About Program :
Computational Bridge Information Modelling and Management is a holistic approach for a civil/structural engineer to improve their current skill sets and technique. Digital Transformation in AEC industry worldwide demanding engineer and technician with improved skills , this program is design accordingly.
What is computational/Parametric modelling?
Parametric is a term used to describe a dimension’s ability to change the shape of model geometry as soon as the dimension value is modified.
Feature-based is a term used to describe the various components of a model. For example, a part can consists of various types of features such as holes, grooves, fillets, and chamfers. A ‘feature’ is the basic unit of a parametric solid model.
The Parametric Modelling Process
Parametric models are built from a set of mathematical equations. For parametric models to have any legitimacy, they must be based on real project information. It is the modernity of the information examination techniques and the breadth of the hidden undertaking information which decides the viability of a modelling solution.
There are two popular parametric representation models.
Constructive Solid Geometry (CSG)
CSG defines a model in terms of combining basic (primitive) and generated (using extrusion and sweeping operation) solid shapes. It uses Boolean operations to construct a model. CSG is a combination of 3D solid primates (for example a cylinder, cone, prism, rectangle or sphere) that are then manipulated using simple Boolean operations.
Boundary Representation (BR)
In BR, a solid model is formed by defining the surfaces that form its spatial boundaries (points, edges, etc.) The object is then made by joining these spatial points. Many Finite Element Method (FEM) programs use this method, as it allows the interior meshing of the volume to be more easily controlled.
Advantages
These are the benefits offered by 3D parametric modelling over traditional 2D drawings:
- Capability to produce flexible designs.
- 3D solid models offer a vast range of ways to view the model.
- Better product visualization, as you can begin with simple objects with minimal details.
- Better integration with downstream applications and reduced engineering cycle time
- Existing design data can be reused to create new designs.
- Quick design turnaround, increasing efficiency.
