This architectural drawing is Typical details of lintel beams in AutoCAD 2D drawing, dwg file, and CAD file. A beam known as a lintel is typically positioned above windows and doorways. The primary function of the lintel is to sustain the weight of the building above it. Doors and windows cannot be physically designed to support heavy loads on their own. The majority of lintels are found in masonry or brick constructions. For more information and details download the drawing file. Thank you for visiting our website cadbull.com.
