GDAL (ogr2ogr) generated DXF line weight problem

Hi, different question for the same original DXF file...

We are using your Pro product (qcad-3.26.1-pro-linux-x86_64) on Ubuntu 20.04 LTS.

We made a converted (reprojected) DXF file using ogr2ogr by GDAL:

Code: Select all

ogr2ogr -skipfailures -f DXF -s_srs EPSG:5186 -t_srs EPSG:3857 test_ogr2ogr.dxf test.dxf

test_ogr2ogr.dxf

The problem is, that converted lines does not seem to reflect Lineweight properly.

This is the original DXF and I applied 2.11mm Lineweight:

This is the original DXF and I applied 2.11mm Lineweight for the same line (polyline precisely, because ogr2ogr redraws everthing in polylines regardless of the original type)
As you can see, line is still so thin even if 2.11mm applied (but it is a bit thicker than normal lines):

Is there any configuration that I am missing?

Note that the drawing unit of the original file is Millimeter and the converted file is Inch.

That's right! so GDAL somehow changed the property of the DXF file...thanks a lot!
