There is no one-size-fits-all way for 3D visualization of any kind. There are many ways, spanning different applications, project timelines and budgets.

The following are the main types of 3D modeling you should be familiar with for any architectural modeling project.

Wireframe

If you’re looking for a simple and effective tool to create a quick presentation of a simple design, wireframe is the tool to go with. You might also come across the modeling name edge, but it’s basically the same thing. Wireframe involves outlining a 3D object and filling in the space between the lines or “wires” using polygons.
visualize the project in 3D.

3D CAD modeling

Architects and designers use 3D CAD modeling to create 3D drawings of anything from simple houses to skyscrapers. The fact is that Computer Aided Design (CAD) uses a complex algorithm to turn two-dimensional drawings into three-dimensional structures.

CAD models are mathematically precise, which makes them ideal for visualizing exteriors. So, designers can easily incorporate materials, change colors and add any design elements. Not surprisingly, you’ll find CAD modeling used in a wide variety of exterior rendering services.

BIM modeling

BIM stands for Building Information Models and is the oldest type of 3D modeling. It is also one of the most intelligent and sophisticated types that allow architects, engineers and builders to work together on a single project.

The reason BIM is so popular in architectural modeling is because it allows designers to generate and edit both the physical and functional features of a project.

Also, unlike any other architectural CGI, it allows you to work on the entire building and interior, including spatial relationships, infrastructure, lighting, etc. Consequently, BIM is universal in terms of all phases of planning and construction.

3D interior modeling

To best demonstrate the selling points of design and present the project to investors, designers resort to 3D interior modeling. No technical intricacies. Just making the overall look of the design look great. It includes placing contextual decor, adjusting lights and colors, creating furniture pieces, etc.

CGI exterior modeling

Although exterior design in architectural modeling has the same principle as interior design, just looking great is not enough to attract investors. The image must do more than just look flawless. It has to cover the points of sustainability, optimization and infrastructure.
