Comprehensive MEP & Architectural AutoCAD Block Library Collection

This extensive library contains 964 standardized AutoCAD blocks organized across 124 layers, primarily focused on plumbing, mechanical, and architectural components. The collection features detailed pipe fittings ranging from DN15 (1/2″) to DN300 (12″) with various configurations including elbows, tees, reducers, and valves. Plumbing fixtures include WCs, urinals, wash basins, and floor drains with proper trap configurations. The library also includes architectural elements such as furniture layouts, windows (single, double fixed, sliding), electrical symbols, and vehicle blocks. Many components include dimensional annotations in both metric (mm) and imperial units, particularly for pipe diameters and fittings. The drawing distinguishes components through a well-structured layer system separating elements by function (walls, furniture, fixtures, electrical). Notable is the comprehensive collection of plumbing Y-tees and reducing fittings with standard angles (45° and 90°) suitable for commercial and residential applications.
