100
This line indicates the visible outlines of an object
What is a visible line
100
These are the three different views needed to create a multiview projection
What are top view, front view, and right-side view
100
This is the unit of measurement when it is not written on the drawing
What are millimeters
100
These are the two different parts used in a diagram
What are nut and screw/bolt
100
These two drafting tools help aid in drawing straight lines with a pencil
What are set squares, t-squares, or rulers
200
This line indicates the placement of an imaginary cut
What is a cutting plane
200
Blueprints are drawn in this type of projection
What is orthographic top view
200
This is the type of scale used for a drawing that is larger than the object
What is a scale increase
200
This type of diagram is a simplified drawing that represents one or more aspects of the functioning of an object
What is a design plan
200
This type of drawing shows all of the different parts or features of the object separately
What is an exploded view drawing
300
This line indicates the centre of a circle
What is the centre line (axial line)
300
This projection is generally not used in any technical drawings as there is too much distortion
What is an oblique projection
300
This is the type of scale used for a drawing that is smaller than the object
What is a scale decrease
300
This element is used in diagrams to show how different parts touch each other
What is colour
300
These lines are often used together when labelling a drawing
What are dimension lines and extension lines
400
This line indicates the surface where an imaginary cut has produced a sectioned view
What is a hatched line (hatching)
400
This projection is used to create a multiview projection
What is an isometric projection
400
This is the size of the object in millimeters if the drawing is 20 with a 1:4 scale
What is 80 mm
400
This diagram reveals the interior of an object, exposing its hidden details to view
What is a cross-section
400
This element of diagram is not required but if present, must follow the same rules or engineering drawings
What are dimensions
500
This line ties a dimension to a particular feature
What is a leader line
500
These are two of the three reasons why we do not use perspective in technical drawings
What is too much work, doesn't show detail, distort angles and dimensions
500
This is the size of the object if the drawing is 30 cm with a 5:1 scale
What is 60 mm
500
This is a simplified diagram that contains information about the construction solutions for manufacturing an object or a system
