Power Of 3D Surface Modeling: Architectural Drafting And Design

CAD 3D modeling is a powerful tool for The AEC Associates Architectural Drafting and Design services, offering unlimited scope for innovation and experimentation. The modern-day computer software help Architectural drafting and design professionals save time, work efficiently and produce error-free, quality drawings and brilliant, lifelike views. Unlike earlier methods, working with 3D models enables you to think and conceptualize directly in three dimensions, enhancing the quality and accuracy of your designs.

There are primarily three types of 3D models, they are discussed below.

  • 3D Wireframe models

Wireframe modeling is the simplest form of 3D modeling employed for Architectural drafting and design. These models provide just an extended form of 2D orthographic projections. Even though they are far superior to 2D projections, wireframe models still have limitations. You need to edit these models to remove extraneous lines and add hidden and center lines to make them conform to the standards.

  • 3D surface models

A more complex form of 3D models, called a surface model, is used when the exterior surfaces of a structure are more important and you don’t need to consider interior forms yet. This technique represents solid looking objects externally. If we compare three types of models, surface models are more complex than wireframe models but not as sophisticated or complete as 3D solid models. A surface model cannot be sliced open like a solid model; so a proper appearance doesn’t guarantee geometric correctness of a solid looking object.

A surface model only simulates the structure externally, thus it does not give the complete view of the structure. You only use these models for the projects where the exterior holds more importance. You add surface to a wireless model if you need a more comprehensive view at some stage. The limitations of surface modeling include not being able to display internal features of an object, and not being able to prevent a clash of elements, especially in case of complex structures.

  • 3D solid models

Now, a brief description of solid modeling. A 3D solid model is complete in every sense; it gives a life-like view of both exterior and interior surfaces and spaces. It’s possible to obtain a view from any conceivable angle, one can even get an inside out view. These models give you an exact idea of the structure. Despite all its advantages, developing a solid model takes a lot of time and effort, so is used sparingly, employed only when the structure is complex enough and Architectural drafting and design team cannot work efficiently with other forms of 3D models.
