Is it possible to defined a filled circle/ellipse?

[johnthagen]

When I create a regular circle using add_circle() and view it in a DXF viewer:

It is not filled. I've created lwpolylines and hatchs that are filled and I'd like to define regular circles as filled as well.

Does DXF support something like this?

You have to create a HATCH with an EdgePath as boundary.

See HATCH tutorial, 3rd example: https://ezdxf.mozman.at/docs/tutorials/hatch.html

import ezdxf

doc = ezdxf.new("R2000")
msp = doc.modelspace()
msp.add_ellipse((0, 0), major_axis=(0, 10), ratio=0.5)

hatch = msp.add_hatch(color=2)
edge_path = hatch.paths.add_edge_path()

# each edge path can contain line, arc, ellipse and spline elements
# important: major axis >= minor axis (ratio <= 1.)
edge_path.add_ellipse((0, 0), major_axis=(0, 10), ratio=0.5)

doc.saveas("solid_hatch_ellipse.dxf")

• line EdgePath.add_line()
• arc EdgePath.add_arc()
• ellipse EdgePath.add_ellipse()
• spline EdgePath.add_spline()
