I would like to spend a few minutes explaining to you the difference between a floorplan a building elevation a building section wall sections and details typically a floor plan is a slice that's happening through a building and the slice is normally measured about four feet six inches above the finished floor or the ground plane of a building so a floor plan is a horizontal slice through a building an elevation is a slice that is outside of the building that looks straight on at the different sides of a building so we have floor plans that are horizontal slices through the building elevations that are vertical slices at the outside of the building a building section is a vertical slice that happens through a building the floor plan the building elevations and the building sections are normally shown at the same scale throughout a set of drawings where the floor plans the elevations and the building sections are relating information at the same level of detail we also have something that is called a wall section in a wall section we are zooming in closer on some specific information so that we can show even more detail last but not least we have a detail itself with the detail we are really zooming in on information provided within the set of construction documents so we have a floor plan which is a horizontal slice through the building we have elevations which are slices out side of the building looking at the building we have building sections which are slices through the building we have wall sections which are enlarged areas within the drawing and we have details which are providing yet more information on the drawing these are the typical kinds of information that we show throughout a set of construction documents
