Template:Layered blueprint/doc

This template allows compacting multiple layers of BlockGrids, in order save space, and better visualise a structure.

Usage
Each layered blueprint requires a unique name, a set of single-letter abbreviations for each image being used (same as BlockGrid), then a layer title and layer art pair.

A layer title is an anonymous parameter starting with, then the layer's name. Layer art is defined similar to BlockGrid, except the entire layer is a single anonymous parameter, instead of separate ones for each line. Empty lines should contain at least a single space, otherwise they may be removed.

The layer which is selected by default can be changed by setting to the desired layer's name.
