 I believe the "Mechanical/HVAC layer“ refers to the virtual layer in a CAD program or a layer shown in a set of blueprints for a building. Often different utilities are seperated out into separate layers or drawings to avoid confusion of different piping or electrical utilities such as water, gas, sewage, electrical, hvac, etc. See https://blog.draftsperson.net/iso-13567-cad-layer-standard/ for reference.

	:I've gone in and altered the last paragraph (it looks like the author of that wasn't too concerned about the near-similar thicknesses of the sliced-through strata, but I presume that it was a basic measurement and calculation of the relative radii of innermost and outermost spheres that came to the 900km conclusion). A very quick glance didn't suggest anything about the similar thicknesses in the list (may have missed it, it was a ''very very'' quick read-through!), but note that there ''is'' obvious variation, belying it being a "just line 'em up regularly" diagram but maybe just happens to be semi-accurately representing a semi-similar set of thicknesses. Because sometimes the things just turn out to be semi-regular like that, maybe? (Ok, so it's in a fiction/imagination, already, but if we're not allowed to be meta in xkcd then where else can one?)
