conversione in dwg e layer lsd-0

[jim78b]

I don't understand why if the lines in the cartiglio check the layer 0 . then in the conversion model in dwg add to the layer 0 the visible sketch lines when I open the dwg everything that is on the layer 0 puts it on a layer created by sldwx: sld-0? I still can't chase all the lines and put them on any layer would be madness!. leave so ? because I have various sheet format templates e.g.
English a3 with welded notes
a3 ita with welding notes
a2 English with notes welds and so every time I have to change something I have to chase all the carts ... is there a faster method?
