Study Notes
Parametric Modelling
- Parametric modelling is a powerful technique that allows users to easily modify a 3D model by changing its dimensions.
- It is often employed in computer-aided design (CAD) software.
- The software automatically updates the model based on any changes made to the dimensions.
Feature-based Modelling
- Feature-based models are created as a series of distinct features, such as holes, grooves, fillets, and chamfers.
- These features are the building blocks of a 3D model.
Constructive Solid Geometry (CSG)
- CSG is a method of creating complex solid models by combining simpler shapes (primitives) using logical operations like union, intersection, and difference.
- Examples of primitives include cylinders, cones, prisms, rectangles, and spheres.
Boundary Representation (BR)
- Boundary representation is another method for defining 3D solids where the shape is defined by its surface boundaries.
- This method is often used in Finite Element Method (FEM) software because it allows for precise meshing of the model.
Advantages of Parametric Modelling
- Creates flexible and easily customizable designs.
- Offers multiple viewpoints and perspectives of the model.
- Allows for better visualization of the design.
- Streamlines workflows and reduces production time.
- Enables reuse of existing design data.
- Improves design efficiency.
