Engineering Drawing and 3D Modeling in CAD Vocabulary Quiz

What is the primary purpose of an isometric drawing in engineering design?

• To show a 2D view of an object from multiple angles

• To represent a 3D object on a 2D plane with equal dimensions along three axes

• To provide a detailed view of the internal components of an object

• To illustrate the assembly process of a product

Which of the following best describes orthographic projection?

• A method of representing a 3D object in two dimensions using multiple views

• A technique for creating a 3D model from a 2D sketch

• A process of simplifying complex designs into basic shapes

• A way to add texture to a 3D model

How does design intent influence the creation of a CAD model?

• It determines the color scheme of the model

• It guides the decisions on how the model should behave and change

• It specifies the material properties of the model

• It dictates the file format for saving the model

What is the role of abstraction in engineering drawing?

• To add unnecessary details to a design

• To simplify complex systems by focusing on essential features

• To create a realistic representation of an object

• To enhance the aesthetic appeal of a drawing

In parametric modeling, what is the significance of parameters?

• They are used to define the color of the model

• They control the dimensions and shape of the model

• They are used to export the model to different formats

• They determine the texture of the model

What does the extrude function do in a CAD program?

• It creates a 2D sketch from a 3D model

• It extends a 2D shape into a 3D object

• It removes material from a 3D model

• It rotates a 2D shape around an axis

What is the purpose of a sketch in CAD software?

• To apply textures to a 3D model

• To create a 2D outline that serves as the basis for 3D features

• To animate a 3D model

• To simulate the physical properties of a model

How does a chamfer differ from a fillet in CAD design?

• A chamfer creates a rounded edge, while a fillet creates a flat edge

• A chamfer creates a flat edge, while a fillet creates a rounded edge

• Both chamfer and fillet create rounded edges

• Both chamfer and fillet create flat edges

What is the function of the fillet tool in CAD software?

• To create a flat surface between two edges

• To create a rounded transition between two surfaces

• To cut a hole through a 3D object

• To mirror a 3D object

What does the revolve feature do in a CAD program?

• It creates a 3D object by rotating a 2D profile around an axis

• It mirrors a 3D object across a plane

• It scales a 3D object to a different size

• It translates a 3D object along a path
