I am able to write dxf file using Python ezdxf function which can generate a square. But I want to draw another smaller square and want to to subtract it from bigger square to get an annular ring. How can I do that using ezdxf function?
Here is my code which can generate square hatch using ezdxf and write it into a DXF file.
import ezdxf
doc = ezdxf.new("R2010") # create a new DXF drawing (AutoCAD 2010)
msp = doc.modelspace() # we are working in model space
msp.add_line((10, 10), (0, 10))
msp.add_line((0, 10), (0, 0))
msp.add_line((0, 0), (10, 0))
msp.add_line((10, 0), (10, 10))
doc.saveas("hatch_with_spline_edge.dxf") # save DXF drawing
