3D CAD modeling is a powerful tool for The AEC Associates Architectural drafting services, giving them unprecedented freedom and flexibility to experiment with shapes and forms. The modern day CAD software allows the Architectural CAD drafting services to save time and work more efficiently by improving their workflow. A 3D model is a powerful tool for the designers helping them think and conceptualize directly in three dimensions, and draftsmen to produce accurate 3D drawings and life-like views.
3D CAD Models:
There are basically three types of 3D CAD models in use:
- 3D Wireframe models
- 3D Surface models
- 3D Solid models
We shall discuss the surface models in detail here, explaining the other two types briefly.
The simplest type of 3D CAD modeling is Wireframe modeling. It provides just an extended form of 2D orthographic projections. Wireframe modeling is far superior to the traditional 2D process, but it has its limitations. These models have to be edited in order to remove extraneous lines and add hidden and center lines so that they conform to the standards. This is the most basic type of 3D model and is used to develop the initial design idea.
3D Surface Modeling:
When the interior forms of a structure are not very important and only the exterior surfaces really matter, a form of 3D modeling more complex than the Wireframe modeling is used by the Architectural drafting services, it’s called 3D surface modeling. Surface modeling is a technique of representing solid looking objects. If we compare the three types of 3D models, a surface model is more complex than the wireframe model, but it’s not as sophisticated or complete as a solid model. It’s not possible to slice open a surface model like a solid model. For this reason, a proper appearance is no guarantee that the object will definitely be geometrically correct.
You cannot get the complete view of a structure using a3D surface model since it simulates the structure only externally, and excludes the interior form. Therefore, it is useful only in the projects where the exterior holds more importance and interior form is not to be considered yet. If the designer is using a wireframe model but feels that they need a more comprehensive view, it is possible to obtain a surface model by adding surfaces to the wireframe. 3D surface models have their limitations since they cannot display internal features of an object. It means that there can be a clash of elements, especially in case of complex structures.
3D Solid Modeling:
A 3D solid model is complete in every sense. It’s the most complex of the 3 types of models giving a life-like view of both exterior and interior surfaces. It’s possible to obtain a view from any conceivable angle using this model, even an inside out view is possible that gives you an exact idea of the structure. It allows the user to quickly and easily detect the conflicting elements of the structure, if any. However, developing a solid model takes a lot of time and effort. As a result, these are used only when the structure is complex enough and no other type of model serves the purpose.
Architectural CAD drafting services make extensive use of CAD 3D models today to improve quality and efficiency. With every subsequent version providing some new innovation and added features, CAD software promise to make life even better for the design professionals in future.
