Benefits of 3D Modelling in Architecture

What Is 3D Modelling?

3D modelling is a three-dimensional way of creating objects on computers before their final physical form creation. This process has nowadays become important for almost all the items to be created and which we see in the market. It is a very useful and essential technology which makes the creative process easy and quick. There are a number of 3D Modelling software available these days, through which professionals design their objects digitally. This entire process includes working with points, lines and polygons to create shapes and forms in such software.

History of 3D Modelling

Years and years ago, the idea of 3D Modelling came even before computers were invented. The mathematical ideas and calculations that are used for 3D visuals marked the beginning of 3D Modelling, which were as old as the 3rd century BC. Computers were developed in the 1950s for military and scientific use.

CAD or Computer Aided Design systems first came out in the 1960s and when 3D Modelling first came into being and the world came to know about it. But then, it was only the engineers and automation professionals who had access to 3D Modelling software and also had the calculative knowledge to use them. Back then it was expensive and complex for anyone to use them, so it wasn’t easy for people to benefit from them. 

Finally, in the year 1963, Sketchpad, a computer program written by Ivan Sutherland, an American engineer, introduced the world to this software. It is also known as ‘Robot Draftsman’. Sketchpad was made available not only to engineers and other professionals but also to designers and artists from different spheres.

Ivan Sutherland is an American computer scientist who invented the program, Sketchpad, in the 1960s, for which we all are thankful today. He made it easy for all the designers around the globe, be it in any field.

Types Of 3D Modelling

3D Modelling technology in the field of architecture gives access to creators to design digital representations of building and construction in a very precise manner. There are a few 3D Modelling processes according to which one can design his projects. Let’s understand a few of the many ways 3D Modelling can be processed.

  1. Direct Modelling

This type of modelling is mainly used to render photorealistic images where the 3D object created will have simple shapes and forms and the changes in them will not affect the entire project. Max and Blender are the two software which fall under direct modelling. Direct Modelling has two subtypes, polygonal and spline modelling. Let us learn about them too. 

Polygonal Modelling-

A mesh made of polygons is presented on the screen, from where you build different objects by moving and shaping this mesh. This gives the best detailed models and makes the project precise and clear. 

Spline Modelling-

Splines are 2D features which are circles and lines presented on the screen, from where you create complex shapes. You can clearly do a lot with such modelling types except that you cannot add realistic textures to any of the objects but they can be converted into polygon mesh to continue with your creative process. 

2.  Parametric Modelling

Parametric Modelling is a little more complex than direct modelling as it has more mathematical elements to it. One can work on different sets of parameters and create accordingly. But this approach is different from direct modelling as the changes in them will affect the entire design, so one has to be careful while working on it. Rhino, Grasshopper and Autodesk Fusion 360 are the three software which fall under parametric modelling. 

3.  BIM 

BIM stands for Building Information Modelling. BIM is used for construction, designing and planning. It is again a 3D Modelling variant where designers, architects, engineers etc, create projects in 3D representations before building the physical structures. The information gathered in such models can not only be used and stored but also is changeable to improve its design or look. AutoCad, Sketchup and Revit are a few of the many BIM software. 

Why is 3D Modelling Essential?


3D Modelling gives you the most realistic representation of the projects to be built. This is the easiest way to work on any physical model and get to know how things will look like. Any changes to be made can be done quickly and there is a vast variety of being creative with 3D renders. This saves a lot of time for the designers and can take things to the next step only after the client is fully satisfied with the realistic 3D representations.  When things appear realistic, it motivates the person to have a promising thought on what they can see rather than the 2D renders which seem outdated and don’t appeal to the senses. 

Can Be Modified Easily

3D Modelling software comes with a huge scope for changes, modifications, corrections and remodelling. If a person is an expert or a professional, he will easily be able to design models and will also be able to make changes or corrections in such software. They are like blank canvases where designers showcase their aesthetic and creative side by focusing on the client’s taste. If corrections are to be done, it’s not that you will have to pay an extra cost for it, rather it can be done in the project itself and without any added cost. It is a very reasonable and handy technique to create things before starting with their concrete form building. 

Makes Designing Work Smooth and Efficient

As said before, 3D Modelling saves money and time, so it is apparent that it also makes the work progress a lot smoother and more efficient as well. Designers begin working on their projects and become efficient at it, as it increases their progress rate and the escalating output can too be noticed. Designers also work with a combination of 3D, 2D and hand-drawn sketches which can be converted into 3D, making it even better for their work progress and final results. 

Gives A Vision to The Client

As the software are three-dimensional, they present a very realistic picture to the client of how their house or cottage will finally look like. This is a very essential part before the actual building of the house as it convinces the client whether or not to accept the 3D design. Because the designers have a blank canvas to work on, they can create unimaginable designs for their clients but if they are all in 2D or absolutely hand-drawn, they won’t appeal to the client’s eyes. But if the same design is shown in a realistic image, the client will want to keep looking and understanding the design and what they like about it and whatnot. Convincing the client is as important as designing their projects in a 3D render.

Accurate Measurements

Each project is designed according to the measurements in relation to the distance of objects and items placed in rooms all around the house. The total size of the project is calculated and measured based on the measurements and dimensions of each room, bathroom, kitchen, attic, garden, patio etc. If the measurements are absolutely correct, the project is already a success. If in case the measurements go wrong anywhere, they too can be corrected easily without any added cost. 

The entire design team can go through the 3D design and give feedback to the experts after the client has approved it. This way it makes it easier for the entire architectural team to work together for the best outcomes. 

Client Approval

These days 3D Modelling has become the designer’s favourite technology to play with before getting things done in a concrete form. When we talk about architectural or interior designing projects, the experts make sure they make efforts to create the best 3D designs for their clients so that they are convinced and motivated to start with their dream projects. A client’s approval is necessary for things to move forward but before that, the designers and the professionals should create realistic 3D renders in ways where they can provide solutions to the client’s problems as well as keep their taste and needs intact. 

Once the render is ready, the client will want to keep understanding the realistic pictures and show a keen interest in what has been designed. This way they will be compelled and satisfied with the render and will surely approve. Wherever they want any changes or modifications, telling and showing them that too can be done easily, it will motivate them further and finally give the green light. 

Can Be Understood by Anyone

As 3D renders are all realistic visuals, it clearly indicates that they can be understood by anyone. There is no age or language barrier to understand them. Everyone finds images and pictures interesting to look at, and so are realistic images, which are designed carefully by the experts. 

Clients who plan to build their dream home, would show interest to go through the 3D design created, and this includes everyone in the family, be it adults, youngsters, teenagers, kids or even the seniors. Such renders don’t hold measurement and calculation maps but realistic pictures which can be moved, dragged and rotated for a better vision and thus they can be read and comprehended by anyone. 

3D Modelling Impacting Different Industries

Automotive Industry

The automobile industry is yet another industry to have gained a lot from 3D Modelling technology. Designing cars is no less than creating homes for people. Designing cars is a serious job where you know people’s lives can be at stake. Each and every tiny part of the vehicle is designed and created to its best form, which is why 3D representations are necessary for the automobile industry. 

Once the design is created after hours and hours of hard work, calculations, corrections and remodelling, tests after tests are done to check crashes and how they can be prevented. Famous companies like Volkswagen, Mercedes, BMW, Skoda etc, design 3D Models and put them through a lot of testing to finally begin with the physical development of their designs. 

Architecture Industry

Architecture is one industry which has been benefiting the most from 3D Modelling technology. Almost all the building and construction projects created are first done on 3D Modelling software to give the best results to their customers. Creative as the architects are, they use their imagination, knowledge, technicalities and the customer’s dreams to design breath-taking renders which are realistic in nature, leaving the customer awestruck. 

Gone are the days when architects were dependent solely on 2D renders which weren’t that appealing and limited in many ways. 

Manufacturing Industry

Manufacturing industries throughout the world use 3D modelling to design complex parts of different items. Before the actual manufacturing of objects, designers these days take to 3D designing as it makes the entire task easy and less time consuming, also it aids the designers to create things with precision and apt measurements. 

The overall look of the manufacturing objects is first designed in a 3D form which makes it smooth for the creators to go through all the possible modifications to be done for the looks and the functionality of the created object.

Gaming Industry

The ever changing and evolving gaming industry is one huge industry which makes the maximum use of 3D Modelling software as the games created and designed in a 3D representation remain similar to their graphics and use, as there is no physical form to be constructed later on. 

What is designed remains intact for the gamers to play and win. The interface itself is ever-competing in the market offering gamers a better experience with realistic images, landscapes, characters, sounds and overall graphics. Talking about the characters in games today, they are so life-like that a person can think of them more as a real person than animation. Call of Duty, The Witcher and Assassin’s Creed are only a few to count as the best graphics games developed on such software.
