I notice that once you add footprint(from *.MOD) to part you received all shapes from all non-signal(not copper) layers on a single layer. And it looks like everything is on the silkscreen layer right now.
But this is wrong. I don't need all these lines on PCB I need only shapes from the silkscreen layer(if you open MOD file the silkscreen will be layer "21").
Yes, during PCB design I need mechanical(in KiCAD these layers are called ECO or "Engineering Change Order") layers to understand what I have between these pads, but I will not send it to a PCB manufacturer.
I think we are losing information about layers, we can't separate the silkscreen layer's shapes from other layers. Also, we don't have solder mask and paste mask layers at all.
