exoport to dxf

Hi everybody,

I have a sheet metal part with 2 sketches, sketch A and sketch B.

I am going to export the part to DXF file, but I need the sketch A to be exported to DXF but sketch B not to export.

Is there any way to prevent sketch B from exporting to DXF file EXCEPT suppressing the sketch B?

Thanks
