Technical Drafting Tools

What is the purpose of a T-square in technical drafting?

• To add color to the drawing

• To measure angles accurately

• To draw straight lines and ensure perpendicularity with the drawing board edge.

• To create 3D models

Explain the difference between a compass and a divider in technical drawing.

• In technical drawing, a compass is used to draw circles and arcs, while a divider is used to transfer measurements and divide lines accurately.

• A compass is used for measuring angles, while a divider is used for drawing straight lines.

• A compass is used for shading, while a divider is used for coloring.

• A compass is used for marking points, while a divider is used for erasing mistakes.

What are the common technical drawing standards used globally?

• BS 8888 and JIS B 0031

• ISO 128 and ASME Y14.5

• ANSI B4.1 and DIN 406

• ASME Y14.6 and ISO 8015

Describe the concept of isometric drawing and its importance in technical drafting.

• Isometric drawing is a method of visually representing three-dimensional objects in two dimensions. It shows the object from a specific angle to give a 3D view. Isometric drawings are important in technical drafting as they provide a clear and accurate representation of the object's dimensions and features, aiding in the design and communication of complex structures or products.

• Isometric drawing is only used for artistic purposes and not in technical drafting.

• Isometric drawing is a method of visually representing two-dimensional objects in three dimensions.

• Isometric drawing does not accurately represent the dimensions of an object.

How is orthographic projection related to dimensioning techniques in technical drawing?

• Orthographic projection is used for coloring in technical drawing

• Dimensioning techniques involve creating 3D models in technical drawing

• Orthographic projection is only used for artistic purposes in technical drawing

• Orthographic projection is the method used to create the views where dimensioning techniques are applied to add measurements and annotations.

What is the significance of using different line weights in technical drafting?

• Using different line weights makes the drawing look messy and unprofessional

• Line weights help in distinguishing various components, highlighting important details, and organizing the information effectively.

• Line weights have no impact on technical drafting

• Line weights are only used for aesthetic purposes in technical drafting

Name three essential drawing instruments used in technical drafting.

• protractor

• pencil, ruler, compass

• pen

• highlighter

What is the role of a protractor in technical drawing?

• To create 3D shapes

• To measure and draw straight lines

• To measure and draw angles accurately.

• To calculate area and perimeter

Explain the term 'scale' as used in technical drafting.

• The term 'scale' in technical drafting refers to the ratio between a measurement on a drawing or model and the corresponding measurement in real life.

• Scale is the process of resizing a document in technical drafting.

• Scale refers to the color scheme used in technical drafting.

• Scale is the tool used to measure angles in technical drafting.

How does the use of CAD software impact traditional technical drawing methods?

• CAD software simplifies and enhances traditional technical drawing methods.

• CAD software has no impact on traditional technical drawing methods.

• CAD software complicates traditional technical drawing methods.

• CAD software makes traditional technical drawing methods obsolete.
