3D Design and Modeling Quiz

What is the primary benefit of making a model in 3D design?

• To reduce the time and cost of production

• To visualize and test how a product looks and performs in 3D

• To replace the need for computer-aided design (CAD)

• To eliminate the use of physical materials

Why can modelling be considered time-consuming and expensive?

• Because it requires special training to view models on a screen

• Because it can only be done using 3D-printable materials

• Because creating physical models allows for hands-on interaction and detailed inspection

• Because physical models are very accurate but also require resources and time to create

Which materials are mentioned as easy-to-form and easily accessible for creating models quickly and cheaply?

• Plastic and metal

• Balsa and cardboard

• Glass and ceramics

• Rubber and leather

When designing a chair, the designer would make scale models and use an ergonome (scaled model of a human) to test it. What is the purpose of this?

• To display the chair in a store

• To test the dimensions to see if a person would fit in the chair

• To model for a photography session

• To test the materials

What is one of the advantages of physical modelling?

• It can be time-consuming and complicated

• 3D printed models can be expensive

• Allows a designer to physically handle a design and view from all sides

• Models can't generally be used for testing

Which of the following is a disadvantage of physical modelling?

• Changes can be made quickly and easily

• Materials such as cardboard can be found cheaply and easily

• Models can be scaled up or down in size

• 3D printed models can be expensive and have limited materials available

Why might physical models not be suitable for testing?

• They allow a designer to view the design from all sides

• They can be scaled up or down in size

• They can be used to show to a client and get feedback before production

• They don’t use the same materials that the product will be made of
