What is Plan Section and Elevation?

Plan section elevation of a building are actually three distinct types of drawings that architects and designers use to visually represent a design or construction. The plan gives a bird’s eye view of a space while section drawings provide more structural details. Elevation drawings are, however, made to show a particular portion of a building. I heard about these terms for the first time when we remodeled our home. Everything had to be redesigned and a new layout was made by our interior designer.

So, these drawings provide tiny details that can help create a visual and thus give an accurate representation of a space.

You will be required to create an architectural plan, section, and elevation for every architecture assignment. The basis of architectural language is formed by these drawings, which are specific to architecture and other design sectors. So let’s understand what is plan section elevation of a building.

Plan section elevation examples:

1) Plan: A plan is a representation of an object that is horizontally or above displayed. This is referred to as a top view, top plan, or roof plan in architectural drawings. Other architectural plans are sliced through the structure horizontally, typically between 1100 and 1300 millimetres above the ground or a floor plane. These are commonly referred to as floor plans and provide details on the characteristics, dimensions, and layouts of internal areas in addition to the thickness of walls and openings.

2) Section: A section is a projection of an element made to look as though a plane were meeting it vertically. Equivalent to a floor plan, but shown vertically, is a section. The data that is cut through is what matters most in a section. We can see the sizes of the walls, the windows, the doors, and the openings. Since they are the same thing in reality, they must be represented similarly.

3) Elevation: A vertical image of an element that is portrayed on a picture plane is called an elevation. It is necessary to keep in mind that a building elevation is always represented from a distance away from the building. Because the ground plane is constant and never visible from elevation, it is always sliced through in sections. Now you know what is plan section and elevation.

Important points about the plan and section elevation of a building:

• Plans and sections highlight cutting. Elevations concentrate on the vertices.

• Elevations are marked with numbers or geographical directions depending on the direction they are heading, not the direction you are viewing. 

• This is different from the way you are looking at them. Letters are used to identify the sections.

• The ground plane is usually cut through in sections and elevations when drawing them.

• Plan and sectional elements, such as the kind and thickness of walls, doors, and windows, must be represented in the same way because they represent the same item.

Now you are aware of what is a plan section elevation of a building.
