There are = packaged types and layout group types and the rest is simply materials = attribs of something-on-insulator. I think the easiest way forward is = layers model something-on-insulator, and the something can be on one = side only, and that side can be oriented up or down. Too much of a short cut for me. What about boards with steel layers? = They=92re not insulators, but they also don=92t fit your plated-on = model. Nor, really, do soldermask and so-called =93silk=94. Why not actually use =93layer=94 with its meaning in English? Is that = really so hard? As for =93drawing layers=94, let me suggest that = =93pattern sets=94 is a much clearer, more correct term.
