N4/5 GC - Geometry (Cylinders)

What is the primary purpose of orthographic projection in technical drawing?

• To create a 3D model

• To represent a 3D object in 2D views

• To add colour to the drawing

• To measure the weight of the object

In technical drawing, what does the term "projection" refer to?

• The method of representing a 3D object on a 2D plane

• The actual size of the object

• The shape of the object when it is flattened out

• The shape of the object in a 3D view

In technical drawing, what does the term "true length" refer to?

• The actual length of an object as seen in a 3D perspective

• The length of an object measured along its true axis

• The length of an object when projected onto a 2D plane

• The length of an object when it is unfolded

Which of the following line types is typically used to represent hidden edges in technical drawings?

• Continuous line

• Dashed line

• Zigzag line

• Chain line

Which organization is responsible for setting technical drawing standards in the UK?

• British Standards Institute

• British Standards Council

• British Standards Organization

What is a "net development" in technical drawing?

• A 3D model of an object

• A 2D layout that can be folded to form a 3D object

• A detailed view of a specific part of an object

• A cross-sectional view of an object

Which of the following views is NOT a standard part of an orthographic projection?

• Front view

• Top view

• Side view

• Perspective view

What is the function of dimensions in technical drawings?

• To add artistic elements

• To specify the size and scale of the object

• To create a blueprint

• To indicate the weight of the object

Which of the following best describes a cylinder in technical drawing?
