The carpenter's new guide: being a complete book of lines for carpentry and joinery. Treating fully on practical geometry, soffits, brick and plaster groins ... with a great variety of designs for roofs, trussed girders ... with many other things entirely new: the whole founded on true geometrical principles; the theory and practice well explained and fully exemplified on eighty-four copper-plates; including some observations and calculations on the strength of timber
A builder's manual of practical geometry for carpenters and joiners by Peter Nicholson, first issued in Britain in 1792 and reprinted in Philadelphia by J. Grigg in 1830 for working tradesmen and apprentices. The eighty-four copper-plates set out roofs, groined vaults, soffits and trussed girders as line diagrams with lettered points, arcs and hatched or wash-shaded timbers usable as technical ornament.
