#define SILK_LAYER 2

Layer Stack.

The situation is not ideal, because on top of the ordinary layer stack there are two (both) silk layers. It was a hack to separate these and probably done to easier iterate through non-silk layers, only. As we have layer types now, iterating through any kind of distinct layer type has become simple, see LAYER_TYPE_LOOP() in macro.h.

Accordingly, the separation of these two silk layers should go away, they should return to be "normal" layers. One might want to have more than two silk layers, after all.

Anyways, here's the current setup:

Copper layer 0 \ Copper layer 1 | Outline layer >- in unspecified order Routing layer | (...additional layers...) / <== max_copper_layer Bottom silk layer Top silk layer <== max_copper_layer + SILK_LAYER (...unused layers...) (last layer - 2) <== MAX_LAYER (last layer - 1) (last layer) <== MAX_ALL_LAYER ( == MAX_LAYER + SILK_LAYER)

With all layers in use (rarely the case), max_copper_layer == MAX_LAYER.

Note:: Position on the layer stack does not decide whether a layer is on the top side, on the bottom side or in between. Each layer is part of a layer group, and this group represents the physical layer, like top, inner or bottom.
