SUMMARY

The discussion revolves around interpreting orthographic projections, specifically deducing the side view of an object from its top and front views. Participants emphasize the importance of stereometric insight, which varies among individuals. To enhance understanding, it is recommended to study textbooks and search for resources on "orthographic projection." The conversation also clarifies that the first view is assumed to be the top view and the second as the front view, based on the question's wording.

PREREQUISITES
  • Stereometric insight
  • Understanding of orthographic projection
  • Ability to interpret multiple views of an object
  • Familiarity with technical drawing conventions
NEXT STEPS
  • Study textbooks on orthographic projection techniques
  • Research online presentations about stereometric visualization
  • Practice drawing third views from given top and front views
  • Explore software tools for 3D modeling and projection analysis
USEFUL FOR

Students preparing for exams in technical drawing, architects, engineers, and anyone seeking to improve their skills in interpreting orthographic projections.

Hi, I have this mcq . The image shows the Top and Front view of an object, what is the side view of this object? I am finding it very difficult to even interpret the top and front views. I will get questions like these in my exam so I must be able deduce the 3rd view from 2 given views of the object.

Hello Tip,
:welcome: ##\qquad## !​

This comes down to stereometric insight, which, for some, is a breeze, and -- for others -- is a nightmare.
One way to build experience is to study your textbook; another is to google 'orthographic projection' and view some presentations.

Have you already determined which of the two is top and which is front ?

And what is an mcq :rolleyes: ?

I assumed that the first one was Top and bottom one was Front, in the same order as stated in the question.
Sorry i forgot to post the options, just posted the figure. Anyways, here is the question. It says in brackets "Top and front view" so i assumed the views were in the same order i.e. 1st one top and the bottom one Front.

Welcome!
Just see all lines like planes that are perpendicular to the paper on which the drawing is represented.
One view only gives you two options for the direction of that plane: extending toward your eyes or away from them.
The second view tells you which option is correct.

For this specific shape, some lines are the convergence of two planes, one of which is not perpendicular to the paper.

Begin with drawing the footprint of the shape in the third view, using the dimensions from the other two views.
