About this block
Five legends of CAD symbols share one sheet, each under its own heading. INSTALACIÓN HIDROSANITARIA covers pipe line types for cold, hot and return water, steam, fire main and gas, then globe, gate and check valves, plan fittings such as elbows up and down and tees, and an abbreviation list — B.A.N, C.A.F, R.A.C and the rest. INSTALACIÓN ELÉCTRICA follows with outlets, switches, bells, aerial and telephone points and named luminaires. Then LP gas, irrigation, and a finishes key: 279 captions in 972 entities.
The irrigation block is unusual in a general legend: pop-up sprays at 90, 180, 270 and 360 degrees, rotors, drippers and throw radii of 2.00, 3.50 and 6.00. The finishes key is a build-up table for MURO, PISO, BÓVEDA, AZOTEA and COLUMNAS, numbering each layer from base element to final finish, with a triangle marking a change of finish. A pipe note converts nominal diameters: 2 inch to 50 mm, 4 to 100, 6 to 150 and 8 to 200.
Layers already split the disciplines — INST-HID and IH- SIMBOLOGIA for the plumbing, ELEC and CABLES DE INSTALACION for the wiring, BAJADAS for downpipes, aspercion for the sprinklers, EQUIPO for plant and FOFO for cast-iron drainage — so freezing a layer hides a whole trade at once. The symbols are legend-scale on a 43 by 36 unit sheet, not real sizes: copy the ones you use into your title-block template, scale them to your text height, and translate the captions once.
