This set of Engineering Drawing Multiple Choice Questions & Answers (MCQs) focuses on “Isometric Drawings”.
1. If isometric projection of an object is drawn with true lengths the shape would be same and size is how much larger than actual isometric projection?
a) 25%
b) 29.5%
c) 22.5%
d) 33.3%
View Answer
Explanation: If the foreshortening of the isometric lines in an isometric projection is disregarded and instead, the true lengths are marked, the view obtained will be exactly of the same shape but larger in proportion than that obtained by the use of the isometric scale.
2. If an isometric projection is drawn with true measurements but not with isometric scale then the drawings are called ____________
a) Isometric projection
b) Isometric view
c) Isometric perception
d) Orthographic view
View Answer
Explanation: Due to the ease of construction and the advantage of measuring the dimensions directly from the drawing, it has become a general practice to use the true scale instead of the isometric scale.
3. If an isometric drawing is made use of isometric scale then the drawings are called ___________
a) Isometric projection
b) Isometric view
c) Isometric perception
d) Orthographic view
View Answer
Explanation: To avoid confusion, the view drawn with the true scale is called isometric drawing or isometric view, while that drawn with the use of isometric scale is called isometric projection.
4. Identify the front view of the below isometric view.
a)
b)
c)
d)
View Answer
Explanation: Here the isometric view of some example picture is given. Arrow in question represents the line of sight in case of front view from that we can get other views. Front view is asked which can be watched along the arrow.
5. Identify the top view of below isometric view.
a)
b) 
c) 
d)
View Answer
Explanation: Here the isometric view of some example picture is given. Arrow in question represents the line of sight in case of front view from that we can get other views. Top view is asked so considering the arrow we can find top view.
6. Identify the side view of the below isometric view.
a)
b) 
c) 
d)
Explanation: Here the isometric view of some example picture is given. Arrow in question represents the line of sight in case of front view from that we can get other views. Side is watched from left side or right side of arrow placed.
7. Identify the side view of the below isometric view.
a) 
b) 
c) 
d) 
View Answer
Explanation: Here the isometric view of some example picture is given. Arrow in question represents the line of sight in case of front view from that we can get other view. Side is watched from left side or right side of arrow placed.
