AutoCAD Test # 1

Explain what an orthographic view is and why it is important to engineering graphics.

• A 3D representation of an object; important for visualizing designs.

• A 2D representation of an object; important for accurate measurements.

• A 3D representation of an object; important for artistic purposes.

• A 2D representation of an object; important for aesthetic appeal.

Explain how a miter line can assist us in creating orthographic views.

• By providing a 3D perspective.

• By helping to align different views.

• By adding color to the views.

• By creating shadows in the views.

Describe the two AutoCAD commands that can be used to get geometric information about constructed objects.

• Line and Circle

• Measure and Dimension

• Trim and Extend

• Copy and Paste

Describe when and why you would use the AutoCAD ORTHO option.

• To draw curved lines accurately.

• To draw straight lines horizontally or vertically.

• To add textures to objects.

• To rotate objects precisely.

What is the difference between a line and a polyline in AutoCAD?

• A line is a single segment; a polyline is multiple connected segments.

• A line is curved; a polyline is always straight.

• A line is always horizontal; a polyline is always vertical.

• A line is colored; a polyline is black and white.

Which AutoCAD command can we use to break a compound object, such as a polyline, into its component objects?

• Join

• Explode

• Trim

• Extend

Which AutoCAD command can we use to quickly calculate the area and perimeter of a closed region defined by a polyline?

• Measure

• Area

• Dimension

• Offset

Describe the procedure to calculate the area and perimeter of a closed region defined by a polyline.

• Use the Line command and measure manually.

• Use the Area command and select the polyline.

• Use the Trim command and cut the polyline.

• Use the Offset command and create a new polyline.

What does the Offset command allow us to do?

• Create parallel lines or curves at a specified distance.

• Rotate objects around a point.

• Scale objects to a different size.

• Change the color of objects.

List some of the advantages of using layers.

• Organizes the drawing

• Increases file size

• Makes drawing slower

• Reduces accuracy
