Meaning of Plan and Elevation in Engineering Drawing

Program, Section, and Elevation are different types of drawings used past architects to graphically represent a building design and construction. A programme cartoon is a cartoon on a horizontal airplane showing a view from higher up. An Elevation drawing is fatigued on a vertical plane showing a vertical depiction. A section drawing is also a vertical depiction, but 1 that cuts through space to show what lies inside.

I am Jorge Fontan, an builder in New York and owner of Fontan Architecture. In this post, I volition review some of the basic concepts of architectural drawing.

Plan Drawing Definition

Plan drawings are specific drawings architects apply to illustrate a building or portion of a building. A program is drawn from a horizontal plane looking down from above. This is as if you sliced through a space horizontally and stood over looking down on it. Plans are a common design drawing and technical architectural or technology convention for graphic representation of compages. With the exception of plan perspectives, plan drawings are orthographic projections. This means they are non drawn in perspective and there is no foreshortening.

There are different types of plan drawings:

• Program
• Programme Callout or Blow Up Program
• Program Detail
• Site Plan
• Roof Plan
• Reflected Ceiling Plan or RCP
• Plan Perspective

Program Drawings

A plan drawing shows a view from in a higher place. This is often used to draw the layout of a building, showing locations of rooms and windows, walls, doors, stairs etc. Although plan drawings can exist drawn from to a higher place, they are often drawn cut through the edifice with horizontal plane. The plan is typically cut at a height of about four feet, but the builder drawing the plan may cut it at a unlike summit. This means that you have an imaginary airplane cut through the building at an elevation of 4 feet higher up the floor. Therefore, you run across in the cut annihilation that the plane passes through.

Plan Callouts

Another common architectural convention is the use of program callouts. A callout is an area within the plan that is drawn at a larger scale. For instance, if I take a floor program at i/iv″ = one′-0″ calibration of a firm, I might have a callout of the kitchen and bathrooms, showing them at 1/2″ = 1′-0″ scale. Half inch scale is twice as large as quarter inch scale.

Plan Details

Details in architectural drawings are large scale drawings that typically testify how something is built. Details place all the materials and connections for construction. Details are normally iii/4″ = ane′-0″ or larger. Programme details are drawn in a programme view at a large scale to show the construction.

Site Plan

A site plan may or may not exist fatigued cut through the building. A site plan is going to prove more than only the building, including the entire site the building is located on. This can bear witness the property lines, the building location, utilities, roads, landscape etc. A site plan volition nigh typically be drawn from above the edifice, equally if showing a roof plan of the building within the site program. Sometimes the site plan can exist drawn equally a first floor plan being cut through the start floor. This is done to show the relationship from the exterior of the edifice to the interior archway.

Roof Plan

A Roof Plan is a plan of a building or house that is not cutting through the building just drawn from above. This shows everything on top of the building including the roof layout, stair bulkheads, parapets, and potentially roof equipment.

Reflected Ceiling Plan (RCP)

A Reflected Ceiling Programme is a programme of the ceiling within a space. This is drawn looking down as if at that place is a mirror on the floor reflecting the ceiling. The reflected ceiling plan is often referred to as an RCP. This architectural drawing volition show things light lighting, structure, ceiling heights, soffits, etc…. When I was in my first semester of architecture school the RCP was the hardest drawing for me to understand merely it makes perfect sense once you get it.

Programme Perspectives

A plan perspective is a drawing of a programme but shown in perspective. This is more of a design drawing meant to testify what the space is going to expect like and less how the infinite will exist built.

Elevation Drawing Definition

Elevation drawings are a specific blazon of drawing architects use to illustrate a edifice or portion of a edifice. An Top is drawn from a vertical airplane looking straight on to a building facade or interior surface. This is as if you direct in front of a building and looked straight at it. Elevations are a common design drawing and technical architectural or applied science convention for graphic representation of compages. Summit drawings are orthographic projections. This ways they are not drawn in perspective and in that location is no foreshortening.

In that location are unlike types of Acme Drawings:

• Acme
• Interior Elevation
• Elevation Call Out
• Pinnacle Detail

Department Drawing Definition

Section drawings are a specific type of cartoon architects use to illustrate a building or portion of a building. A section is drawn from a vertical airplane slicing through a building. This is as if you cut through a space vertically and stood directly in front end looking directly at it. Sections are a common design drawing and technical architectural or engineering science convention for graphic representation of compages. Section drawings are orthographic projections (with the exception of section perspectives). This means they are non drawn in perspective and there is no foreshortening.

There are different types of section drawings:

• Section
• Department Callout or Accident Up Section
• Plan Detail
• Site Plan
• Reflected Ceiling Programme or RCP

Every bit an architect, I study drawing closely, but these are complicated and quite involved problems. In this article, nosotros reviewed some of the basic concepts with regards to Plan, Department, Pinnacle Drawings in Architecture. This post does non assume to cover every possible issue or status, merely provide a general overview of the topic.
