What is a Technical Drawing?

Just put, a technical drawing is a drawing that conveys data or education to the intended viewer.

Technical drawings are bluish print style drawings that brandish a products information, from dimensions like elevation, width and depth, to specified information such equally materials or associates details.

Technical drawings are used widely throughout many industries by professionals including architects, engineers, CAD Technicians, product designers, and mathematicians. Some of these professions tin exist broken down into various professions that all engage in technical drawing.

Below is a list of the various types of technical cartoon and their uses. Now because this is a website near architecture, the list of technical drawings that nosotros will go through are only architectural. We will only exist going through the list of compages focused technical drawings.

Architectural Technical Drawing

Below is a list of the various types of technical drawing and their uses. Now because this is a website virtually architecture, the list of technical drawings that we will become through are only architectural. Nosotros volition only be going through the list of compages focused technical drawings.

In the architecture world, architects and architectural technologists/technicians produce drawings for building design. These architectural specialists specialise in both rough sketching for presentation and technical cartoon for assembly pedagogy, material specifications, dimensioning.

The manufacturers or constructions workers use the architectural technical drawings to put together building components, or to construct a build according to what the drawings have specified. Below is an explanation of diverse drawings produced by architectural specialists.

Flooring Plans

A floor plan is like a map of the building and it shows the reader how the building is laid out, you can use the flooring program to run across the positions of building components such as walls, windows, doors, room sizes , and loose components similar furniture.

A fixed component is called a dead load and a loose component like a chair or table is called a live load. People who use and movement throughout the building are also considered alive loads.

All the technical drawings of a edifice can exist used in conjunction with one another, a floor plan can be used to see the 'x' and 'y' direction positions of the building components and a costless or co-operative elevation cartoon can be used to run into the 'z' axis direction of the same components.

Because the '10' and 'y' centrality beingness the limited nature of the floor program, the floor plan only shows one level of a building at time. And so in that location is a split up plan drawing for each floor including roof level and foundation level.

Dimensions

Measurements on a flooring programme are represented by dimension lines, in that location are dissimilar styles of dimension lines but all serve the same office; to mark out the distances in the rooms and the exact numerical positions of the doors and windows, and as well the wall widths and sizes.

Floor plans brandish a number of symbols which all show a pregnant for the symbols. Gridlines for example are used to assistance keep a building lined up. Grid lines can also be used to mark out column positions and walls to the gridlines.

Annotations and Symbols

Floor plans brandish a number of symbols which all show a meaning for the symbols. Gridlines for case are used to help proceed a building lined upwards. Filigree lines can besides be used to marking out column positions and walls to the gridlines.

Another information displayed on a flooring plan is textual information. This is a body of text that might have an arrow symbol pointing to a component and the text would explicate the backdrop of the components, for example, a wall specification.

So the text would describe what the wall comprises of past listing each of the materials and their dimensions. For example, a cavity wall comprised of 102.5mm brick, 75mm cavity role filled with Rockwool insulation, 100mm of 7kn cake piece of work.

Text information can also betoken the viewer out to check specified particular drawings about the building component. The text data mentioning the cavity wall tin mention something like 'See wall item one', and the viewer tin can become to check the relevant item canvas to understand the makeup and build of the wall further.

References for Scheduling

The floor plan too displays references for the components in the building, this is especially useful When in that location are number of the same components used, for example the internal doors of a house. The door for a bathroom might be different to a door for a bedchamber. The external door is definitely different to the internal doors, but information technology may likely be dissimilar to the back door leading to the garden for case.

Beneath is a schedule of doors/windows showing how this can be laid out in a table format. Each of the windows have references which are used on the floor plan to locate the components. Plans are typically fatigued at a 1:50 calibration.

Another case of a symbol on the floor program working in conjunction with other drawings is the section view symbol, this marks out a section of the building that we can view equally if nosotros have cutting into a slice of cake and are seeing the internal layers of the cake, or the internal cut view of the building.

An top view tin can be used in a similar way, the elevation view is kind of like an arrow that points to a part of the edifice, and it would reference to an acme view of where the arrow is pointing, the usual places to discover elevation symbols are the top, bottom and sides of the floor programme, which will prove the North, East, South and West sides of the edifice and reference them as such.

The rooms of a floor plan tin be marked out to show their uses and the squared area, and to further break it down, or zoom in; a dedicated room programme tin can exist drawn to bear witness only the specific units of the room in more than detail.

The plan beneath shows the room layout detail of an art room class at a school. the room plan is accompanied by gratuitous cut sections of the room. The textual information details each and every live load component of the room, as well as the structural dead load.

You might notice faint lines on a floor plan that look like they item another room. The faint lines are to indicate the layout of the floor or room to a higher place or below. The purpose of these plans are to give us insight into the edifice which we otherwise could not have by our ain man faculties.

Floorplan Detailing Video

Below is a video showing yous how a floor program is detailed so that it tin exist followed by builders to gather the building or set out the walls, door and windows. In the video I get through vii details to include on a floor plan drawing and they are:

Furniture
Dimensions
Structural opening indications
Component labels
Room names
Symbols (like a low-cal switch)
Textual and descriptive annotations

What is a drawing canvass?

Before we motility on to the other types of technical drawing, first lets explain what a drawing canvass is. A cartoon canvas will take the primary torso of the cartoon on the majority view of the sheet, this can be a drawing like a floor programme, a section view, a roof plan then on.

The corner of the sail houses (no pun intended…okay perhaps it was) a box grid that displays the property information of the drawing. It volition show the title of the drawing, the technician that produced the drawing (whose name is abbreviated into initials), the checker who checked the cartoon for whatever discrepancies, the projects number, client name, date, drawing sheet reference and the scale of the cartoon.

All of the information is used to organise the drawing sheets so that they can be compiled into a set of documents to exist used for construction, building approval or handover to the client. Sheets are compilations of the types of technical drawing.

Below is a list of the different types of technical drawings and the explanations for each of them. The majority of the purpose of a technical drawing has been explained already, and then nosotros will merely get through what the other types of technical drawing are and how they are used.

They all comprise like information to a floor programme, they just bear witness the views of the building that cannot be seen in a floor plan.

Height drawings

This explained briefly before is a view of a side of a building. The typical views of the sides of the building are oriented as North, South, East and West. Height drawings can be used to wait within of a building, but that would be stepping into cross section territory.

An elevation is used to testify how a edifice is supposed to look from the outside, below is an height drawing I did for someone in USA, Georgia. You lot will notice that this drawing has no defining information on information technology.

The drawing was produced by using photographs of a newly built home and the client requested to leave the measurement and material information out. If I were to include the defining information, I would take added a meridian and width dimension to the edifice, and I would have dimensioned the positions of the doors and windows.

Also I would have added an bending dimension to the pitch roof. Pretty much as explained before, I would have as well added textual information on the sides to display specific data such every bit the materials used on the outside face of the building, and the materials used to back up the outside confront of the building.

Elevation drawings are also used to interest the client and show them how the edifice will look in the stop, even though clients tend to alter things frequently and information technology's not unusual to cease upwardly with a edifice that is unlike from what was planned and discussed earlier with the customer, but that's another conversation.

The meridian drawing used for the client may tend to exist more of a sketched elevation rather than a technical elevation. 1 of my architectural lecturers taught me that we produce 2 kinds of works for a project; ane is a compilation of sketch like drawings for the client to see, and the other a to scale technical version for manufacturers to produce.

An architectural drawing takes sketch proposals and makes them workable in real life. This is 1 of my favourite types of technical drawing to produce.

Cross/Longitudinal Sections

Like an peak drawing, the cantankerous section of a edifice is a sort of 'side view' of the building, only it views a dissection of the model to show how it looks from the inside. A cross section is used to see the support structure hidden within the fabric of the building and other subconscious elements that might not exist visible on the floor programme.

In the fine art room layout sheet, y'all can run into supporting drawings that testify a cut view of the room. This view reveals the layers of the external cavity wall and the internal cake wall coated in plaster.

The cross section is marked out on floor plan equally a line with a reference. In CAD softwares such as Revit, the section lines are given a symbol which can contain references in them to the relevant department view. A hand drawn gear up of plans would simply contain a written reference labelled equally 'A101, A102, A103…' for example.

Where the cross section cuts through the outside of the building, that border cut line is represented with a thick line. Whatsoever parts that are revealed as a effect of the section but not cut through, are represented by thinner lines.

Detail Drawings

A particular drawing is a '2D zoom in view' of a small section of a building which highly details certain fixing aspects of the building (trying not to utilise the discussion 'detail' to explain details). In other words it'due south a highlighted focus of a fixing detail or section of a building.

And then allow'due south go right into an instance of a detail drawing. The video beneath shows a hand fatigued cavity wall detail drawing where each part of the wall and its support is detailed for clarity. Some types of technical drawing I produce are by hand and item drawings are one of the ones I savor making videos of,

(Draw Technic is now Technical Draft, just so yous know).

You can see that the particular is deeply focused on the of the building component in question. With the basis floor crenel wall, it shows with dimensions the layers of the wall, including how its supported past the foundations, and how the floor that adjoins the wall on the inside is supported by layers of substructure.

Each separate layer of substructure is specified by the detail, and a drawing similar this can make information technology clear to site workers on how to put together this part of the building. You can commencement to see how builders can use all the different types of technical drawings in conjunction with i another to understand the edifice as a whole and build it slice past slice.

Details tin can all be seen in a cantankerous section view, only the cantankerous department view is purposed to testify a cut through of the building. This cut through can be used as sort of primary detailing legend. Each area on the cantankerous section requiring a detail to farther explain how it'south put together is highlighted past a dashed line box.

The dashed line box is given a reference, and the reference is to the relevant item cartoon that focuses in on the pocket-sized department . This dashed line box on the section view is called a 'callout' (Proverb 'details' to explain details and calling out 'callouts' as 'callouts'), and a number of callouts can be marked on a section view.

On a basic house, you would probably find 10 details to highlight with detail drawings. The details would be placed on a separate sheet, 4 or 5 on a sheet. Each detail is titled with the callout reference given in the section view.

3D Details

The sub heading is self explanatory. This is a detail drawing that is displayed in 3D. A 3D drawing is useful to give clarity to a 2nd drawing or whatsoever part of the building. When ii or more views of the same particular is required to be shown, a 3D item is more suitable for the part.

Since we accept used a crenel wall detail for the 2D detail, I will utilize the cavity wall particular once more for the 3D detail below. This is so yous tin compare the ii and see how the 3D particular shows you lot more clearly on how not only the cavity wall is supported by the foundation, but how the foundations besides back up the flooring joists that hold upward the floor.

During the early days of my time at an compages school; when I learned about house construction, I plant it difficult to empathise 2D details for the first fourth dimension, I couldn't mentally project a 3D view of the 2d detail because I didn't know the depth of each component and how they fit in the detail.

Run into that's what I was looking for. I needed to come across the right types of technical drawing. I needed to run into 3D details so that I could empathize what the second particular is communicating to us. In the 3D detail, you can encounter how the joists are laid out and spaced autonomously, which is something you couldn't see in 2d.

Depending on the management that the joists were spanning, you would either see the cavity wall with the joist, or the spaced out joists against one side of the wall. The 3D view gives you a comprehensive motion-picture show and a better understanding of how it all fits together.

Beneath is a video of a hand drawn 3D window particular sketch that shows a cut through section of the window to see how it works on the inside.

Roof Plans

A roof plan is like a floor programme, but you lot guessed information technology; it shows the structural framing of the roof. A small building'due south floors and walls tin can be built without structural framing, but a roof is always a structural frame of some sort.

The function of a roof is to cover a walled space, and then information technology'southward structure is a network beams or trusses (which is a set of connected beams or members) connected to back up itself – information technology is suspended in the air with its edges resting on the walls. Information technology transfers loads down through the walls.

If y'all would like to acquire more nigh how building forces affect buildings and how building designs deal with the forces, then bank check out this article about four of the building forces that human action on structures (Link to 'Forces Acting On Building Structures' article post).

This network of connected beams is shown on a roof programme, and like a flooring program, information technology is dimensioned and filled with descriptive texts to define the backdrop of the roof frame. The plan shows how information technology is continued, how it connects to the building and what materials are used on it.

At that place would be specifications for materials such equally roof tiles, insulation, weatherproofing and more than. Also whatsoever information most openings in the roof where a specified roof low-cal/window opening might be required.

Site Plans

A site program is a type of drawing that shows a top down view of the site with the proposed edifice placed in position, showing it's interaction with the environment.

This forms a role of the site assay shows the infrastructure in the country of the building and it shows the relationship of the building with the surrounding surface area. It is commercially favourable for a building to be consider and work with the infrastructure around the building.

Choosing a site is incredibly important in the architectural blueprint procedure because it is the major influence in the success or failure of a project. I have written lengthy articles which become in depth into choosing a site and performing a site investigation to see if the land volition exist skilful to build on.

The second article talk about site preparation for building construction once the results from the site investigation are uncovered. And so the 3rd article goes further into what kind of foundations can be set in various kinds of site.

You can notice those manufactures by post-obit these links below:

Link to 'The Architectural Design Procedure Pt.1 – Choosing the Site'.

Link to 'The Architectural Blueprint Process Pt.1.ii – Site Preparation'.

Link to 'The Architectural Design Process Pt.2 – Building Foundations'.

The drawing of a site plan tends to exist used for client presentations. That ways the use of creative graphic representation and colours. At that place is besides a technical set of drawings which bear witness builders or contractors the placements of drainage around the site, the landscaping of the area and any existing structures that may bear on the site piece of work.

Site plans can be designed by architects and engineers, but tin can besides be prepared past surveyors, who specialise in surveying the landscape for site investigations.

Conclusion

So these are the various types of technical drawings produced every bit part of an architectural project and used past builders to put together the very building you're sitting in and reading this from.

Currently I am working on making videos going through and explaining each one as I demonstrate how to produce them. The videos volition be available at the 'Drawing Technical' YouTube aqueduct, withal, they will make it on to this website once set.
