layers in DXF: turning on/off or freezing

[Pawel Banys]

Hello,

I have a small DXF file generated by some simple CAD program. You may take a
look at it below.

There are two layers used in the file:

some_layer_name_1
some_layer_name_2

Now the conversion programs indicate that all layers in that file have an
"on" status.

How should I modify that ascii dxf file in any text editor to turn off or
freeze the layer of my choice, for example "some_layer_name_2"?

Thank you for any help.

Pawel Banys
