Basic Lines & Geometric Lines in Technical Drafting
True or False: Two types of basic lines have arrows at both ends
True
What am I? I am a two-dimensional representation of the different views of an object.
Multiview projection
What am I? It specifies all the details needed to make a part of an object
Detail drawing
Design plan or technical diagram?
What diagram shows the guide and linking components in an object?
Technical diagram
What am I? I am a line with an appearance and a meaning that are determined by international conventions
Basic line
What basic line indicates the length of an object or part of an object?
Dimension line
What am I? I am a perspective drawing in which the angles formed by the main edges, representing the length, width and height of the object, equal all 120 degrees.
Isometric projection
What am I? An isometric projection is often used to make this type of drawing
True or False?
Ideally, the names of parts should not be indicated in a design plan.
False
What am I? I am a representation of the inside of an object, providing a clearer view of certain details.
Cross-section
What drafting instrument is illustrated and what basic line is number 4?
T-square and hidden line

Design plan or technical diagram?
David wants to illustrate the motion of parts in a power drill.
Design plan
What am I? I am a type of drawing that represents the parts of an object as exactly as possible
