What is the Process of Converting CAD 2D Drawings to 3D Modelling?

The conversion of 2D Drawings to 3D Modelling is a complex process. There are different levels to it. It is easier to create a simple, straightforward object than a whole building. If you are a beginner, it is better to stick to simple objects first. This article will explain how you can convert 2D Drawings to 3D Modelling.

The use of 3D models is common in architecture, healthcare, video gaming, product design, etc.
3D models are preferred as they present a more clear and more realistic view. Architects use them to create magnificent buildings, interior designers use them to create aesthetic homes, and engineers use them to make functional products and infrastructures. These models are used to design, evaluate, and analyze all kinds of objects and buildings. 

What is a 3D Rendering Company?

A 3D Rendering Company is a professional 3D modelling agency. They consist of a team of graphic designers who create interior and exterior 3D models for various clients. SMA Archviz is a 3D modelling company that is quite popular. People want to rely on a company that is experienced and knowledgeable. After all, complex 2D drawings often require the expertise of a professional.

Conversion of 2D Drawings to 3D Modelling 

For converting 2D Drawings to 3D Modelling, there is a need for 3D Rendering Software. You need software to start with.

1) Find the Right Software 

There are many software used for 3D modelling such as Sketchup, Corona, Vray, Blender, 3Ds Max etc. The software you pick depends on:

• Cost plan 
• Your requirements (cloud sharing, material database etc).
• Project requirements (Size of the project, level of complexity etc).
• Your level of experience and expertise

If you are new to this, it's better to select free and beginner-friendly software. Some software may be too expensive and hard to use. So select one that has a user-friendly interface and comes with lots of demos and tutorials 

2) Methods for Converting 2D Drawings to 3D Modelling 

There are four main ways to change 2D Drawings to 3D Modelling. 

Extrusions

It is one of the simplest ways for 3D models. 2D images are supported only by the X and Y axes. All you have to do is add Z-Axis depth to a 2D object. You'll get a 3D object with length, width and depth. It is a good method to create columns, panels and other simple shapes.

Lathing

Lathing is used to create radial objects. Lathing is the method of spinning 2D drawings around its axis. The result of lathing can vary depending upon the axis you are rotating it.

Sweeping

Sweeping, also known as loft is another way to convert 2D Drawings to 3D Modelling. Add polylines and splines to 2D objects. You'll need to create another for polylines and splines. It could be open or closed. If the path has two ends it's called open sweeps. If it is closed, meaning it has only one end, it's called a close sweep. Sweeping is used to create cables, wires, rope, trim etc.

Skinning

Skinning is like creating an open sweep but the difference is that you can use various cross-sectional shapes. After you have selected the shapes, you need to create a path.

3) Add Materials and Textures 

Adding materials and textures to the object is a complicated process. Architectural Drafting Services have lots of pre-created materials stored in their database that their clients can choose from.

Creating materials and textures from scratch can be difficult. You'll need to find a real-world image and equalise, rotate or stretch it. After adjusting it, layers are added to it to give it a realistic 3D look. The fastest way to add textures is by using already created material in your rendering program. Although the choices would be limited, it is a faster and easier way.

4) Lightening  

Have you ever wondered how an Architectural Modelling Company make their models so lifelike? Lightening is a big part of realism. The blend of light and shadows helps to bring your model to life. Add light where you want to highlight and add shadow to create a sense of balance. It may take a few tries to get the perfect blend of light and dark but the final product will look good. 

5) Revision

After you are done with the work, recheck it. Add effects to make it even more real. If there are any imperfections in your model, remove them. Look for any improvements and potential flaws in your design. You can also show them to another person and get feedback from them.

Significance of 3D Models 

Why are people shifting towards 3D models? Following are a few of the common reasons:

• Enhanced visualization
• Better decision making
• Promotes creativity and innovation
• Increases collaboration and communication 
• Better presentation of design 
• Marketing 
• Competitive Edge 

Final Thoughts 

The process and method of changing 2D drawings to 3D modelling takes years of practice. Many professional graphics designers have worked for 10+ years to create perfect renderings. Not to mention that it is time-consuming. 3D modelling requires dedication and consistency. If you find it hard to follow through the instructions, you can always outsource to a 3D Rendering firm. SMA Archviz is an affordable 3D modelling company that can cater to your needs.
