This Architectural Drawing is section of walls. A Wall Section is a technical drawing that lets you see inside a wall. Rarely will a wall be made of just one solid material. Most often what you see on the outside is not all there is on the inside. Typical Wall Details are a handy way to define multiple interior walls in great detail just once and then tag the walls on the plans with the appropriate wall construction tag. For the tag we use a simple short section line connected to a diamond in which the letter designation of the wall type is shown. For more details and information download the drawing file.
