Parametric three-dimensional (3D) modeling of buildings offers numerous benefits over computer-aided drafting (CAD drafting) for structural engineers. Buildings are compound products involving relatively large numbers of individual parts that are assembled in multiple sections for different design, analysis and construction purposes.
Modeling buildings in fully parametric 3D computer-aided design (CAD) software offers numerous advantages in terms of productivity, flexibility to modify design at different levels and significant reduction in errors that result in cost reduction. However, full realization of these benefits requires technical skills, comprehensive modeling, objects with functional behavior, integration of structural design intent, automation of layout and detailing.
At present, 3D parametric modeling for design analysis is common, but structural design is still mostly communicated using drawings. Since construction projects differ significantly in their physical composition or in the development of their design make it difficult to compare projects built with and without 3D modeling.
3D modeling is widely accepted technology for design of building structures, making the process of engineering design and detailing more effective and productive as compared to 2D CAD systems. With 3D modeling, sets of design documents can be prepared by different design teams with differing levels of information and can be collaborated on single platform.
In a sense, 3D building modeling systems (such as AutoCAD and Tekla) are viewed as collections of predefined functional objects, with embedded analytical functions, that include a comprehensive library of the common structural objects. 3D CAD modelers can define new physical objects as per the requirement of design using the functionality of existing functional objects. This feature helps in east adaptation of modern design with fewer hassles.
Last decade has witnessed a significant growth in use of 3D modeling in the Architectural and Structural fields. Many 3D modeling firms in India and Asia can aid to your project with their skilled modelers and CAD techniques - all of it with great offshore economies.
