Techniques of surface modelling

Remembering: What is the main purpose of surface modeling techniques?

• To generate 3D models of physical objects

• To measure the surface roughness of objects

• To find the volume of objects

• To calculate the weight of objects

Understanding: What is the main difference between surface modeling and solid modeling?

• Surface modeling involves representing a surface with a set of curves, while solid modeling involves representing a solid with a set of surfaces.

• Surface modeling is used for representing mechanical parts, while solid modeling is used for representing architectural structures.

• Surface modeling is used for representing 2D objects, while solid modeling is used for representing 3D objects.

• Surface modeling is used for representing organic shapes, while solid modeling is used for representing geometric shapes.

Applying: What is the most common technique used for surface modeling in computer-aided design (CAD)?

• NURBS modeling

• Polygonal modeling

• Box modeling

• Sculpting

Analyzing: What are the advantages of using NURBS-based surface modeling techniques in CAD?

• NURBS modeling allows for the creation of smooth, curved surfaces.

• NURBS modeling is easy to learn and use.

• NURBS modeling is faster than other surface modeling techniques.

• NURBS modeling can be used to create a wide range of shapes, including both organic and geometric shapes.

Evaluating: What is the main drawback of using sculpting techniques in surface modeling?

• Sculpting can be time-consuming.

• Sculpting is faster than other surface modeling techniques.

• Sculpting is easier to learn than other surface modeling techniques.

• Sculpting can only be used to create organic shapes.
