What do you mean by "I had to done grouping of all the elements".
