The idea of creating blueprints to copy from using parchment and pigments is great to begin with. As for the actual copying itself; just reuse the clay forming mechanic's way of "copying" a layer. Still takes time, still drains chisel durability like crazy, as every voxel is chiseled one after the other (or maybe in steps of 4 at once like clay forming) but reduces the tedium of having to manually chisel the same shape of 1/16 grid custom fence pieces about 100 times (totally not speaking from experience.)
