2D design and drafting methods have been replaced by The AEC Associates 3D CAD Drawing Services with 3D computer-aided software in recent years. Structures have been getting more and more complex and construction costs steeper and steeper since skyscrapers became a norm at the turn of the 19th century; architects and other building professionals had to go for the latest technologies to face the challenge. 3D CAD Modeling is a new-age tool that allows 3D CAD drawing services a great flexibility and freedom to play with complex forms and figures and produce breathtaking, yet structurally feasible designs. It has revolutionized the building industry as it’s faster, more accurate, and less error-prone than the previous tools.
Types of 3D CAD modeling
There are primarily three types of CAD 3D models for helping 3D CAD drawing services achieve the level of precision and accuracy with their drawings that is always expected of them. They are-
· 3D Wireframe models;
· 3D surface models;
· 3D solid models;
Following is a brief discussion outlining the advantages of using 3D CAD solid modeling.
3D Solid Modeling:
Being the most comprehensive type of modeling, 3D Solid modeling is always geometrically correct and gives a complete view of the object unlike the other two types. Wireframe models only use lines and angles while surface models represent only the external surfaces of a solid object; these two can be geometrically incorrect. On the other hand, solid models ensure that all surfaces meet properly and there is no possibility of component collision, parts not fitting together or inaccurate quantity calculation. Following are some advantages of using this type of model.
· Accurate simulation of proposed structure
A 3D solid model simulates a structure internally and externally giving a true lifelike representation of the proposed building. This makes it possible for 3D CAD drawing services to review all the aspects of the design before construction begins, and offer a true picture to the clients. You can cut a solid model open and reveal the internal features, thus you can review the internal arrangements and juxtaposition of different facilities even as design is being developed.
· Lifelike views
One may easily get lifelike views of a proposed building from all desired angles, complete with all features and colors. These give you an exact idea of the aesthetic appearance of the proposed structure and may be used for clients or as marketing tools.
· Accurate quantity calculation and schedule generation
These models also enable you to come up with accurate BOM and schedule generation as quantities are represented with exact accuracy; each layer and block is shown as they happen in the design.
