Lab 3 Multiview, Orthographic, Isometric
IAT106:SpatialThinkingandCommunicating
Spring2017–Lab3
Multiview&OrthographicViews
In this lab you will do a variety of exercises designed to help you further develop your ability to see
and think spatially, and to further develop your sketching skills. There are 4 parts to the lab. This Lab
is worth a total of 100 pts, 10 for the prelab and 90 for the lab assignments.
Pre-LabAssignment
Submit your pre-lab assignment for this week at the beginning of the lab.
PartI
Match Isometric to Multiview: (15 min.)
Your TA will hand this out at the start of the lab. In this exercise, you match a 3-view multi-view
drawing with an isometric drawing. Do any 10 of the 12 parts on your own You will have 10 min to
work on this in the lab, and must hand in the completed exercise at the start of the next lab.
PartII
Identify Multiview to Isometric: (homework)
This exercise will be handed out by the TA. Complete the exercise on your own, and submit to your
TA before the start of your next lab. You are to select an orthogonal view that matches a specified
view of an isometric drawing of an object.

PartIII(60min)
This consists of 3 types of exercise from your textbook. For each type,
1. Your TA will work through the first example on the board.
2. You will work through the next on your own, in the lab. Feel free to ask questions of your TA
and instructor. The answer will be given to you so you can compare with your own result.
3. Complete the “on your own” exercises on your own (you will probably not be able to complete
these in the lab. These are to be submitted at the start of your next lab. One of these will be
marked in detail (the TAs will decide which); the others will be marked complete/incomplete
only. Answers will be posted after the due date so you can check.
Do 2 exercises per sheet of paper, and put your name, student number, date and lab section on the top
right corner of each sheet, printed legibly! You can use plain or grid paper; grid paper may make it
easier and faster to complete the exercises.

PartIV:IsometricDrawings(40min)
Given an isometric view, apply the steps of the boxing-in method described in Section 7.3 of the
textbook to sketch the isometric drawing.
For exercises 1.1, 1.2, and 1.3 below, create an isometric drawing of the object using the boxing-in
method demonstrated earlier in the lab and described in the textbook. Leave construction lines on the
final sketch and make sure that the final form of the object is darkened and visible (sharp and
continuous lines). Please allocate one page for each exercise. Use plain paper, and remember to put
your name, student#, section and date on the top right of EACH page.
Exercise 1.1
Exercise 1.2
Exercise 1.3
Exercise 1.4: (5 min)
For each pictorial, using the provided labels, list the:
• Isometric and non-isometric edges. Use the label “I” or “N”.
•
Isometric and non-isometric surfaces. Use the label “N” and put the label directly on the
drawing.
List only the edges that have a number label at each end. Here is an example.
