Ticket #5705 – Description
initial v1 4 4 ogr2ogr -f "DXF" sampleb_output.dxf sampleb_input.dxf 5 5 6 The result I obtain is wrong (attached file "sampleb_output.dxf"). Basically, one the ellipses in the output has a wrong angle and its X coordinates are wrong.6 The result I obtain is wrong (attached file "sampleb_output.dxf"). Basically, one of the ellipses in the output has a wrong angle and its X coordinates are wrong. 7 7 8 Doing some investigation inside the input DXF, I saw that the ellipse that converts correctly has a Z extrusion axis value (group code 230) of 1.0, whereas the ellipse that was not converted correctly has a Z extrusion axis value of -1.0. I have done a test when I changed reverse its Z extrusion axis (to 1.0) and added Pi/2 to the start and end angles (41 and 42) in attached file "sampleb_input-mod.dxf". Then the conversion of the previously incorrect ellipse is done correctly (attached file "sampleb_output-mod.dxf").8 Doing some investigation inside the input DXF, I saw that the ellipse that converts correctly has a Z extrusion axis value (group code 230) of 1.0, whereas the ellipse that was not converted correctly has a Z extrusion axis value of -1.0.
