<p>This Architectural Drawing is AutoCAD 2d drawing of 2d ceiling plan cad blocks in AutoCAD, dwg file. Ceilings are not structural elements, but rather <strong>the finished surfaces below a roof or concrete slab</strong>. Many types of ceilings are used in buildings, but the most common are exposed and suspended ceilings. Ceilings provide a space for mechanical, electrical and plumbing (MEP) installations.</p>
