What is one advantage of computer-aided design (CAD) programmes?

• Low quality drawings

• High quality drawings can be produced

• Drawings cannot be magnified

• Objects cannot be viewed from any angle

Answer explanation

One advantage of CAD programs is that they enable the production of high quality drawings, allowing for precision and detail that manual methods may not achieve.

Fill in the blank: Drawings can easily be ________ using computer-aided design (CAD) programmes.

• magnified

• rotated

• printed

• saved

Answer explanation

Drawings can easily be magnified using CAD programs, allowing users to view details at different scales. While they can also be rotated, printed, and saved, the most relevant action in this context is magnification.

Which of the following is a benefit of using CAD programmes?

• A) Standard details cannot be saved

• B) Drawing layers cannot be produced

• C) Standard details can be saved and reproduced

• D) Objects cannot be viewed from any angle

Answer explanation

The correct choice is C) Standard details can be saved and reproduced. CAD programs allow users to save templates and details, making it easy to reuse designs, which enhances efficiency and consistency in drafting.

Fill in the blank: Drawing layers can be produced enabling particular ________ to be extracted.

• details

• colours

• shapes

• textures

Answer explanation

The correct choice is 'details' because drawing layers are often used to isolate and extract specific details from a larger image or design, allowing for focused analysis or modification.

What is an advantage of CAD programmes regarding object viewing?

• A) Objects can only be viewed from one angle

• B) Objects can be viewed from any angle

• C) Objects cannot be viewed

• D) Objects can be viewed from two angles only

Answer explanation

CAD programs allow users to view objects from any angle, providing flexibility and a comprehensive understanding of the design. This capability is essential for detailed analysis and presentation, making option B the correct choice.

Fill in the blank: Drawings can be ________ without taking up space using CAD programmes.

• archived

• deleted

• printed

• shared

Answer explanation

The correct choice is 'archived' because CAD programs allow users to save drawings digitally, thus they can be archived without occupying physical space. Other options like 'printed' or 'shared' imply taking up space.

What is a feature of CAD programmes related to file sharing?

• Drawings cannot be sent via email

• Drawings can be attached as files and sent via email

• Drawings can only be printed

• Drawings cannot be shared

Answer explanation

CAD programs allow users to attach drawings as files and send them via email, facilitating easy sharing and collaboration. This feature enhances communication among team members and clients.

Fill in the blank: Three dimensional models and ________ can be created using CAD programmes.

• walkthroughs

• animations

• blueprints

• simulations

Answer explanation

Three dimensional models and walkthroughs can be created using CAD programs. Walkthroughs allow users to virtually navigate through a model, enhancing visualization and understanding of the design.

What is a compatibility advantage of CAD programmes?

• CAD cannot be used with other software

• CAD can be used with other compatible software products

• CAD is only for drawing

• CAD cannot prepare schedules

Answer explanation

The correct choice highlights that CAD programs can integrate with other compatible software, enhancing their functionality and allowing for better collaboration and efficiency in design processes.

What are the disadvantages of computer-aided design (CAD) programmes compared to traditional drawing methods?

• CAD programmes are more expensive and require training.

• CAD programmes are faster and more efficient.

• CAD programmes offer more precision and flexibility.

• CAD programmes are universally compatible with all file types.

Answer explanation

CAD programs can be more expensive due to software costs and require training to use effectively, which can be a barrier compared to traditional drawing methods that may not have these requirements.
