Treatise on isometrical drawing : as applicable to geological and mining plans, picturesque delineations of ornamental grounds, perspective views and working plans of buildings and machinery, and to general purposes of civil engineering
Thomas Sopwith's 1838 treatise, published in London by John Weale, teaches isometric drawing for engineers, geologists and mine surveyors. Its plates show isometric plans of gardens and mining sites, with a few perspective views of buildings. For a designer, they are clear examples of how a three-dimensional site can be set out on a flat sheet using a fixed 30-degree isometric grid, with hatched sections and labelled plan figures.
