Draw the third view and the points on each view

Click For Summary

Discussion Overview

The discussion revolves around a homework problem involving the drawing of a third view and the placement of points on each view in a technical drawing context. Participants are examining the orientation and representation of views based on given sketches.

Discussion Character

  • Homework-related
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant questions whether their rotation of the views is appropriate and if the right view should be considered lateral.
  • Another participant notes that the right view appears more interesting but suggests that points 'a' and 'b' should be at different heights, expressing uncertainty about the interpretation of the sketches.
  • There is a request for clarification on the placement of points 'b' and 'c', with a participant expressing confusion over the relative rotation of the views.
  • A suggestion is made to minimize hidden lines for clarity and to move the third view to the opposite side for better readability.
  • One participant points out that the drawings utilize first angle projection, which is common in Europe, contrasting it with third angle projection used in the U.S.
  • There is a recommendation to maintain consistent line thickness and weight in the drawings.

Areas of Agreement / Disagreement

Participants express differing views on the correct orientation and representation of the drawings, indicating that multiple competing interpretations exist. The discussion remains unresolved regarding the correct placement of points and the implications of the views' rotations.

Contextual Notes

There are limitations related to the assumptions about the meaning of symbols used in the drawings, as well as the potential confusion arising from the use of different projection methods.

Homework Statement


Draw the third view and the points on each view. In the first picture you have what the exercise has given us and in the second what I have drawn. I have turned the page so that the first view is the one on the left, the horizontal one is the one on the right. Is that OK? Should I use the one at the right as a lateral view?

The view from the right (using the orientation in your sketch) is a bit more interesting, but it looks similar to the one from the left.

I would expect b and a to be at a different height (again, in your sketch), but I'm not sure if I interpret the pictures correctly.

Why did you rotate the pictures?

Why did you rotate the pictures?
I rotated the pictures before uploading so that they would seem the same as they are in reality. (While photographing them they rotated in the wrong direction.) I don't know if I did it right to put the view on the right at the exercise as the vertical view. Should it be lateral? Where should b and c be?
 
It is just confusing with the relative rotation.

Unless the ' and '' have some meaning I'm not aware of (=not just indicating which type of view they are drawn on), are those points not at the first visible surface?
 
The drawing is easier to read if you minimize hidden lines, so I'd move the third view to the opposite side.

Note you are using first angle projection here, which is common in Europe. (The U.S. uses third angle projection.)

Keep the line thickness and line weight of the circle the same as the straight lines.
