A curated working library for the design studio — CAD blocks, BIM families, construction details, climate data, building codes, and live calculators. Built by architects, for the drawings on your desk today.
CAD blocks, construction details, BIM families, title-block templates, and material specs — organised, tagged, and downloadable in the formats you actually use.
Stair geometry, scale-to-paper, solar altitude, area & volume, unit conversion, parking demand — all reactive, all in-browser, no spreadsheet required.
IBC, IRC, Eurocode, NEN, DIN — current editions, status flags, and scope notes. Find the right reference before you draw, not after.
Identify yourself to access the working library and tools.
