There are primarily three types of CAD 3D models:
· 3D Wireframe models;
· 3D surface models;
· 3D solid models.
We will focus here on the advantages of using 3D CAD solid modeling.
3D Solid models are the most comprehensive type of models, always geometrically correct and giving a complete view of the object unlike the other two types. While wireframe models only use lines and angles,and surface models represent only the external surfaces of a solid object;these two can be geometrically incorrect.Solid models,however, ensure that all surfaces meet properly and there is no possibility of component collision, parts not fitting together or inaccurate quantity calculation.Let us discuss some main advantages of using CAD 3D modeling.
· Accurate simulation of a structure
A 3D solid model gives a true, lifelike representation of the proposed structure by simulating it internally and externally.Architectural drafting and design team is thus able to review all the aspects of the design before actual construction begins, and present a true picture to the clients. It’s possible to cut a solid model open and reveal the internal features, the internal arrangements and juxtaposition of different facilities can be reviewed conveniently even as design is being developed.
· Obtaining true, lifelike views
You can obtain true, lifelike views of a proposed building from just any conceivable angle, complete with all features and colors from a 3D solid model.The user thus gets an exact idea of the aesthetic appearance of the proposed structure.This feature is often used for conveying the idea of the building to the clients or as marketing tool.
· Quantity calculation and schedule generation
These models also enable Architectural drafting and design professionals to prepare accurate Bills of materials and time schedules as quantities are represented with exact accuracy; each layer and block is shown as they happen in the design.
3D CAD modeling is a great tool for Architectural drafting and design team to deal with complex and complicated structures in an era where construction costs have skyrocketed. These models give a true picture of the proposed structure and are especially useful while designing multi-layered buildings.
