How to Draw a Section Cut in Plan
Plan Section Pinnacle!!!
In every compages project, you are going to be asked to describe an architectural plan, section and superlative. These drawings are unique to compages and other pattern industries and form the foundation of architectural communication.
Plans, sections and elevations are likely unfamiliar to many new students. These drawings may be explained to you in detail or you may be left to effigy it out yourself. Either way, at that place are a lot of things to call up about to get started and consummate these drawings as a comprehensive and clear method of communicating your blueprint and ideas.
What Is A Plan, Section And Height?
Plans, sections and elevations are all calibration representations as drawings on a folio of much larger, real-life objects or structures. We are shrinking them down.
Learn more in the article titled "How To Use An Architectural Scale Ruler (Metric)."
Plan, section and summit drawings are orthographic drawings.
Orthographicprojection is a mode of representing a three-dimensional form or object in which the object is viewed from a position perpendicular to the cartoon airplane being viewed.

To keep it elementary, let'southward consider a capsicum equally a three-dimensional object that is hollow inside, like a edifice or architectural construction.
A capsicum or a house or a box would normally have a height view, a front end view and a side view, besides as a dorsum view and a second side view. Some of these views may be similar simply unlikely to be the same. The peak view is what is called a plan in architecture. The front, dorsum and side views are called elevations.
When we look at them together, these unlike views give us a full understanding of the total exterior of the object or structure. The only view we are missing is the bottom view.
For a capsicum or a complimentary-continuing object, this lesser view is important and completes our agreement of the object. A firm or an architectural structure has no bottom view as it is fixed to the ground and we do non get underneath to encounter it!!
Architectural Plans
Allow'due south consider plans in a little more detail…
A programme is a view of an object projected horizontally, or from to a higher place. In architectural drawing, this is known every bit a top view, top plan or roof plan.
Our top view of the capsicum is like a roof plan of a building or architectural structure. All the same, this only gives an understanding of the exterior of the three-dimensional form.
Other architectural plans are cut horizontally through the building or object, usually at a acme of about ane,000-i,200mm above the ground or a floor plane. These are normally called flooring plans and requite us information most the thickness of walls and openings too as the qualities, size and shapes of internal spaces.
A flooring program is similar slicing through a capsicum, lifting off the top and so drawing or showing everything you would see – that is both cut through and beneath the level of the cut.
If we look at what exactly has been cut in the capsicum, we can now see the hollow inside space, too as the thickness of the skin, how the peel changes in thickness to create interesting internal shapes and spaces, and the fact the pare is solid and there are no
holes or openings (which we would phone call doors or windows in a building). What is also important is that we can also run into the inside pare of the capsicum behind or lower than the level of the cut.
In a building, nosotros slice through at almost 1,000-one,200mm above the flooring. Let's say nigh ane,100mm. The reason we choose this elevation is that it is about the height where humans use their hands. Information technology is just in a higher place benches and tables, and where most windows volition run through vertically. This means when we cut through at this acme we will capture as much information as possible in our drawings. Consider what you would see if you cut through the plan at 100mm above the floor or 100mm beneath the ceiling. You would miss all the windows, doors and important elements.
If we look through at exactly what is cut through in a building program we run into wall thicknesses, windows, doors and openings . We can see also see what is beneath the line of the cutting such as any built-in furniture similar kitchen benches, sinks, toilets or bathroom vanities. We can as well see floor or ground materials and the meridian of furniture or article of furniture outlines.
If nosotros put the top of the edifice dorsum over again, what we would see is a summit view or roof program.
Architectural Sections
Asectionis an orthographic projection of an object equally if it would appear cut vertically past an intersecting plane.
A section is drawn similar to a floor plan, but vertically. What is most important in a section is the information that is cut through. As a plan, we see wall thicknesses, windows, doors and openings. They must be drawn the same way, every bit in reality, they are the same affair.
As in a plan, nosotros tin can likewise encounter what is behind the line of the section cutting such as whatever congenital-in furniture similar outlines of kitchen benches, sinks, toilets or bathroom vanities also equally wall materials and objects on walls. This information in the distance behind the cut is internal summit information.
In a section, the well-nigh important information is the cut which communicates the material thicknesses, types, openings and the internal and external spaces, forms and shapes created. The internal elevation information is ordinarily indicative or secondary in a section and is shown in more than particular in a drawing dedicated to the internal acme, which nosotros volition get to soon.
If we accept multiple sections cutting through our capsicum or construction, would proper noun each of them with letters – Section A-A, Section B-B etc.
If we put the removed half of the edifice or capsicum back once again, what nosotros would see is an external height.
Architectural Elevations
Anelevation is a vertical view of an object projected onto a pic plane.
A capsicum has a front, back and two side views or elevations depending on how we position ourselves relating to the object. Similarly, a building or architectural structure will normally accept four elevations if it uses square or rectangular geometry. Elevations will be labeled Elevations 1,ii,iii and iv, starting at the top and working clockwise. More commonly they will be labeled Due north, Due south, Due east or W Peak based on the direction the tiptop is facing – not the management you are looking.
A more complex shaped plan with angles or curves may stop of with multiple elevations, but that is beyond what we are discussing here.
It is important to note that a edifice elevation is ever fatigued as if you are standing back away from the construction. The ground plane is e'er cutting through in section because the basis aeroplane is continuous and y'all can never come across it in tiptop.
Internal elevations are usually drawn of private rooms. The begin from inside the line of the section cut to show the internal materials, objects and finishes on a wall or vertical surface.
Drawing A Plan, Department And Elevation
If we were to draw a fix of plans, sections and elevations of the capsicum, nosotros would exist drawing an existing object. As an architect, we might be drawing an existing building or structure. Notwithstanding, more likely we are drawing something that does not be, so are using these drawings as a way to help united states of america design.
When we draw plans, sections and elevations we are cartoon the object or construction in true, real proportions of height, length and width measurements. We must exist very exact and measure everything carefully or our drawings will look distorted. Nosotros must also exist sure that our drawing does non have perspective and is representing flat planes only.
We commonly start our orthographic drawings with a floor program and then we can place our horizontal points in space. Nosotros can so piece of work from the program to project the sections and elevations in the vertical.

Things To Remember…
Hopefully, that gives you a very basic understanding of plan, section and meridian in architecture. In summary, here are a few central things to remember.
- Plans are horizontal views. Sections and elevations are vertical views.
- Plans and sections focus on the "cut." Elevations focus on the vertical planes.
- Elevations are labelled with numbers or compass directions North, Southward, Eastward and Westward based on the management they are facing, not the direction you are looking at them. Sections are labelled with letters.
- Sections and elevations are always drawn with the basis plane cutting through in section.
- Elements cutting in programme and section (ie. wall type and thickness, doors, windows) should be drawn the same style, as they are representing the same thing.
- Internal elevation information is secondary in sections and should generally be indicative.
- Plans, sections and elevations should be accurate, proportional and show the same measurements and points in space throughout each drawing.
